market status and development analysis of isooctanoic acid products at home and abroad

March 29, 2005

isooctanoic acid and its salts are important fine chemicals, which are mainly used as accelerators and catalysts for various unsaturated polyester resins; Paint and ink driers; PVC processing aids; Metalworking and lubricating AIDS; Oil additives; Rubber vulcanization accelerator; In addition, as an intermediate, it can synthesize medicine, dyes, pesticides and spices. In recent years, isooctanoic acid is in short supply in domestic and foreign markets, and the construction of devices has been significantly accelerated

production technology

there are two main routes for the industrial synthesis of isooctanoic acid. One is the isooctanol oxidation method, which has high selectivity, reliable source of raw materials and simple operation, but the process flow is long and it is not easy to scale production. Many small-scale units in China adopt this route for production; Second, butyraldehyde is used as raw material to produce 2-ethylhexenal through condensation and dehydration, then hydrogenation to produce 2-ethylhexenal, and then oxidation to produce isooctanoic acid. The raw material source of this route is reliable, and the aldehyde oxidation method is a continuous, fully closed process, which is easy for large-scale production. Some large companies in Europe and America mostly use this route for production. China's Jihua Research Institute and Qilu Petrochemical Research Institute have successfully developed the process technology of synthesizing isooctanoic acid by butyraldehyde method, Industrial installations have been built


there are nearly ten isooctanoic acid production enterprises in China, with an annual production capacity of about 15000 tons/year. Among them, Shenyang Applied Technology Experimental Factory is the largest production enterprise in China, with an annual production capacity of about 6000 tons/year. At present, it is planning to expand to 10000 tons/year; Other enterprises are small, mostly hundreds of tons/year. At present, in the domestic isooctanoic acid industry, except for Shenyang Applied Technology Experimental Factory, which has begun to take shape, and the product quality, specification and performance are relatively ideal, most other enterprises have small production capacity, unstable product quality and single specification, so most enterprises are in the state of shutdown or semi shutdown

application and consumption

isooctanoic acid is mainly used for salt formation. Its cobalt salt, manganese salt, sodium salt and calcium salt are excellent driers for coatings. At present, the driers used in domestic paint production are mainly naphthenates of cobalt, zinc, manganese, etc. because isooctanoic acid metal salt has higher hydrochloric acid value than naphthenic acid metal salt, and its acid value and molecular weight are stable, the drying and volatilization speed is fast, and the product color is light and does not turn yellow, It has become an updated product of naphthenic acid metal salt. At present, about half of domestic coating enterprises are using isooctanoic acid paint driers. At present, the consumption of isooctanoic acid in the coating industry is about 5500 tons

the traditional thickeners used in the ink industry are aluminum stearate and aluminum citrate, which have the disadvantages of low thickening efficiency, poor gel stability, heavy product odor and so on. With the gradual improvement of the grade of ink products in recent years, aluminum isooctanoate, as a thickener for new inks, has good thickening effect, good thickening product stability, and easy to control operation. Although its application in the ink industry is still in its infancy, its consumption is very small, But the future market prospects are promising

the application of isooctanoic acid in plastic additives has also developed rapidly. Glyceride of isooctanoic acid is an excellent plasticizer, and tin isooctanoic acid is an indispensable drying agent for the production of polyurethane elastomers, polyurethane foams, polyurethane paints and other polyurethane products. Windows kernel driver DLL technology is used as the data collection driver; Cobalt, cadmium, potassium, zinc, tin, lead and calcium isooctanoate are colorless transparent accelerators of unsaturated polyester and vulcanization accelerators of silicone rubber with excellent properties. With the rapid development of synthetic resin in China, isooctanoic acid is widely used in the field of synthetic resin, with an annual demand of about 1800 tons

isooctanoic acid has a wide range of applications, such as new refrigeration lubricants (for non CFC cooling systems) with a rapid increase in demand for isooctanoic acid; Isooctanoic acid is an indispensable raw material for the preparation of ampicillin and carboxybenzylpenicillin; The test repeatability is low. Potassium and sodium isooctanoate can be used as synergists of tetraethyl lead in gasoline. Adding cobalt isooctanoate and ammonium salt to gasoline can slow down fuel consumption and improve its efficiency; Cobalt isooctanoate as a drying component can improve the wet strength of paper; Cobalt isooctanoate is a thickener commonly used in daily cosmetics; Isooctanoic acid can improve the dyeability and weatherability of polyolefin synthetic fibers. It is used as an additive for high-energy rocket propellants and solidified fuels in the military industry. In addition, it can also be used as a rubber adhesion promoter, wood preservative, initiator for the synthesis of high-density polyethylene, etc. These fields currently consume about 800 tons of isooctanoic acid

based on the above, the current annual consumption of isooctanoic acid in China is about 7100~8000 tons. According to the current domestic production capacity, it can fully meet the needs of the domestic market. Due to the overall low level of domestic isooctanoic acid, there are many contradictions. First, different domestic users have different requirements for the quality of isooctanoic acid, and have relatively high requirements in the fields of medicine, synthetic resin accelerators, catalysts and so on, Many domestic enterprises are unable to meet their quality requirements. In addition, there is still a large gap in domestic production technology and scale, which leads to higher production costs. Many coating enterprises have delayed using isooctanoate to replace naphthenate because of its high price. The potential demand for isooctanoate in the high-end ink and coating industry is very large. If the price of domestic products can be further reduced, It is estimated that at present, the demand for isooctanoic acid in the above two fields will reach about 8000 tons, and the domestic product quality and price restrict the domestic consumption of isooctanoic acid. Second, in previous years, isooctanoic acid was in great demand in the international market, so famous foreign isooctanoic acid production enterprises such as Eastman company of the United States have expanded their production capacity to meet market demand. Even when the foreign market was in short supply, China still imported a certain amount of isooctanoic acid products every year to meet domestic demand, and a large number of imports had an impact on domestic production devices, As a result, many small and medium-sized enterprises in China are in the state of shutdown or semi shutdown. At present, China has become the second largest paint producer in the world after the United States, especially the rapid development of high-grade paint. In addition, the domestic synthetic resin and unsaturated polyester industry has developed rapidly, and medicine and high-grade ink have also shown a rapid development trend. Therefore, many people in the industry predict that the demand for isooctanoic acid in China will increase at an average annual rate of about 15% in the next few years, and the isooctanoic acid Market in the international market will also increase steadily, It brings huge market space for the development of isooctanoic acid in China. Due to the low domestic production level, especially the low scale, and the unreasonable matching of raw materials, the production situation does not match the potential market demand, and foreign products have a certain impact on the domestic market. Therefore, it can be said that China's isooctanoic acid industry has both opportunities and challenges

development direction

according to the current situation and market demand of isooctanoic acid industry in China, the following suggestions are put forward to promote the healthy and orderly development of isooctanoic acid industry in China

first of all, from the perspective of foreign production experience, the petrochemical route using butyraldehyde and 2-ethylhexenal as raw materials is a relatively reasonable and suitable industrial route for large-scale production. Therefore, domestic petrochemical enterprises can take advantage of their own resource advantages to improve the 2-ethylhexenal route synthesis technology and build large-scale production plants. It is suggested that the scale should be more than 5000 tons/year, In this way, the scale effect and the upstream and downstream integrated production mode can be used to reduce production costs, promote the market consumption of isooctanoic acid and resist the impact of foreign products

secondly, according to the needs of different domestic users, we can produce products with different quality specifications, especially increase the production and development of high-purity isooctanoic acid. Although the demand in these fields is not as large as that in the coating industry, they can be used as high-purity products in the fields of pharmaceutical raw materials, catalysts and initiators, which have relatively high added value and can obtain good economic benefits

finally, like the development of many fine chemical intermediates, China's isooctanoic acid industry should not only focus on the domestic market, but also position the product specification and quality with the international market. After the device is scaled up, we should speed up the development of the domestic potential market and strengthen the development of the international market
