There are two main routes for the industrial synthesis of iso-octanoic acid. One is the oxidation method of iso-octanoic acid, which has high selectivity, reliable raw material source and simple operation. However, the process is long and not easy to scale production. Second, butyral as raw material, through condensation dehydration to produce 2-ethylhexenal, then hydrogenation to obtain 2-ethylhexenal, and then oxidation to isoctanoic acid, this route of raw material source is reliable, Moreover, the aldehyde oxidation method is continuous, fully closed process, easy to scale production, some large companies in Europe and the United States adopt the route of production, our country's gild research institute and Qilu petrochemical research Institute have successfully developed butyral method synthesis isoctanoic acid technology, and have established the industrial plant. Isoctanoic acid price

Quantitative analysis is mainly used for salt, the cobalt, manganese salt, sodium salt, calcium salt is coating the excellent performance of drier, the current domestic paint drier is mainly used in the production of cobalt naphthenate, zinc, manganese, etc, due to the different octylic acid metal salt than naphthenic acid hydrochloric acid value is high, and the acid value and molecular weight of drier volatile speed, stable Product color light, not yellowing and other advantages, has become the replacement of naphthenic acid metal salt products, at present about half of the domestic coating enterprises in the use of isoctanoate coating drying agent, the current coating industry consumption of isoctanoic acid is about 5700 tons. The traditional thickening agents used in the ink industry are aluminum stearate and aluminum C7-9 acid, which have the disadvantages of low thickening efficiency, poor gel stability and heavy smell of products. With the gradual improvement of ink products in recent years, aluminum isoctanoate as a thickening agent of new ink, has good thickening effect, good thickening product stability and easy to control. Although the ink industry is still in its infancy, consumption is very small, but the future market prospects are good.

Isoctanoic acid in the application of plastic additives has also been rapidly developed, isoctanoic acid triglyceride is an excellent plasticizer, tin isoctanoic acid is the production of polyurethane elastomer, polyurethane foam, polyurethane paint and other polyurethane products indispensable drying agent; Cobalt isoctanoate, cadmium, potassium, zinc, tin, lead and calcium are colorless and transparent promoters of unsaturated polyester and silicone rubber vulcanization promoters with excellent properties. With the rapid development of synthetic resin in China, isoctanoic acid in the field of synthetic resin application is considerable at present, the annual demand is about 2000 tons.

Isoctanoic acid has a wide range of applications, such as new refrigeration lubricants (for non-CFC cooling systems) for isoctanoic acid demand is increasing rapidly; Isoctanoic acid is an indispensable raw material for the preparation of ampicillin and carboxylbenzillin. Potassium and sodium isoctanoate can be used as synergists of tetraethyl lead in gasoline. Adding cobalt isoctanoate and ammonium salt to gasoline can slow down fuel consumption and improve its efficiency. Cobalt isoctanoate as dry component can improve the wet strength of paper; Cobalt isoctanoate is commonly used as a thickening agent for daily cosmetics. Isoctanoic acid can improve THE dyeability AND weather resistance of polyOLEFin synthetic fiber, and it is used as a high energy rocket propellant and an additive in manufacturing solidification fuel in military industry, in addition, it can also be used as rubber adhesive promoter, wood preservative, synthetic high density polyethylene initiator, etc. These fields currently consume about 900 tons of isoctanoic acid.
