Combine and dehydrate to obtain 2-ethylhexenal. 2-Ethylhexenal is hydrogenated in the presence of a nickel catalyst at a certain temperature and pressure to produce iso-2-ethylhexanol.

Purpose

1. Used in the production of plasticizers, defoaming agents, dispersants, antioxidants, mineral processing agents and petroleum additives, and also used in printing and dyeing, paint, film, etc. Mainly 2. Used to manufacture ester plasticizers and cold-resistant auxiliary plasticizers for dicarboxylic acids such as phthalic acid, azelaic acid, and sebacic acid. The mixed solvent used in nitrocellulose spray paint can prevent the paint film from turning white. 3.2-Ethylhexanol is commonly called octanol in the plasticizer community, and it is an important chemical raw material. In addition to being used to produce plasticizers abroad, octanol also produces octyl acrylate or is used as a surfactant, etc. It can mainly be used to produce: dioctyl phthalate (DOP), dioctyl oxalate (DOA), Trioctyl trimellitate (TOTM), other plasticizers, octyl acrylate, surfactants, bone oil additives, mining, diesel fuel additives, solvents and dispensing, rust inhibitor esters, other chemicals. Octanol itself is a useful solvent, defoamer, dispersant, and lubricant. Its series of products are mainly plasticizers such as dioctyl phthalate and octyl acrylate. Dioctyl phthalate produced from octanol is the main plasticizer of PVC, and its consumption for PVC accounts for about 95% of its total consumption. 4. It is used as a defoaming agent for white latex, but its ability to break and suppress foam is poor. It is also used as raw material for organic synthesis to produce products such as octyl acrylate, dioctyl phthalate, dioctyl terephthalate and dioctyl sebacate. It is also used as a dispersant, lubricant, antioxidant, emulsifier, mineral processing agent, mercerizing agent, etc. It is also an excellent solvent and is used in paper sizing, latex and photography. The mixed solvent prepared with it can prevent the paint film from turning white when used in nitrocellulose spray paint. 5. Commonly used in baked goods, frozen dairy products, and puddings.
