Structural formula of crotonaldehyde CH3CH = CHCHO. It has two double bond cis and trans isomers. The goods is colorless or slightly yellow liquid, flammable, tear resistance, meet the light gradually into the dew in the air or light yellow liquid, by oxidation of crotonic acid. Crotonaldehyde are important intermediates in organic synthesis, and used in the manufacture of butyl aldehyde, food preservatives sorbic acid, synthetic resin, dye, pesticide, dressing with foaming agent, rubber antioxidant, etc.
Organic synthetic raw material, used for making butyl aldehyde, Butanol. 2 - ethyl hexanol; Sorbic acid. 3 - methoxy butyl aldehyde. 3 - methoxy butyl alcohol. Crotonic acid; Sinensis which organism; Maleic anhydride and pyridine series products. In addition, crotonaldehyde and butadiene reaction of epoxy resin can be obtained from raw materials and epoxy plasticizer. With pentaerythritol into four alcohol reaction heat resistant resin raw materials can be obtained. Crotonaldehyde can also be used for preparing dressing with foaming agent; Dye and rubber antioxidant; Pesticides and military chemicals. Industrial-grade crotonaldehyde was actually trans-isomer and isomer of mixture [4170-30-3]. But the cis isomer is not stable, content is less than 1%.
