Acetaldehyde use
[Purpose 1]
It is mainly used to prepare acetic acid, acetic anhydride, butyraldehyde, octanol, pentaerythritol, tripolyacetaldehyde and other important chemical raw materials
[Purpose 2]
Used as reducing agent and bactericide
[purpose 3]
It is mainly used for the preparation of acetic acid, acetic anhydride, ethyl acetate, butanol, pentaerythritol, tripolyacetaldehyde, 3-hydroxybutanal, Trichloroacetaldehyde and other products
[Purpose 4]
GB 2760-1996 is a temporary permitted edible flavor. It is mainly used for making citrus, apple, cream and other flavors.
[Purpose 5]
The biggest user of acetaldehyde is acetic acid industry. Butanol and octanol were important derivatives of acetaldehyde in the past, and now they are basically replaced by propylene carbonylation. Other areas of acetaldehyde consumption are the production of pentaerythritol, peracetic acid, pyridine and their derivatives. Acetaldehyde produced in China is basically used as the intermediate of acetic acid production, and only a small amount of acetaldehyde is used to produce pentaerythritol, butanol, Trichloroacetaldehyde, trimethylolpropane and other products. Acetaldehyde can be used to produce acetaldehyde, crotonaldehyde, peracetic acid, hydroxypropiononitrile, Trichloroacetaldehyde, ethyl acetate, pentaerythritol, acetic anhydride, acetic acid, glyoxal, phenylacrolein, acetaldehyde, methylamine, diethylamine, α - alanine, pyridine, α - methylpyridine, β - methylpyridine and γ - methylpyridine.
