Used as reducing agent and fungicide.
The largest user of acetaldehyde is the acetic acid industry. Butanol and octanol were also important derivatives of acetaldehyde in the past, but now they are basically replaced by propylene carbonyl synthesis. Other areas of consumption of acetaldehyde are the production of pentaerythritol, peracetic acid, pyridine and their derivatives. Domestically produced acetaldehyde is basically used as an intermediate in the production of acetic acid, and only a small amount is used to produce pentaerythritol, butanol, chloral, trimethylolpropane and other products. Acetaldehyde can be used to produce acetal, crotonaldehyde, peracetic acid, hydroxypropionitrile, chloral, ethyl acetate, pentaerythritol, acetic anhydride, acetic acid, glyoxal, phenylacrolein, acetal, methylethylamine , diethylamine, α-alanine, pyridine, α-picoline, β-picoline, γ-picoline.
