ACROLEIN PRODUCTION METHOD AND ACRYLIC ACID PRODUCTION METHOD

摘要

Disclosed are an acrolein production method and an acrylic acid production method, each of which enables to produce acrolein from a glycerin mixture comprising a fatty acid and/or a salt of a fatty acid, glyceride, a fatty acid ester and the like with a little consumption of energy. Specifically disclosed is an acrolein production method comprising the steps of: dehydrating glycerin in the glycerin mixture to produce an acrolein mixture comprising acrolein, a fatty acid and/or a salt of a fatty acid and the like; and collecting acrolein from the acrolein mixture. Also specifically disclosed is an acrylic acid production method comprising the step of reacting acrolein produced by the acrolein production method with molecular oxygen.
