Menthone 1,2-glycerol ketal - Uses and synthesis methods
synthesis mechanism
Menthone glycerol ketal is a semi-ketal formed by the condensation of the carbonyl group of menthone and the hydroxyl group of glycerol under acid catalysis. The generated semi-ketal is unstable and will be directly condensed with the hydroxyl group that is not involved in the reaction of glycerol. Menthone glycerol ketal and one molecule of water are formed.
Toxicity
GRAS(FEMA).
use limited
FEMA(mg/kg): alcohol-free beverage 10~15; Baked products, candy, 50~80; Gum sugar 500~800.
