introduction | acetic acid-L-menthyl ester is also called L-menthyl acetate, acetic acid-L-menthyl ester exists in many varieties of peppermint oil. There are reports that it can be used for the resolution of some chiral amines. |
preparation method | L-menthol (57.4g;0.37mol) was dissolved in methyl acetate (57.4g;0.29mol) and reacted with ketene at 90°C. The conversion was completed after 6 hours, and GC showed that the crude product already contained 99% weight of acetic acid-L-montelyl ester. |
biological activity | Menthyl acetate (L-Menthyl acetate) is a derivative of L-menthol. Menthyl acetate can effectively enhance 5-aminolevulinic acid (ALA) skin penetration. |
chemical properties | there are l-type and dl-type, and general consumption refers to l-type. Colorless or slightly yellow transparent liquid. It has a soft mint and berry aroma, and has a cool and spicy feeling. Boiling point 227~228 ℃, flash point 92 ℃, optical rotation -72 47 '~ 73 18'. Soluble in ethanol, propylene glycol and most non-volatile oils, slightly soluble in water and glycerin. Natural products are found in pepper-like peppermint oil, etc. |
use | GB 2760-1996 specified as allowed edible spices. Mainly used to prepare mint, fruit and berry flavors. |
production method | is obtained from single separation of pepper-like peppermint oil (type l). In the presence of anhydrous sodium acetate, it is obtained by washing and distillation after the reaction of menthol and acetic anhydride (dl type). |
