MENTHONE GLYCERIN ACETAL - 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.

MENTHONE GLYCERIN ACETAL - Introduction
Menthone 1,2-glycerol ketal, also known as menthol glyceride, is an organic compound. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
Menthone 1,2-glycerol ketal is a colorless to pale yellow liquid with a strong mint fragrance. It is compatible with many common solvents and oils, but insoluble in water. The compound has a cooling and tingling sensation and is commonly used as a food and pharmaceutical additive.
Use:
Menthone 1,2-glycerol ketal is widely used in various fields. It is a common ingredient in many toothpastes, chewing gums, candies and oral preparations to increase the cooling sensation in the mouth. In addition, it is also used as a fragrance additive to give the product a fresh mint fragrance. Menthone 1,2-glycerol ketal can also be used to make products such as throat lozenges, biscuits and mouth sprays.
Preparation Method:
The preparation method of Menthone 1,2-glycerol ketal is mainly obtained by ketal reaction of menthol and glycerides. This process is usually carried out in an appropriate solvent at low temperature and under acidic conditions. The preparation process requires attention to the operating conditions and the elimination of alkaline substances to avoid the production of impure substances.
Safety Information:
Menthone 1,2-glycerol ketal is generally considered to be a relatively safe compound, but the following points still need to be paid attention:
1. Exposure to Menthone 1,2-glycerol ketal may cause eye and skin irritation. Wear appropriate protective gloves and eye protection equipment when using or preparing the substance.
2. Inhalation of high concentrations of Menthone 1,2-glycerol ketal may cause respiratory irritation and discomfort. Therefore, when using or preparing the substance, ensure adequate ventilation and try to avoid inhalation.
3. Menthone 1,2-glycerol ketal should be kept away from open flames and high temperatures to prevent it from causing combustion and explosion.
4. Store the substance out of reach of children to prevent ingestion or misuse.
In General, Menthone 1,2-glycerol ketal is a commonly used compound widely used in food, medicine and spices. During use and preparation, attention should be paid to appropriate protection and storage measures to ensure safe use.
