| use | methyl laurate is an important raw material for daily cosmetic essence and soap making industry, and it is also a new type of food emulsifier with high efficiency, safety, non-toxic and pollution-free The raw material of sucrose laurate and the raw material for synthesizing a variety of anionic surfactants and non-ionic surfactants are important intermediates in fine chemical industry. Used as an intermediate in organic synthesis. Methyl laurate is a flavor ketone produced by the catalyzed reaction of microencapsulated fungal spores. It is also used to produce biodiesel. Used as gas chromatography stationary liquid, food additive and organic synthesis reagent gas chromatography analysis standard. Organic synthesis. |
| Preparation | Methyl laurate can be obtained by esterification of lauric acid and methanol. The mixture of lauric acid, anhydrous methanol and concentrated sulfuric acid is heated and refluxed for 18h, and the reaction is poured into water to separate the ester layer. Wash with water, saturated sodium bicarbonate solution and water in turn. After drying, it is distilled, and the 260-263 ℃ fraction is collected, which is methyl diproate. |
| toxicity | GRAS(FEMA). |
| usage limit | FEMA(mg/kg): soft drinks, cold drinks, 0.50~5.0; Candy 0.02-0.50; Baked products 1.0. FDA(§ 1 72.515,2000): Moderate limit. |
| production method | obtained by esterification of lauric acid and methanol.

Wash with water, saturated sodium bicarbonate solution and water in turn. After drying, distillation is carried out, and the 260-263 ℃ fraction is collected, which is methyl diproate with 81% yield. |
