| overview | methyl hexanoate, also known as methyl palmitate. Methyl palmitate is a raw material for surfactants and other fine chemical products. It is an excellent intermediate for the manufacture of emulsifiers, wetting agents, stabilizers, rust inhibitors and plasticizers. It can also be used for interbiological pheromones and biodiesel., Cosmetic raw materials and preparation of plant acaricides. |
| application | methyl palmitate is a colorless liquid or crystal (precipitated in ethanol at -15 ℃), easily soluble in alcohol, acetone, chloroform and benzene, soluble in ether, insoluble in water, and used as an intermediate for emulsifier, humectant, stabilizer and plasticizer; methyl palmitate is a very common and high content in nature A substance, it is the main component of some edible trees and vegetables, medicinal plants, ornamental plants, and various wild plants. It is also one of the main components of some animal fatty substances. For example, the fatty oil of mole cricket contains a certain amount of hexanoate. Methyl ester is also a raw material for biopheromone, biodiesel, and cosmetics (emulsifier, medicine). |
| preparation | at present, there are two main methods for obtaining methyl palmitate. one is to prepare fatty acid methyl ester mixture through transesterification reaction between palm oil and methanol under alkaline catalytic conditions for biodiesel. The second is to prepare methyl palmitate by direct dehydration and esterification of palmitic acid and methanol with concentrated sulfuric acid as catalyst. In the direct esterification method, concentrated sulfuric acid has serious corrosion to the equipment, the product is not easy to separate, the post-treatment process is complicated, and the wastewater causes serious pollution to the environment. In addition, due to the strong oxidation of concentrated sulfuric acid during the reaction process, the color of the product is easy to deepen. |
| use | used as an intermediate for emulsifier, wetting agent, stabilizer and plasticizer, and also used as a gas chromatography stationary liquid organic synthesis. |
