It is mainly used in lipid synthesis and the pharmaceutical industry. Does anyone know about this? I’d appreciate some advice

A colorless or slightly yellowish viscous liquid, sensitive to oxygen, flammable, and explosive. It absorbs moisture very easily. Soluble in methanol and ethanol; it decomposes into methanol and sodium hydroxide upon contact with water, and decomposes in air at temperatures above 126.6°C. Insoluble in benzene and toluene. It has a strong irritant effect and is highly corrosive.   It is mainly used as a condensing agent and a strong basic catalyst, as well as a methoxylation agent for the production of vitamins B1 and A, sulfadiazine, and other drugs. A small amount is used in pesticide production. It can also be used as a catalyst for processing edible fats and oils (especially lard). It can also be used as an analytical reagent.   Sodium methoxide is a colorless amorphous powder that is sensitive to oxygen and flammable; it is soluble in methanol and ethanol, and decomposes into methanol and sodium hydroxide when exposed to water. It also decomposes in air at temperatures above 126.6 °C.   Sodium methoxide has a wide range of applications, mainly in the production of sulfonamide drugs, VB6, and VA. It is also used as a catalyst in organic synthesis, in the production of pesticides, and in the oil processing industry.   Sodium methoxide is available in two forms: solid and liquid. The solid form is pure sodium methoxide, while the liquid form is a methanol solution of sodium methoxide, with a concentration of 27.5~31%. Production process: Solid sodium hydroxide and methanol are mixed in a certain ratio; after stirring to facilitate dissolution, precipitation and clarification are carried out to remove solid impurities. The clear solution is pumped to the top of the reaction dehydration tower, while purified methanol vapor is introduced from the bottom of the tower where continuous reaction and dehydration take place, with the product being obtained from the bottom of the tower. The aqueous methanol vapor exits from the top of the tower and enters a distillation system for purification, while the anhydrous methanol is returned for use. I should start by stating that I’m not capable of producing these items myself; I just found them online. I hope this will be helpful to you:loveliness: Sodium methoxide is provided by Shanghai Wan’an Chemical Technology Research Institute. Jinan Hengfa Chemical Co., Ltd. specializes in the production of sodium methoxide, while Shandong Xinhua Junyu Chemical Co., Ltd. is also specialized in its production

Our company has been specializing in the production of sodium methoxide for over a decade. I saw the message a bit late; feel free to contact me if you need it
