use | used as a chemical reagent, also used in the synthesis of spices and organic substances used in the manufacture of emulsifiers, waterproofing agents, curing agents, polyvinyl chloride heat stabilizers and plasticizers, etc., are also raw materials for spices and medicines determination of calcium and magnesium in hard water. Organic synthesis. Mainly used as a raw material for the production of surfactants, used for the production of sorbitan fatty acid esters, glycerin fatty acid esters, ethylene glycol or propylene glycol fatty acid esters, etc. It can also be used to produce isopropyl myristate. Also used in defoaming agent, flavoring agent. According to the GB2760-89 regulations of our country, it can be used to prepare various edible spices. |
production method | mixed fatty acid or methyl ester of mixed fatty acid obtained from coconut oil and palm kernel oil can be obtained by vacuum fractionation in drought. Laboratory preparation can be saponified by tricylglycerol (decanoic acid) ester and 10% sodium hydroxide solution, and then acidified with hydrochloric acid to obtain free decanoic acid. It can also be taken by the decane alcohol method. It is obtained by vacuum fractionation of mixed fatty acids or methyl esters of mixed fatty acids obtained from coconut oil and palm kernel oil. |
