| titleOfInvention | A kind of preparation method of lauric acid methyl tin |
| abstract | A kind of preparation method of lauric acid methyl tin, this method is using methyl chloride tin aqueous solution, lauric acid and lye as primary raw material, one-step synthesis lauric acid methyl tin.The following steps are included: (1) is heated and is stirred mixture by lauric acid, methyl chloride tin aqueous solution investment reaction kettle, when temperature reaches 50~70 DEG C, start that lye is added dropwise；(2) temperature of reaction system is controlled between 50~70 DEG C, continues that lye is added dropwise, and when mixed liquor pH value reaches 4~7, is stopped that lye is added dropwise, is stood split-phase；(3) it takes organic phase to wash, then stands split-phase；(4) organic matter is evaporated under reduced pressure to the low boiling impurities such as abjection water between 60~140 DEG C of temperature, refilters and obtains lauric acid methyl tin.The present invention is not related to the dust raw material such as methyl oxidation tin, avoids lauric saponification, and waste water recoverable has the characteristics that production equipment is simple, easily controllable, manufacturing cost is low, stable product quality. |
