| titleOfInvention | A kind of production method of borate |
| abstract | The invention provides the production method of a kind of borate, comprise the following steps: boric acid is carried out esterification, evacuation with the alcohol ether passed into continuously, obtain the distillation and the borate that separate; Described distillation is distilled, obtains the water and the alcohol ether that separate. Boric acid and alcohol ether, in borate production process, are carried out esterification by the present invention, and evacuation, makes reaction system reach condition of high vacuum degree, water and alcohol ether are distilled out reaction system, and obtains borate simultaneously; Subsequently water and alcohol ether are distilled again, thus water is separated with alcohol ether. The present invention by repeatedly distilling in acid esterification process, obtain the borate that purity is higher, make water and the alcohol ether obtain sufficient separation, it is to avoid the problem adding water entrainer that water entrainer the causes residual in reaction system and environmental pollution simultaneously. |
