| titleOfInvention | It is a kind of to improve N, the purity of O-bis- (trimethylsilyl) acetamide and the production method of yield simultaneously |
| abstract | The present invention provides a kind of while improves N, the purity of O-bis- (trimethylsilyl) acetamide and the production method of yield, includes preparation, charging, synthetic reaction, the distillation of trim,ethylchlorosilane；It is described distillation include distill front-end volatiles, distill to obtain finished product；The preparation of the trim,ethylchlorosilane, it is 2.11 2.22 according to the mol ratio of trim,ethylchlorosilane and acetamide:1, by trim,ethylchlorosilane according to trim,ethylchlorosilane head tank is extracted into, the vacuum for starting to keep trim,ethylchlorosilane head tank before feeding is 0.001 0.005MPa.Product BSA prepared by the present invention, product purity bring up to 99.58 99.66%；Amount of impurities and content are reduced, and amine content is 0.20 0.25%；For BSA once through yield up to 93.42 93.7%, feed stock conversion is high, and more than 3% is improved compared with prior art. |
