4-chlorobenzene sulfonamide

Both the dilution temperature and temperature of the aminolysis beating have been raised from 5℃ to 15℃,the yield of 4-chlorobenzene sulfonamide was raised from 75% to 80.

以氯苯为原料,以四氯化碳为溶剂,经氯磺化、氨解合成了4-氯苯磺酰胺。

In the study, the effects of different treatments (AgNO3, GA3, KT, TDZ and 4℃ ) on seed dominancy were studied.

本实验以AgNO3、GA3、KT、TDZ和4℃低温处理凤丹种子,探讨解除其上胚轴休眠的途径。
