氢化物。既然如此,氨水(ammoniawater)只是氨的 水溶液(ammoniaaqueoussolution)的俗称而已。若 只考虑水溶液体系,可简称为氨溶液(ammoniaso2 lution),不应有其他名称,应该在氨水的试剂瓶上 贴上“NH3”的标签。这是合情合理的,是跟化学物 质的命名系统完全一致的。正如你把硫酸铜溶解 于水装进试剂瓶,会毫不犹豫...
Temporal analysis reveals that the emissions are episodic and linked with the lake's surface area. The largest NHcolumn loadings generally occur at the end of the dry season in September鈥揘ovember over Lake Natron's largest mudflat, that is exposed with receding water levels. The timing is ...

First, add part of HN3 water into the reaction pot, stirring for adding p-toluenesulfonyl chloride with the temperature rising naturally to above 50 °C; after the temperature has dropped, add the remaining ammonia and have reaction for 0.5 h at 85~90 °C. Stop the reaction when the pH ...
He finallyabandonedthissuggestionaround 1822 but still insisted that the ammonia became oxidizedatthemomentofneutralizationby reacting with the solvent water. 他最终在1822年左右放弃了这个建议,但仍然坚持认为氨在中和时通过与溶剂水反应而被氧化。 Thus in the reaction between sulfuric acid and ammonia to gi...

Although the synthesis of m-aminophenol(s) by the reaction of resorcinol with ammonia or (di)alkylarnines has been known for about 100 years,the preferred manufacturing process had been for many years a route involving the sulfonation of nitrobenzene to m-nitrobenzenesulfonic acid, the reduction...
