These methanols were treated with BF3 in CH2Cl2 to generate the diferrocenylmethyl carbocations. Without separation from the reaction mixture, the ions were treated with some amines RNH2 [R=C2H5, n-C3H7, n-C4H9, HOCH2CH2, HOCH(CH3)CH2, HOCH2CH(C2H5)] to afford the ferrocenylamines in high yields. The present methodology for preparing α-ferrocenylamines from α-ferrocenyl alcohols enjoys such advantages as simple procedure and inexpensive starting materials.

它们对酸的敏感性很高，与BF3在二氯甲烷中作用可形成稳定的二茂铁基甲基碳正离子，无需从溶液中分离出来，便可与胺RNH2[R=C2H5，n-C3H7，n-C4H9，HOCH2CH2，HOCH(CH3)CH2，HOCH2CH(C2H5)]作用得到产率颇高的二茂铁基胺，这种由α-二茂铁基醇制备α-二茂铁基胺的方法具有简单、快速和原料廉价的特点。

The activated Br - and Cl - is released and it will forms HBrO and HClO in further when we put the bormochloro hydantoin in the water, and thus the HBrO and HClO will oxidate the enzymes such as a enzymes with SH so as to sterilize and purify the polluted air.

采用溴氯海因消毒剂在水中能够通过不断释放出活性 Br -和 Cl -，形成次溴酸和次氯酸，将微生物体内的生物酶氧化而达到杀菌的目的。

In relation to the metering pump pump head, the usual questions are emerging in the measurement of acid, chlorine, fluoride and hydrogen peroxide situation.
