3,反应的化学方程式为:HOOCCOOH+2CH3CH2OH?浓H2SO4△?△浓H2SO4CH3CH2OOC-COOCH2CH3+2H2O,油状液体中有乙醇、乙二酸等杂质,用饱和碳酸钠溶液吸收主要目的是除去酯中混有的乙二酸和乙醇,同时减小酯在水中的溶解度,便于分层析出,得到较纯的CH3CH
(2)乙醇与浓H2SO4加热至170℃制取乙烯:CH3CH2OH→浓硫酸170℃→170℃浓硫酸CH2=CH2↑+H2O (3)乙醇与O2、Cu共热:2CH3CH2OH+O2→铜△→△铜2CH3CHO+2H2O (4)丙醛与银氨溶液水浴加热:CH3CH2CHO+2Ag(NH3)2OH水浴→→水浴CH3CH2COONH4+2Ag↓+3NH3+H2O ...
Electronic structure and the vibrational frequencies of CH3(OCH2CH2)nOCH3−M−CF3SO3-(n 2−4, M Li, Na, and K) complexes have been derived from ab initio Hartree−Fock calculations. The metal ion shows varying coordination from 5 to 7 in these complexes. In tetraglyme−lithium ...
