问题描述:
写出转化的化学方程式,并注明反应条件:CH3CHO C2H5OH C2H4 C2H5Br.
答
CH3CHO+H2—Ni,△→CH3CH2OH
CH3CH2OH—浓H2SO4,170ºC→H2C=CH2↑+H2O
H2C=CH2+HBr→CH3CH2Br
CH3CH2Br+NaOH—醇,△→H2C=CH2↑+NaBr+H2O
H2C=CH2+H2O—催化剂→CH3CH2OH
2C2H5OH+O2—Cu,△→2CH3CHO+2H2O
C2H5Br+NaOH—△→C2H5OH+NaBr
C2H5OH+HBr→C2H5Br+H2O
答
CH3CHO+H2--C2H5OH(反应条件为催化剂)
C2H5OH --C2H4+H2O(反应条件为浓硫酸 加热)
C2H4+HBr--C2H5Br(反应条件为催化剂)
