Question

写出以乙烯为原料合成乙酸乙酯的化学方程式（不用乙烯氧化法） （）；（）；（）；（）

要化学方程式

Answer 1

乙烯+ 水（H-OH） ==乙醇
乙醇+空气催化氧化生成乙酸
乙醇和乙酸酯化生成乙酸乙酯

CH2=CH2 + H-OH ==== CH3-CH2-OH
CH3-CH2-OH + （O）==== CH3-COOH

CH3-CH2-OH + CH3-COOH ===CH3-CO-O-CH2-CH3 + H2O

Answer 2

CH2=CH2+H2O→CH3CH2OH
2CH3CH2OH+O2→2CH3CHO+2H2O
CH3CHO+2Ag(NH3)2+ 2OH-→CH3COONH4+2Ag↓+3NH3+H2O
CH3COONH4+HCl==NH4Cl+CH3COOH
CH3COOH+CH3CH2OH=可逆，H+=CH3COOCH2CH3+H2O

Answer 3

CH2=CH2+HBr-->CH3CH2Br
CH3CH2Br+H2O---NaOH-->CH3CH2OH+HBr
2CH3CH2OH+O2---催化剂，加热--->2CH3COOH+2H2O
CH3CH2OH+CH3COOH--(浓H2SO4，加热）->CH3COOC2H5+H2O

Answer 4

乙烯-乙醇
乙烯-乙醇-乙醛-乙酸
乙醇+乙酸=乙酸乙酯
