a)2CH4===>C2H2+3H2
C2H2 + H2O ===> CH3COH
2CH3COH+H2===>2CH3CH2OH
CH3CH2COH+KBr===>CH3CH2Br +KOH
CH3CH2Br+Na ===> C2H4+NaBr
C2H4+H2O===>CH3CH2OH
CH3CH2OH+СuO===> CH3COH + Cu +H2O
б) CH4 + O2 ===> HCHO + H2O
HCHO +H2===>CH3OH
CH3OH+KCl===>CH3Cl+KOH
2СН3СL + 2Nа ===> С2Н6+ 2NаСL
C2H6===>C2H5OH
Проходит в две стадии:
1)C2H6===>C2H4+H2
2)C2H4+H2O===>C2H5OH
C2H5OH + CuO ===> CH3COH + Cu + H2O
