CaC2 → C2H2 → C2H4 → C2H5OH → CH3CHO→CH3COOH → CH3COOCH5

1. CaC2 + 2H2O -> Ca(OH)2(осадок) + HC=-CH
2. HC=-CH + H2 ->(Pt, t*) H2C=CH2
3. H2C=CH2 + H2O ->(H3PO4) H3C-CH2OH
4. H3C-CH2OH + 2CuO ->(t*) H3C-COH + Cu2O + H2O
5. H3C-COH + Ag2O -> H3C-COOH + 2Ag
6. H3C-COOH + CH3OH <->(H2SO4) H3C-COOCH3 + H2O

В скобках писал катализаторы, их нужно писать над стрелочкой
