Question

Viết PTHH thực hiện dãy chuyển đổi hoá học sau : Etilen—> rượu etylic—>Axit axetic—> Etyl axetat—> canxi axetat—> natri axetat

Answer 1

\(C_2H_4+H_2O\underrightarrow{^{170^0C,H_2SO_4}}C_2H_5OH\)

\(C_2H_5OH+O_2\underrightarrow{^{\text{men giấm}}}CH_3COOH+H_2O\)

\(CH_3COOH+C_2H_5OH⇌CH_3COOC_2H_5+H_2O\left(Đk:H_2SO_{4\left(đ\right)},t^0\right)\)

\(2CH_3COOC_2H_5+Ca\left(OH\right)_2\underrightarrow{^{t^0}}\left(CH_3COO\right)_2Ca+2C_2H_5OH\)

\(\left(CH_3COO\right)_2Ca+Na_2CO_3\rightarrow2CH_3COONa+CaCO_3\downarrow\)

 

Answer 2

\(C_2H_4 + H_2O \xrightarrow{t^o,xt} C_2H_5OH\\ C_2H_5OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O\\ CH_3COOH + C_2H_5 \rightleftharpoons CH_3COOC_2H_5 + H_2O\\ 2CH_3COOC_2H_5 + Ca(OH)_2 \to (CH_3COO)_2Ca + 2C_2H_5OH\\ (CH_3COO)_2Ca + Na_2CO_3 \to CaCO_3 + 2CH_3COONa\)
