Question

\(CH_4\xrightarrow[]{\left(1\right)}A\xrightarrow[]{\left(2\right)}B\xrightarrow[]{\left(3\right)}C\xrightarrow[]{\left(4\right)}D\xrightarrow[]{\left(5\right)}E\xrightarrow[]{\left(6\right)}F\xrightarrow[]{\left(7\right)}CH_4\)

Xác định các chất và viết PTHH

Answer 1

\(CH_4\rightarrow C_2H_2\rightarrow C_2H_4\rightarrow C_2H_5OH\rightarrow CH_3COOH\rightarrow\\ CH_3COOC_2H_5\rightarrow CH_3COONa\rightarrow CH_4\)

PTHH:

\(\left(1\right)2CH_4\xrightarrow[\text{làm lạnh nhanh}]{1500^oC}C_2H_2+3H_2\\ C_2H_2+H_2\xrightarrow[t^o]{Pd\text{/}PdCO_3}C_2H_4\\ \left(3\right)C_2H_4+H_2O\xrightarrow[axit]{t^o}C_2H_5OH\\ C_2H_5OH+O_2\xrightarrow[]{\text{men giấm}}CH_3COOH+H_2O\\ CH_3COOH+C_2H_5OH\xrightarrow[t^o]{H_2SO_{4\left(đ\right)}}CH_3COOC_2H_5\\ CH_3COOC_2H_5+NaOH\rightarrow CH_3COONa+C_2H_5OH\\ CH_3COONa+NaOH\rightarrow Na_2CO_3+CH_4\)
