\(CH_3COOH+Na\rightarrow CH_3COONa+\dfrac{1}{2}H_2\)
\(CH_3COONa+NaOH\underrightarrow{t^o,CaO}CH_4+Na_2CO_3\)
\(2CH_4\underrightarrow{1500^oC}CH\equiv CH+3H_2\)
\(2CH\equiv CH\underrightarrow{t^o,xt}CH_2=CH-C\equiv CH\)
\(CH_2=CH-C\equiv CH+H_2\underrightarrow{Pd,t^o}CH_2=CH-CH=CH_2\)
\(nCH_2=CH-CH=CH_2\underrightarrow{t^o,xt,p}\left(CH_2-CH=CH-CH_2\right)_n\)
