1)
2CH4--- 1500 độ C; làm lạnh nhanh -> C2H2 +3H2
C2H2 + H2O--xt; to--> Ch3CHO
CH3CHO + H2--xt--> C2H5OH
2C2H5OH - xt---> C4H6 +2H2O + H2
C4H6 + 2H2 -> C4H1)
C4H10 ---xt; to->C3H6 + CH4
C3H6 + H2O -> CH3-CHOH-CH3
2)
CH3COONa + NaOH -- CaO; to-> CH4 + Na2CO3
C2H6 + Cl2-- as-> C2H5Cl + HCl
2C2H5Cl +2Na---ete khan-> C4H10 +2NaCl
C4H10->C3H6 + Ch4
CH4 + O2--xt-> HCHO + H2O
HCHO + O2 -> CO2 + H2O
3) C3H7Cl + NaOH -> C3H7OH + NaCl
C3H7OH + CuO--to-> C3H6O + Cu + H2O
CH3-CH2-CHO +1/2 O2---xt->CH3-CH2-COOH
C3H7OH --xt-> C3H6 + H2O
CH2=CH-CH3 + HCl -> CH3-CHCl-CH3
CH3-CHCl-CH3 + NaOH->CH3-CHOH_CH3 + NaCl
CH3-CHOH-CH3 + CuO --to -> CH3-CO-CH3 + Cu + H2O
