2CH4 --(t=1500)-- CHCH + 3H2
3CHCH --(Cакт,t)-- C6H6
C6H6 + CH3Cl --(AlCl3)-- C6H5-CH3 + HCl
5C6H5-CH3 + 6KMnO4 + 9H2SO4 --- 5C6H5-COOH + 3K2SO4 + 6MnSO4 + 14H2O
C6H5-COOH + C2H5OH --(H,t)-- C6H5-CO-O-C2H5 + H2O

2CH4 --(t=1500)-- CHCH + 3H2
2CHCH --(t,kat)-- CHC-CH=CH2
CHC-CH=CH2 + 3H2 --(kat, t)-- CH3-CH2-CH2-CH3
2CH3-CH2-CH2-CH3 + 5O2 --(t,kat)-- 4CH3-COOH + 2H2O
CH3-COOH + NH3 --- CH3-COONH4
