وهذا الحل بالمعادلات طبقا لجواب الأستاذعلي الملط

CaC2+2H2O.................>Ca(OH)2 + C2H2
C2H2+H2O...................>CH3CHO
CH3CHO+(O)................>CH3COOH
CH3COOH+NaOH................>CH3COONa+H2O
CH3COONa+NaOH.............(CaO)..........>CH4 +Na2CO3
CH4+H2O......................(cat)...........>CO+3 H2
