C->Al4C3->CH4->CH3OH->H-CHO->HCOOH-CO2

3C +v 4Al = Al4C3

Al4C3 + 12H2O = 3CH4 + 4Al(OH)3

CH4 --[O]--> CH3OH

CH3OH + CuO = HCOH + Cu + H2O

HCOH + 2[Ag(NH3)2]OH = HCOOH + 2Ag + 4NH3 + 2H2O

2HCOOH + O2 = 2CO2 + 2H2O

1) 4al + 3c = al4c3

2) al4c3 + 12h2o → 3ch4 + 4al(oh)3

3) ch4 + cl2 (кат. квант света) → ch3cl + hcl

     ch3cl + naoh (кат. водн. р-р) → ch3oh + nacl

4) ch3oh + cuo → hcoh + cu + h2o

5) hcoh + ag2o (кат. nh3, h20) → hcooh + 2ag

5) 2hcooh + o2 → 2co2 + 2h2o
