а)Гидрирование
1)С2H2+H2 ==>C2H4 (кат. Ni,t )
2)C2H4+H2==>C2H6 (кат. Ni ,t )
б)Галогенирование
(Качественная реакция на алкины)
С2H2+Br2(р-р)==>C2H2Br2
C2H2Br2+Br2(р-р)==>C2H2Br4
в)Гидрогалогенирование
С2H2+HCl==>C2H3Cl (винилхлорид)
г)Гидратация (реакция Кучерова)
С2H2+H2O==>CH3-COH (кат. соли ртути двухвалентные)
д)Полимеризация
1)димеризация
С2H2+C2H2==>C4H6 (бутадиен- 1,3)
2)тримеризация3
С2H2==>C6H6 (кат. акт. уголь t = 600 градусов)
Р-я Замещения
С2H2+Ag2O==>C2Ag2 (в осадке) +H2O
Р-я Горения
2С2H2+5O2==>4CO2+2H2O
