9.1 Introduction Chlorohydrocarbons are the main product of the chlorination process. Chlorohydrocarbons means the chlorinated compounds of hydrocarbons, that is, the compounds generated by substituting one or more, even if all hydrogen atoms in aliphatic hydrocarbons, alicyclic hydrocarbons and aromatics. Important industrial chlorinated aliphatic hydrocarbons: Vinyl chloride, 1,2 - dichloroethane, dichloroethylene, Chloromethane, dichloromethane, chloroform Carbon tetrachloride
9.2 Main production methods of chlorinated hydrocarbon一Substituted chlorinationCH4 + Cl2CHC1 + HClCH>CH=CH2 + HC1CH3CH=CH2 + Cl2+HClCl2
9.2 Main production methods of chlorinated hydrocarbon 一、Substituted chlorination
二、AdditionchlorinationCH2=CH2 + Cl2 →C1CH2CH2C1CH=CH + Cl2 -→ CHCI-CHCI三、Hydrochlorination reaction氢氯化反应→ CH,=CHC1CH=CH +HC1CH,CH=CH2. +HOC1*CH3-CH-CH2一一OH C1
二、Addition chlorination 三、Hydrochlorination reaction (氢氯化反应 ) CH≡CH + Cl2 → CHCl=CHCl
四，Dehydrochlorination reactionCH2C1-CH2C1 → CH2=CHCI + HCICHCI2CHC -→ CHCI-CC + HCI五、Oxychlorinationreactions（氧氯化反应CuCl2CICH,CH,Cl + H20CH>=CH2 + 2HC1 + 1/2O2HC1+1/202+H20
四、Dehydrochlorination reaction CH2Cl-CH2Cl → CH2=CHCl + HCl CHCl2CHCl2 → CHCl=CCl2 + HCl 五、Oxychlorination reactions (氧氯化反应 )
