| titleOfInvention | Method for preparing chloroethylene monomer from dichloromethane |
| abstract | The invention discloses a method for preparing a chloroethylene monomer from dichloromethane. Under the condition of existence of a catalyst with hydrogenation activity, dichloromethane and hydrogen react to prepare the chloroethylene monomer; the reaction equation is 2CH2Cl2+H2=C2H3Cl+3HCl; the mole ratio of hydrogen to dichloromethane is (0.01-20) to 1; the reaction temperature of the reaction is 25-600 DEG C, and the reaction pressure is 0.001-10 atm. According to the method, raw materials are readily available and are low in cost, so that the production cost is low, and the reaction conversion rate is high; the chloroethylene monomer is high in selectivity; the method is a novel chloroethylene monomer synthesis technology and is suitable for being popularized and applied. |
