Claims5
A process for producing 1,1,2-trichloroethane, comprising a step of
- obtaining a product containing 1,1,2-trichloroethane by an addition reaction of a dissolved vinyl chloride monomer and dissolved chlorine in contact with each other under a liquid medium comprising a chlorinated hydrocarbon-based solvent and iron(III) chloride as a catalyst suspended therein,
- wherein the step is carried out in a reaction unit comprising a gas-lift type of bubble column through which the liquid medium is circulated without a separate pump by gas containing the dissolved vinyl chloride monomer and dissolved chlorine and an external down-comer which circulates the gas and liquid medium out of the bubble column,
- wherein the addition reaction takes place in both the bubble column and the external down-corner,
- wherein the vinyl chloride monomer and chlorine are respectively supplied to a section in which the liquid medium rises in the gas-lift type of bubble column,
- wherein the step is carried out at a reaction temperature of 25 to 80° C.
