Abstract
(1) In the reaction between chlorine and ethylene chloride in the liquid phase 1,1,2,-trichlorethane is the principal product and in the gaseous phase the formation of hexachlorethane predominates. (2) The reaction between gaseous chlorine and liquid ethylene chloride seems to occur mainly on the liquid gas interface. (3) Hydrogen chloride gas dissolved in the mixture catalytically accelerates the reaction. (4) There seems to exist an induction period in the reaction between ethylene chloride and chlorine possibly owing to catalytic acceleration by either hydrogen chloride or substituted product or both in later stage. (5) In the gaseous reaction between chlorine and ethylene chloride the formation of hexachlorethane predominates especially when chlorine exists largely in excess to ethylene chloride vapour. (6) A suggestion is made as to the method of study on chemical reactions, especially on chlorination reaction (substitution).
