Title:
METHOD FOR PRODUCING TRIFLUOROETHYLENE
Document Type and Number:
WIPO Patent Application WO/2014/208452
Kind Code:
A1
Abstract:
Provided is an economically advantageous method for efficiently and at a high purity producing HFO-1123, which is industrially useful, by means of a synthesis reaction that uses easily acquired starting materials, does not use a catalyst, and accompanies pyrolysis, in a manner such that the generation is suppressed of by-products difficult to separate by means of distillation from HFO-1123, particularly HFO-1132(E). The method produces HFO-1123 from TFE and R31 by means of a synthesis reaction accompanying pyrolysis, and has (a) a step for supplying TFE and R31 to a reaction vessel separately or in a pre-mixed manner, (b) a step for supplying a heat medium to the reaction vessel, and (c) a step for generating trifluoroethylene by contacting the tetrafluoroethylene, chlorofluoromethane, and heat medium together in the reaction vessel in the state of the temperature of the interior of the reaction vessel being controlled to 400-950°C.
