Abstract
To provide an economically advantageous process for producing HFO-1234yf useful as a new refrigerant in sufficiently high yield by one reaction involving thermal decomposition. A process for producing HFO-1234yf and VdF from raw material containing R22, R40 and TFE, by a synthetic reaction involving thermal decomposition, which comprises (a) a step of supplying the R22, the R40 and the TFE to a reactor, as preliminarily mixed or separately, (b) a step of supplying a heat medium to the reactor, and (c) a step of bringing the heat medium in contact with the R22, the R40 and the TFE in the reactor to form the HFO-1234yf and the VdF.
