(525d) One-Step Process for the Production of 1,1,3,3-Tetrachloropropene

Hydroclurocarbon (HFC) products are widely utilized in many applications, including refrigeration, foam expansion, and as propellants for aerosol products.  HFC is being phased out with Hydrofluoroolefins (HFO) such as  1,3,3,3-tetrafluororopene (HFO-1234ze) to meet the expected higher standard  environmental impact.  This HFO has properties that meet European requirements of low global warming potential and no impact on the ozone layer.   HFO-1234ze can be produced from 1,1,3,3-tetrachloropropane (TCPe).  In this work,  a one-step process is proposed to produce TCPe from readily available trichloroethylene and methylene chloride.
