Summary:A highly efficient and industrially advantageous process for producing 1,1,1,3,3-pentachloropropane (R240f) which comprises reacting carbon tetrachloride with vinyl chloride in the presence of a phosphoryl group-containing compound (phosphate ester, etc.) and an iron catalyst. The target product R240f is usable as a material for producing 1,1,1,3,3-pentafluoropropane (HFC245fa) expected as a foaming agent, etc. L'invention se rapporte à un procédé hautement efficace et avantageux d'un point de vue industriel, pour la production de 1,1,1,3,3-pentachloropropane (R240F). Ce procédé consiste à faire réagir du tétrachlorure de carbone avec du chlorure de vinyle en présence d'un composé contenant un groupe phosphoryle (ester de phosphate, etc.) et un catalyseur à base de fer. Le produit cible R240f peut être utilisé en tant que matière permettant la production de 1,1,1,3,3-pentafluoropropane (HFC245fa) destiné à constituer un agent gonflant, etc.
