    • A process is provided for the stabilization of polychlorinated alkanes against dehydrochlorination. The process comprises adding a phenol compound to a polychlorinated alkane such that the dehydrochlorination of the polychlorinated alkane is suppressed when heated in the presence of iron(III). In a preferred embodiment, the process comprises the prevention or reduction of dehydrochlorination of 1,1,1,3,3-pentachloropropane when heated in the presence of iron(III) contamination by the addition of monomethyl ether hydroquinone. In another embodiment, the long term storage stability of polychlorinated alkanes against dehydrochlorination is improved due to the addition of a phenol compound.
    • 提供了一种用于稳定多氯代烷烃以防止脱氯化氢的方法。 该方法包括向多氯代烷烃中加入酚化合物,使得在铁(III)存在下加热时,抑制多氯代烷烃的脱氯化氢。 在优选的实施方案中,该方法包括当在加入单甲醚氢醌的铁(III)污染物存在下加热时,防止或减少1,1,1,3,3-五氯丙烷的脱氯化氢。 在另一个实施方案中,由于加入酚化合物,多氯代烷烃对脱氯化氢的长期保存稳定性得到改善。

    • A composition useful as a blowing agent having no flash point or reduced combustibility comprising 2-chloropropane and a gas selected from the group consisting of a fluorohydrocarbon, perfluorocarbons, fluoroethers, hydrofluoropolyethers and mixtures thereof is disclosed. A polyisocyanurate foam or a polyurethane modified polyisocyanurate foam having a mainly closed cell structure and also a method for preparing this foam, the latter comprising closed cells wherein a foam blowing agent consisting of a mixture of 2-chloropropane and one or more HFC compounds including pentafluoropropane, pentafluorobutane, heptafluoropropane, hexafluoropropane or pentafluoroethane are disclosed. Pentanes can be added if desired. Azeotropic mixtures in which 2­-chloropropane is an ingredient are disclosed.
