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.
提供了一种稳定多氯化烷防止脱氢氯化的工艺。该工艺包括向多氯化烷中添加苯酚化合物,从而抑制多氯化烷在铁(III)存在下加热时的脱氯化反应。在一个优选的实施方案中,该工艺包括通过添加单甲醚对苯二酚来防止或减少 1,1,1,3,3-五氯丙烷在有铁(III)污染的情况下加热时的脱氯化反应。在另一个实施方案中,由于添加了苯酚化合物,提高了多氯化烷的长期储存稳定性,防止脱氢氯化。
