氯代烷在脂族化合物的合成中,是重要的起始原料。但是它们的制备,特别是长链伯位氯代烷的制备,虽然有许多方法,但由于原料不易得,或由于产物纯度不高(含有异构体),而步骤又较繁多,限制了它的研究和应用.这也就限制了长链烷烃各种取代化合物的研究与应用。 作者等曾发现了一种新的伯位氯代烷的制备方法。即以烷烃在与100％硫酸搅拌时进行光照通氯,得到伯位取代物。此法产率虽然不高,但方法简便,产物纯度高,不含仲位异构
Chloroalkanes are important starting materials in the synthesis of aliphatic compounds. However, their preparation, especially the preparation of long-chain primary alkanes chlorinated alkanes, although there are many methods, it is limited because it is not easy to obtain raw materials or due to the low purity of the products (including isomers) and the numerous steps Of the research and application.This also limits the long-chain alkanes various substituted compounds research and application. The authors have found a new method for preparing primary alkanes. That is, when alkanes are chlorinated with 100% sulfuric acid while stirring, primary substitutes are obtained. Although the yield of this method is not high, but the method is simple, the product of high purity, excluding meta-metaomerism
