烷基化

烷基化是烷基由一个分子转移到另一个分子的过程。近现代产业中,在整个炼油过程中,烷基化可以将分子按照需要重组,增加产量,对油品应用是非常重要的一环。

以标准的炼油过程来做说明,烷基化系统在催化剂(磺酸或者氢氟酸)的作用下,将低分子量烯烃(主要由丙烯和丁烯组成)与异丁烷结合起来,形成烷基化物(主要由高级异辛烷,侧链烷烃组成)。烷基化物是一种汽油添加剂,具有抗爆作用并且燃烧后产生清洁的产物。烷基化物的辛烷值由所用的烯烃种类和采用的反应条件有关。

Alkylation 烷基化

Benzene Friedel-Crafts alkylation.
Alquilación del benceno Friedel-Crafts.

Alkylation is the transfer of an alkyl group from one molecule to another. The alkyl group may be transferred as an alkyl carbocation, a free radical, a carbanion or a carbene (or their equivalents). An alkyl group is a piece of a molecule with the general formula CnH2n+1, where n is the integer depicting the number of carbons linked together. For example, a methyl group (n = 1, CH3) is a fragment of a methane molecule (CH4). Alkylating agents utilize selective alkylation by adding the desired aliphatic carbon chain to the previously chosen starting molecule. This is one of many known chemical syntheses. Alkyl groups can also be removed in a process known as dealkylation.
