overview

compound introduction

二异丁烯是一种无环烯烃。由 2,4,4-三甲基-1-戊烯和 2,4,4-三甲基-2-戊烯(二异丁烯的同分异构体)的混合物组成。与异辛烷同构。可由叔丁醇合成。 二异丁烯是一种烯烃,可用于以下研究: · 合成代用柴油。 · 作为单缸发动机的燃料;据研究报道,燃料燃烧产生的废气含有高浓度的烯烃。 · 单、双烷基化二苯胺的制备。 Diisobutylene is an acyclic alkene. It is composed of a mixture of 2,4,4-trimethyl-1-pentene and 2,4,4- trimethyl-2-pentene (isomeric forms of diisobutylene). It is isostructural to to iso-octane.It can be synthesized from tertiary butyl alcohol. Diisobutylene, an alkene, may be used in the following studies: · To compose alternalte diesel fuel. · As fuel in single-cylinder engine; exhaust generated from combustion due to the burning of fuel has been reported to contain high concentrations of olefins. · Preparation of mono- and dialkylated diphenylamines.
