异丁烷

异丁烷用途

用途一：主要用于与异丁烯经烃化而制异辛烷，作为汽油辛烷值的改进剂，也可用作冷冻剂
用途二：主要用作石化企业分析、检测仪器的标准气
用途三：气溶胶；充气剂。
用途四：主要用于与异丁烯经烃化生产异辛烷，用作汽油辛烷值改进剂。经裂解可制异丁烯与丙烯。与异丁烯、丙烯进行烷基化可制烷基化汽油。可制备甲基丙烯酸、丙酮和甲醇等。还可作冷冻剂。

异丁烷制备

1.存在于石油气、天然气和裂化气中。由石油裂化过程中产生的碳四馏分，经分离而得。

2.以工业异丁烷为原料（含量为82%～91%），采用三级吸附工艺。一级吸附器脱除Ｃ２、Ｃ３、正丁烷和1-丁烯等杂质，二级吸附器除去异丁烯，在三级吸附器中进一步除去Ｃ２、Ｃ３烃类杂质，产品纯度大于99.99%。
