Isobutane, also known as i-butane, 2-methylpropane or methylpropane, is a chemical compound with molecular formula HC (CH 3) 3. It is an isomer of butane. Isobutane is a colorless, odorless gas. It is the simplest alkane with a tertiary carbon atom.

异丁烷，又名2-甲基丙烷，是一种有机化合物，化学式是C4H10，常温常压下为无色可燃性气体。 微溶于水，可溶于乙醇、乙醚等，与空气形成爆炸性混合物，主要存在于天然气、炼厂气和裂解气中，经物理分离获得，主要用于与异丁烯经烃化制异辛烷，作为汽油辛烷值的改进剂，也可用作冷 …

异丁烷 （IUPAC命名 2-甲基丙烷，又称 甲基丙烷）是一种 烷烃，与（正） 丁烷 互为 同分异构体。 由于近年来人们对 氟利昂 引起的 臭氧层 破坏问题的关注，异丁烷作为氟利昂的替代品，使用逐渐增加。 异丁烷可用作家用 冰箱 和 冰柜 中的 制冷剂，也可用作 喷雾器 中的压缩气体。 异丁烷作为制冷剂时的编号是 R600a。 IUPAC在1993年推荐使用傳統的「异丁烷」名称，但在2013年時改為2-甲基丙烷。 因為2號碳是丙烷中唯一能接上甲基而不改變主鏈的碳，所以也常省略「2- …

butane, either of two colourless, odourless, gaseous hydrocarbons (compounds of carbon and hydrogen), members of the series of paraffinic hydrocarbons. Their chemical formula is C 4 H 10. The compound in which the carbon atoms are linked in a straight chain is denoted normal butane, or n -butane; the branched-chain form is isobutane.

2 天之前 · In this study, it was aimed to enrich the feed stream in the FCC (Fluid Catalytic Cracking) unit outlet by isobutane dehydrogenation. A gas mixture consisting of 15 mol% isobutane, 15 mol% isobutene, 15 mol% hydrogen, and 55 mol% helium was used as the feed stream. Reactions were performed in a fixed bed reactor system containing a Pd alloy membrane by creating a pressure difference of 70 kPa ...
