Editor: Hüttner, W.

Abstract: Volume II/19 Molecular Constants mostly from Microwave, Molecular Beam and Sub-Doppler Laser Spectroscopy is a supplement to the earlier volumes II/4, II/6, and II/14. The slight change in the title reflects current trends in the applications of spectroscopic methods. Together, the four volumes collect all the critically evaluated data published up to 1989/90 on constants of free molecules obtained by classical and modern spectroscopy. Volume II/19 is divided into four parts to record the growing number of investigations, especially in the microwave and millimeter wave regions, where modern techniques like Fourier Transform Microwave Spectroscopy have made new objects of interest such as molecular complexes and clusters accessible to study. Subvolume II/19b contains corresponding data on diamagnetic asymmetric top molecules.

• 概述:一种气体烷烃，分子式C4H10。存在于石油和天然气中。有直链的正丁烷和支链的异丁烷两种异构体。二者在常温常压下均为无色可燃性气体。 正丁烷又称丁烷，相对密度0.6012(0℃)、0.5788。熔点-138.4℃。沸点-0.5℃。临界温度 152.01℃。临界压力3.797MPa。闪点-60℃。折射率1.3259(液体，在饱和压力下)、1.0013(气体，在常压下)。溶于乙醇(17℃及10.332×103Pa时， 18ml/1ml)、乙醚(25ml/1ml)、氯仿(30ml/1ml)，微溶于水(0.5ml/1ml)。与空气形成爆炸混合物，爆炸极限1.6%～8.5%(体积分数)。 异丁烷又称2-甲基丙烷。相对密度0.5510 (25℃)。熔点-159.4℃。沸点-11.7℃。临界温度134.98℃。临界压力3.65MPa。折射率1.3508 (液体，在饱和压力下)。闪点-83.6℃。燃点 420℃。微溶于水(40℃时0.005ml/100ml)，溶于乙醇(17℃时1346ml/100ml)、乙醚(18℃时2839ml/100ml)。与空气形成爆炸混合物，爆炸极限1.9%～8.4%(体积分数)。 丁烷在催化剂存在下去氢,生成丁烯(1-丁烯和2-丁烯)或丁二烯,在硫酸或无水氢氟酸存在下异构化为异丁烷。异丁烷催化去氢，生成异丁烯(CH3)2C＝CH2；异丁烷可作为烃化剂与烯烃反应，生成抗爆性能好的支链烷烃，例如,与异丁烯反应生成异辛烷（见辛烷、辛烷值）。 炼油工业中用裂解法生产汽油时生成大量正丁烷，与丙烷和少量乙烷一起液化后作为燃料,即液化石油气,也用作溶剂和化工原料。
