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.

• 用途一:光气是一种重要的有机中间体，在农药、当杰医药、工程塑料、聚氨酯材料以及军事上都有许多用途。在农药生产中，用于合成氨基甲酸酯类杀虫剂西维因、速灭威、叶蝉散等许多品种，还用于生产杀菌剂多菌灵及多种除草剂，我国临湘氨基化学品厂和宁阳农药厂已成为氨基甲酸酯类农药的生产基地，宁阳家药厂已能生产43个品种。以光气为原料生产的异氰酸酯类产品，例如TDI，MDI，PAPI是聚氨酯硬泡、软泡、弹性体、人造革的重要原料；有些品种的异氰酸酯，大量用于聚氨酯涂料；也有的特殊品种用于粘结剂，例如列克纳胶。在染料工业中用于生产猩红酸等染料中间体，在国防工业中用于生产中定剂二甲基二苯脲和作为军用毒气。用光气生产的氯代甲酸酯类是农药、医药、聚合引发剂等有机合成的中间体。用光气直接法或酯交换法生产工程塑料聚碳酸酯时，都需要光气作原料。光气剧毒，是一种强刺激、窒息性气体。吸入光气引起肺水肿、肺炎等，具有致死危险。

• 方法一:当需要少量光气时，可将四氯化碳与硫酸反应。将四氯化碳加热至55-60℃，滴加入发烟硫酸，即发生逸出光气，如需使用液态光气，则将发生的光气加以冷凝。工业上通常采用一氧化碳与氯气的反应得到光气。这是一个强烈放热的反应，装有活性炭的合成器应有水冷却夹套，控制反应温度200℃左右。为了获得高质量的光气和减少设备的腐蚀，经过彻底干燥的一氧化碳在与氯气混合时，应保持适当过量。将混合气从合成器上部通入，经过活性炭层后，很快转化为光气。当选用规格为Ф700×2900的合成器时，每台可年产光气200t。原料消耗定额：氯气（＞99%）925kg/t、氧气（标准状况下）268（m3）kg/t、焦炭400kg/t。
