概述羰基镍是由一氧化碳与镍反应制得,首先由英国的Mond(1890)发现,并应用于工业生产。羰基镍是一种无色透明的液体[分子式Ni(CO)_4],具有一种特殊的尘土气味(嗅阈为0.5 ppm),比重1.32,沸点43℃,在-25℃时凝结成针状结晶。室温下很容易挥发,25℃时的蒸气压为380mmHg。液体羰基镍溶于乙醇、苯和氯仿,难溶于水。它与碱和弱酸均不发生反应,遇浓盐酸也不分解,但遇硝酸及其它氧化剂很易 Overview Carbonyl nickel is produced by the reaction of carbon monoxide with nickel, first discovered by Mond (1890) in the United Kingdom and used in industrial production. Nickel carbonyl is a colorless and transparent liquid [Ni (CO) _4] with a special dusty odor (odor threshold of 0.5 ppm), specific gravity of 1.32, boiling point of 43 ° C and condensation to acicular form at -25 ° C crystallization. Very volatile at room temperature, vapor pressure at 25 ℃ 380mmHg. Liquid nickel carbonyl dissolved in ethanol, benzene and chloroform, insoluble in water. It does not react with alkali and weak acid, case of concentrated hydrochloric acid does not decompose, but when nitric acid and other oxidants are very easy
