羰基二异氰酸酯(1),最初是从热解1,3,5-三氯异氰尿酸的产品混合物中分离出来的。也有文献记载,由氯化锂及氯化钾在400℃熔融时,用氟碳酰氯与氰化钾的反应来合成羰基二异氰酸酯。另外,还有专利资料报道,用碳酰氯或氯甲酰基异氰酸酯,在三氯苯中煮沸时与1,3,5-三氯异氰尿酸反应,合成羰基二异氰酸酯,但该方法的缺点是产品分离困难。本文作者合成羰基二异氰酸酯的方法是:将克分子比为
Carbonyl diisocyanate (1) was initially isolated from the product mixture of pyrogenic 1,3,5-trichloroisocyanuric acid. It has also been documented that carbonyl diisocyanate is synthesized by the reaction of fluorocarbonyl chloride and potassium cyanide when molten lithium chloride and potassium chloride are melted at 400 ° C. In addition, there are also reports of patents that carbonyl carbonates or chloroformyl isocyanates react with 1,3,5-trichloroisocyanuric acid when boiled in trichlorobenzene to synthesize carbonyl diisocyanate, but the disadvantage of this method is that the product Difficult to separate. The author of the synthesis of carbonyl diisocyanate method is: the mole ratio of
