    摘要： Alkylene diisocyanates of the formula OCN-R-NCO are prepared by heating a compound of the formula ##EQU1## at a temperature of about 200.degree. to about 500.degree. C. wherein --R-- is dimethylene, trimethylene or tetramethylene which may bear lower alkyl substituents. For example, ethylene diisocyanate is prepared by heating ethylene urea N,N'-dicarbonyl chloride at about 350.degree.C.

    摘要翻译： 式OCN-R-NCO的亚烷基二异氰酸酯是通过在约200℃至约500℃的温度下加热下式的化合物和平行的平行并联ClC-NCN-CCl R来制备的。其中-R-是二亚甲基，三亚甲基 或可含有低级烷基取代基的四亚甲基。 例如，通过在约350℃下加热亚乙基脲N，N'-二羰基氯来制备亚乙基二异氰酸酯
