    摘要： A solvent system employed in the preparation of phenylene diisocyanates in high yields and purity from phenylene di(nitrile sulfites) wherein the nitrile sulfite groups are either meta or para to each other, is disclosed. The solvents employed are paraffinic hydrocarbons often having about 4 to 16 carbon atoms. Solvent recycle is advantageously employed in the decomposition of, for instance, benzene-1,4-di(nitrile) sulfite) to improve product yield without decreasing purity.
