Abstract
Tolylene diisocyanate is a more important organic compound, and by-products always be produced during its production. It is necessary to determine the structure of the by-product, for the research of the reaction mechanism and reaction condition. A method is described whereby the structure of the byproducts, especially the substitute radical can be determined by 1H, 13C and HMBC spectrum.
