Title:
PROCESS FOR PREPARING ORGANIC ISOCYANATES
Document Type and Number:
Japanese Patent JPS52122306
Kind Code:
A
Abstract:
Process for the preparation of organic isocyanates in which a furoxan is heated in the presence of a vicinal diketo compound containing two adjacent keto carbonyl groups. When the furoxan ring is fused to an organic ring system di-isocyanates are produced. An adduct of the furoxan and the diketo compound may be isolated from the reaction mixture and used as a stable isocyanate precursor, for example, a "one-pot" polyurethane composition.
