Title:
PROCESS FOR PRODUCTION OF O-METHYL-N-NITROISOUREA
Document Type and Number:
WIPO Patent Application WO/2007/091392
Kind Code:
A1
Abstract:
Disclosed is an industrially advantageous process for production of O-methyl-N-nitroisourea. O-methyl-N-nitroisourea of the formula (1) or a salt thereof can be produced in a high yield by performing the nitration of O-methylisourea of the formula (2) or a salt thereof with a nitrating agent in the presence of fuming sulfuric acid.
