Title:
METHOD FOR PRODUCING 2-ALKYL-3-NITROISOTHIOUREA
Document Type and Number:
Japanese Patent JP2003342253
Kind Code:
A
Abstract:
To provide a method for producing a 2-alkyl-3-nitroisothiourea useful as a raw material for agrochemicals from an S-alkylisothiourea in a high yield.
This method for producing the 2-alkyl-3-nitroisothiourea comprises reacting the S-alkylisothiourea with nitric acid in the presence of sulfuric acid. In the method for producing the 2-alkyl-3-nitroisothiourea, a reaction mixture is diluted with an aqueous solution of urea and the deposited product is recovered.
