Abstract
This invention relates to a process for preparing 2-methyl-2-(methylsulfonyl) propionaldehyde O-(methylcarbamoyl) oxime as an aqueous wet cake by reacting 2-methyl-2-(methylthio) propionaldehyde oxime with methyl isocyanate in an aqueous medium to give 2-methyl-2-(methylthio) propionaldehyde O-(methylcarbamoyl) oxime which is then oxidized in an aqueous medium to give 2-methyl-2-(methylsulfonyl) propionaldehyde O-(methylcarbamoyl) oxime. This invention also relates to an aqueous wet cake composition containing 2-methyl-2-(methylsulfonyl) propionaldehyde O-(methylcarbamoyl) oxime.
