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