Abstract
An improved process for preparing dihydrocarbyl substituted dithiocarbamates of molybdenum (VI) wherein an alkali metal ammonium or substituted ammonium salt of a dihydrocarbyl substituted dithiocarbamate is reacted with an alkali metal molybdate in the presence of an organic acid. The process is carried out in an inert atmosphere and within a relatively narrow range of temperatures. The dihydrocarbyl substituted dithiocarbamate of molybdenum (VI) may be recrystallized after preparation to increase its purity. The dihydrocarbyl substituted dithiocarbamate of molybdenum (VI) is produced at a temperature within the range from about -10.degree. C. to about +25.degree. C. at a pH during neutralization within the range from about 5.0 to about 8.0.
