Process for the production of water-repellent, finely-divided inorganic compounds

Abstract: A process for imparting water-repellent properties to an inorganic compound which comprises treating said inorganic compound in a finely-divided form with from 1 to 20 percent by weight, based on the weight of said inorganic compound, of a compound having the formula R- COOR'' wherein R is the aliphatic remainder of a fatty acid having 10 to 26 carbon atoms and R'' is selected from the group consisting of hydrogen and alkyl having from one to four carbon atoms at a temperature of from 150* C. to 350* C., and recovering a waterrepellent inorganic compound.

Preparation of hydrocarbon-soluble molybdenum and vanadium compounds

Abstract: Molybdenum and vanadium salts of C5- 50 carboxylic acids, which salts are soluble in liquid hydrocarbons, are prepared by heating an oxalate group containing compound of molybdenum at valence + 6 or of vanadium at a valence + 5, with a C5- 50 carboxylic acid at a temperature of at least 140 DEG C. for at least 2 hours. The preferred oxalate compounds are those obtained by heating 0.5-1.2 mols. of an inorganic compound of Mo+6 or V+5 with 1 mol. oxalic acid in the presence of 0.5-50 parts by weight water ser part oxalic acid, using sufficient water to dissolve the Mo or V compound, at 100-150 DEG C. under a pressure sufficient to maintain a liquid phase, for 1-2.5 hours, and then removing the water. This reaction may be effected in the presence of the C5- 50 carboxylic acid. Molybdenum trioxide and vanadium pentoxide are the preferred inorganic compounds. It is preferred to use alkyl, alkenyl or aralkyl mono-carboxylic acids. Examples relate to the preparation of hexanoates, octanoates and naphthenates of Mo and V.
