    Abstract: A process for treating a pyrophoric P₄-containing material to convert it to a substantially non-pyrophoric P₂O₅ material is described. The process comprises supplying streams of fluid P₄-containing material and an oxygen-­containing gas to a reactor filled with water. The P₄-­containing material and the oxygen and the oxygen-containing gas react with one another after both have entered the aqueous medium within the reactor to thereby form the desired P₂O₅ material.

    Abstract: Process for the production of fatty acids by oxidative dehydrogenation of straight or branch chain primary alcohols of from C-4 to C-30 chain lengths per molecule, or mixtures of branch and straight chains, which are selectively reacted with an anhydrous alkali metal hydroxide. In the reaction, the temperature of reaction is gradually increased to maintain the reaction medium in a liquid non-viscous state. The reaction temperature is, however, maintained at a sufficiently low temperature to minimize by-product formation. The process is conducted at temperatures of from about 175°C to about 400°C for sufficient time to form the sodium salt of the acid which is then converted to the acid utilizing a mineral acid.

    Abstract: Isothiocyanates are formed by oxidizing, with gaseous oxygen or air, in the presence of a metal oxidation catalyst a dithiocarbamate with appropriate control of the pH of the reaction medium to suppress the formation of by-products. Optionally a quaternary ammonium halide catalyst can be used to increase product yield.

    Abstract: Lipase hydrolysis of an ester group of a substrate can be conducted in the absence of large quantities of water and excess enzyme without extensive inhibition of enzyme activity due to water-soluble product alcohol. A lipase reaction can be efficiently conducted by dispersing a water-­immiscible organic substrate phase in an aqueous phase, washing the reaction continuously while the reaction mixture is maintained in the dispersed state, and continuously removing an amount of aqueous phase substantially equivalent to the washing solution added. The washing solution can be an aqueous neutralizing solution. By this process, water-­soluble product alcohol can be removed from the reaction mixture without removal of substantial quantities of water-­soluble enzyme.
