Abstract: Wastes from chemical processes contg. halogens and/or hydrogen halides and elemental carbon and/or a heavy organic residue and opt. water are reacted with oxygen or an O2-contg. gas at 300-700 degrees C in the presence of a catalyst system comprising V2O5 and an oxygen-contg. cpd. of P(V) on an inorganic carrier (having a specific surface area of 250-600 m2/g). The halogens and/or the hydrogen halides are sepd. from the gaseous reaction prods. by condensation or absorption in water. CO2 is released to the atmos. Complete combustion of carbon is achieved. The economy of the process is good because the fuel consumption is less than in the known processes.

Abstract: A process for separating toluene diisocyanate and/or higher boiling solvents from distillation residues obtained from the phosgenation of toluene diamine in the presence of solvents wherein the separation takes place in a fluidized bed at temperatures of 140 DEG C. to 280 DEG C.

Abstract: Diacetates of 1,2-glycols are manufactured by reacting acetic acid with an olefin and oxygen, using oxygen dissolved in the liquid phase of the reaction mixture and avoiding the presence of gaseous oxygen in the reaction space.
