Abstract: High-temperature resistant sulfonated aromatic polyether ketone cation exchangers and sulfonated poly(phenylene sulfide) cation exchangers are revealed as catalysts for various reactions at reaction temperatures above 150° C. The invention relates to the use of sulfonated aromatic polyether ketone cation exchangers and sulfonated poly(phenylene sulfide) cation exchangers as catalysts for such reactions. The preferred reaction is esterification to make octyl palmitate.

Abstract: The present invention relates to a method of triboelectric separation of organic polymers and salts, specially organic polymers containing sulfur, such as polyarylene sulfides and a halogenide or a carboxylate of alkaline metals, alkaline earth metals, ammonium or substituted ammonium wherein: a) the mixture to be separated is electrically charged; b) the charged particles are moved by an electric field, preferably perpendicular to the direction of the field, and c) the particles varyingly deviated in the electric field are separated and captured.

Abstract: Disclosed and claimed is a process for selectively separating hydrogen halides from sulfur-dioxide-containing gases by using an adsorbent made from a porous ceramic support material which is impregnated with an alkaline earth metal salt solution and, after evaporation of the solvent, the alkaline earth metal salt is pyrolysed at 200.degree. to 800.degree. C. to give alkaline earth metal oxide .Xh.sub.2 O, where x is a number from 0 to 1.

Abstract: The invention relates to a process for eliminating adsorbable organic halogen compounds from an aqueous phase, in particular from wastewater or from a process solution, in which the aqueous phase is treated with a nonaqueous extraction medium in a liquid-liquid extraction, which comprises, after the extraction, subjecting the adsorbable organic halogen compounds in the extraction medium to a Wurtz-Fittig reaction. Only small amounts of noncritical products such as NaOH and Hcl, which can be readily removed, are formed in the nonaqueous extraction medium. By means of this process, the cost of the chemicals which conventionally arises in the elimination of the adsorbable organic halogen compounds is considerably decreased.

Abstract: Heating of polyvinyl chloride, in particular plasticizer-containing polyvinyl chloride, to a temperature of from 250.degree. to 500.degree. C. in the absence of oxygen gives a low-chlorine, carbon-containing residue, plasticizer and hydrogen chloride.

Abstract: In isolating fullerenes from fullerene-containing soot the soot is heated by using microwaves to from 300.degree. to 800.degree. C. and the evaporating fullerenes are condensed.
