    摘要: Novel polyimides, copolyimides and molding compositions are prepared from novel dianhydrides such as tricyclo[6.4.0.0.sup.2,7 ] dodecane-3,6-diphenyl-1,8,4,5-tetracarboxylic acid dianhydride and tricyclo[6.4.0.0.sup.2,7 ] dodecane-1,8,4,5-tetracarboxylic acid dianhydride. The novel polyimides are useful as engineering plastics. The novel dianhydrides are useful for the preparation of the polyimides. Other dianhydrides can be mixed with our novel dianhydrides to make novel copolyimides useful as engineering plastics.

    摘要: Trifluoromethylsulfonic acid has been found to be an extremely useful catalyst for the manufacture of mercaptans from olefins or viscous polyolefins and hydrogen sulfide. Also a novel process for the preparation of mercaptans is disclosed which proven comprises reacting olefins or polyolefins at a temperature of about -10.degree. to 70.degree. C. with hydrogen sulfide under pressure of about 1 to 10 atmospheres in the presence of about 0.05 to 10 percent by weight of the olefins of the trifluoromethylsulfonic acid. The mercaptans produced according to the novel process are useful in the preparation of nonionic surfactants for lubricating oils and in the enhanced oil recovery as well as for biocides. Novel beta-polybutenylsulfoxy-alpha-hydroxyethylbenzenes have also been prepared. These are useful in the preparation of nonionic surfactants for lubricating oils and as biocides.

    摘要: This invention relates to a new catalyst and to a novel oxidation process. In this novel process, aromatic compounds with an alkyl group having at least one alpha hydrogen, including aromatic compounds wherein the alkyl groups are unsubstituted and substituted, are contacted in the liquid phase at reaction conditions with an oxygen-containing gas in the presence of a novel catalyst which is prepared by milling an anhydrous transition metal halide with silver nitrite, the transition metal being selected from the Groups IVb to VIII and IIb of the Periodic Table, wherein the mole ratios of metal halide to silver nitrite are in the ratio of 1:1 to 1:5.
