A process for the catalyzed conversion of wet acetylene-containing streams to an essentially aromatic product rich in aromatic compounds, particularly benzene, toluene and styrenes using a promoted catalyst composition made by incorporating a major amount of a HAMS-1B crystalline borosilicate molecular sieve composited in an inorganic matrix with a minor amount of a zinc compound and calcining the result to form a promoted catalyst composition containing supported zinc oxide.

Process for converting a wet acetylene-containing stream to aromatics

Catalysts containing a reducible compound on a silica-containing support are provided for the conversion of a lower molecular weight alkane to more valuable, higher molecular weight hydrocarbons.

Catalysts for conversion of a lower alkane

The catalyzed oxidative coupling of a lower molecular weight alkane to more valuable, higher molecular weight hydrocarbons and oxidative coupling catalysts for use therein are disclosed.

Conversion of a lower alkane

Di-substituted maleic anhydride compounds are disclosed of the structural formula ##STR1## wherein R and R.sup.1 are selected from the group consisting of aliphatic and phenyl moieties, and R.sup.2 is a divalent aromatic moiety. Polyamide-imide polymers, polyimide polymers and vinyl copolymers derived therefrom are also disclosed.

Disubstituted maleic anhydride compounds

A process for hydration and condensation of acetylene in a crude acetylene stream containing water in the presence of a zirconia-alumina catalyst containing water to prepare aliphatic, aromatic and oxygenated compounds suitable for use as high octane liquid water fuels and as octane improvers for motor fuels is disclosed.

Process for preparation of fuel additives from acetylene

Quaternary ammonium compounds containing an anhydride groups are prepared by halogenating dimethylmaleic anhydride and reacting the halogenated product with a tertiary amine. The products are useful as surfactants, biocides and as cosurfactants in enhanced oil recovery.

Quaternary ammonium compounds containing an anhydride group

Cyclic dianhydrides and polyimides are prepared from maleic anhydride compounds and diolefins. The diolefins are alpha- , omega-linear diolefins of up to 100 carbon atoms or cyclic diolefins of up to 40 carbon atoms. The polyimides and copolyimides prepared from these cyclic dianhydrides are useful in films, fibers and coatings.
