Abstract: A process to prepare an improved fluid rare earth phosphate catalyst composition useful in preparing alkylene oxide adducts of organic compounds having active hydrogen atoms is provided. The catalyst is prepared by dissolving a rare earth salt in a C9-C30 active hydrogen containing organic compound and then adding phosphoric acid to the organic compound rare earth mixture.

Abstract: An olefin product rich in cis- or trans-isomers can be produced by reacting the mixed olefin feedstock with an linear polyaromatic compound such as anthracene under heat, then separating the unreacted olefin enriched in cis-isomer. The remaining linear unreacted polyaromtic compound and the polyaromatic compound-olefin adduct can be heated to dissociate the adduct to linear polyaromatic compound and olefin stream enriched in trans-isomer.

Abstract: A process for separating linear alpha olefins from a feedstock containing linear alpha olefins, saturated hydrocarbons, internal olefins, branched olefins, and alcohols, in particular, from a Fisher-Tropsch stream is provided.

Abstract: A detergent composition having cold water solubility and exhibiting high calcium tolerance can be produced from biodegradable branched ether derivative compositions derived from a branched ether primary alcohol represented by the formula: wherein R1 represents hydrogen or a hydrocarbyl radical having from 1 to 3 carbon atoms, R2 represents a hydrocarbyl radical having from 1 to 7 carbon atoms, x is a number ranging from 0 to 16, preferably from 3 to 13, wherein the total number of carbon atoms in the alcohol ranges from 9 to 24.

Abstract: A process for hydroxylating aliphatic compounds under catalytic distillation conditions to provide alcohols is provided. The aliphatic compound is contacted, in a distillation column reactor, with an oxidation catalyst and an oxidant under conditions effective to hydroxylate the aliphatic compound while maintaining at least a portion of the aliphatic compound in a liquid phase and separating the hydroxylated product from the un-reacted aliphatic compound in the distillation column reactor.

The hydrocracking catalyst comprises: a) from about 70 to about 90 weight percent of a Y zeolite, based on the catalyst having a silica to alumina mole ratio of from about 4.8 to less than 6.0, a unit cell constant within the range of about 24.50 to about 24.57, a Na2O level of less than or equal to about 0.2 weight percent; b) from about 10 to about 30 weight percent, based on the catalyst of an alumina having a mercury intrusion pore volume within the range from about 0.55 to about 0.85 cc/g; and c) from about 0.5 to 1 weight percent, based on the catalyst of a noble metal wherein said hydrocracking catalyst have a dispersivity of the noble metal of equal or greater than about 50% by hydrogen chemisorption measurement, a surface area of greater than or equal to 700 m2/g by BET surface area measurement, a compacted bulk density within the range of from about 0.40 to 0.

Abstract: A water-compatible curing agent for epoxy resins is prepared by (a) reacting at least one polyamine having at least 3 active amine hydrogen atoms per molecule and at least one epoxy resin in an epoxy equivalent to polyamine mole ratio of from 0.9:1 to 1:10 to obtain an amine-terminated intermediate; (b) reacting the amine-terminated intermediate with from 0.5 to 25 weight percent, based on the amine-terminated intermediate, of an acid-terminated polyalkylene glycol to yield an amine-terminated curing agent. The amine-terminated intermediate can be capped with a monoepoxide in an amine hydrogen atoms to epoxy groups ratio of from about 1.5:1 to 30:1 prior to reaction with the acid-terminated polyalkylene glycol, or the amine-terminated curing agent produced following step (b) can be capped with a monoepoxide.

Abstract: An epoxy resin composition containing a) an epoxy resin, b) a liquid amine terminated polyamine curing agent prepared by condensing an aminoalkylpiperazine and a dicarboxylic acid, and (c) water. An aqueous dispersion of the amine terminated polyamine curing agent used in this invention is useful as a curing agent for water borne applications.
