Abstract: A method for preparing polyols such as diols by catalytic hydroxylation of an olefinic compound by reacting the olefinic compound with an organic hydroperoxide and water in the presence of a catalyst comprising osmium compound and a specific halide co-catalyst is disclosed.

Abstract: Novel rust inhibitors for hydrocarbon fuels and oils are provided. Also, novel photo-adducts of dimethylmaleic anhydride and olefins useful as rust inhibitors.

Abstract: In accordance with the present invention, there is provided a substituted cyclohexane-1,2-dicarboxylic anhydride (CHDA) having the structural formula: ##STR1##

Abstract: Compounds of the general formula: ##STR1## in which A is a benzene ring or a carbocyclic aromatic group consisting of two or three fused benzene rings, the group A being linked to the nitrogen containing ring at two adjacent carbon atoms and the benzene ring or each benzene ring optionally carrying one or more substituents which may be the same or different, and may be alkyl, aryl, halo, hydroxy, acyloxy or alkoxy, or two adjacent positions in a ring may be substituted so as to form a methylene dioxy group (--O--CH.sub.2 --O--);R.sub.1 and R.sub.2 which may be the same or different, each represent hydrogen; an alkyl group which contains 1 to 6 carbon atoms and which may be substituted; a hydroxycarbonyl or an alkoxycarbonyl group; andone of R.sub.3 and R.sub.4 represents hydrogen, an alkyl group which contains 1 to 6 carbon atoms and which may be substituted, or a hydroxy, alkoxy, hydroxycarbonyl or alkoxycarbonyl group and the other of R.sub.3 and R.sub.

Abstract: A normally solid Diels-Alder reaction product between maleic anhydride and decatriene can be liquefied by heat-treating at from 60.degree. to 250.degree. C. for from 10 minutes to 10 hours in the presence of a compound selected from the following groups (a) to (e):(a) alkali metal salts;(b) nitrogen atom-containing organic compounds;(c) phosphorus atom-containing compounds selected from phosphines and quaternary phosphonium salts;(d) thiocyanates; and(e) solid basic compounds.

Abstract: Halo-(carbonyldioxyaryl)ethylenes are prepared by a catalytic process which comprises contacting a halo-bis(hydroxyaryl)ethylene, carbon monoxide, an oxidant, a base, and a Group VIIIB element selected from ruthenium, rhodium, palladium, osmium, iridium or platinum. The resulting halo-(carbonyldioxyaryl)-ethylenes are useful as flame retardents for thermoplastic polymeric materials.
