    摘要: The present invention provides polyunsaturated fatty acid compounds having antimalarial and/or neutrophil stimulatory activity. The polyunsaturated fatty acids contain 18-25 carbons and 1-6 double bonds and are characterized in that they have one or two substitutions selected from the group consisting of &bgr; oxa, &ggr; oxa, &bgr; thia and &ggr; thia. It is also preferred that the polyunsaturated fatty acid compound includes a further substitution selected from the group consisting of hydroxy, hydroperoxy, peroxy, carboxymethyl substitutions or attached to an amino acid. The invention also provides a method of producing an unsaturated oxa substituted fatty acid comprising reacting an unsaturated fatty acid alcohol with a carbene that is inserted in the OH bond of the alcohol, the invention further provides a method of treating inflammation with a composition comprising at least one hydroxy, hydroperoxy or peroxy derivative of a polyunsaturated fatty acid having a C18-24 carbon chain and 1-6 cis or trans double bonds.

    摘要: 2,5-dimethyl-2,5-di-t-butylperoxy-hexane is produced by reacting 2,5-dimethyl-1,5-hexadiene with t-butylhydroperoxide under acid catalysis in the presence of an electron pair acceptor Lewis acid in a substantially anhydrous solvent. If one uses technical water-containing t-butylhydroperoxide, the water can be separated, after mixing with the 2,5-dimethyl-1,5-hexadiene, by adding sulfuric acid or calcium chloride and subsequently the electron pair acceptor Lewis acid is added.

    摘要: Blends of meta and para isomers of .alpha., .alpha.'-bis(t-butylperoxy) diisopropylbenzene are disclosed as well as methods of producing blends of .alpha., .alpha.'-bis(t-butylperoxy) diisopropylbenzene with desired ratios of meta and para isomers.Additionally, blends of meta and para isomers of .alpha., .alpha.'-bis(t-butylperoxy) diisopropylbenzene and tertiary alkyl cumyl peroxides are disclosed.The peroxides are useful for absorbing in polymers and subsequently crosslinking the polymers. The peroxide blends may be adjusted to have melt points below temperatures at which the polymers become difficult to process during the absorption step because of stickiness.
