Abstract: The invention relates to compositions of ?,?-branched alkane carboxylic acids glycidyl esters which derived from rosin and or hydrogenated rosin reacted with an epihalohydrin. The above glycidyl esters compositions can be used for example, as monomer in binder compositions for paints or adhesives, as reactive diluent or as acid scavenger. This invention is also about the uses of rosin and or hydrogenated rosin glycidyl ester in combinations with polyester polyols, or acrylic polyols, or polyether polyols.

Abstract: Methods and compositions are provided for the manufacture of an epoxide. In one embodiment, the invention provides a process for the manufacture of an epoxide including providing an olefin, an oxidant, alkaline earth metal ions, a catalyst component, a buffer component, and water to form a reaction mixture and reacting the olefin with the oxidant in the reaction mixture.

Abstract: The invention relates to a process for purification of epichlorohydrin containing 1,2-epoxy-5-hexene impurity, by (a) epoxidizing allyl chloride contaminated with 1,5-hexadiene into epichlorohydrin, (b) removing any unreacted allyl chloride, (c) adding a halogen to the crude epichlorohydrin obtained after the removal of unreacted allyl chloride and allowing the halogen to react with 1,2-epoxy-5-hexene and other olefinically unsaturated components, if any, in the crude epichlorohydrin, and (d) rectifying the product of step (c) to obtain epichlorohydrin, wherein the amount of halogen added in step (c) is at a molar ratio of at least 0.5:1 to less than 1:1 calculated on the amount of said 1,2-epoxy-5-hexene and said other olefinically unsaturated components in the crude epichlorohydrin, and allowing the halogen to react until it is fully converted.

Abstract: The invention provides a process for the preparation of an allyl alkyl ether comprising the allylation of an aliphatic hydroxyl containing compound with an allyl source in the presence of a catalyst, wherein the catalyst is a transition metal complex with a phosphine ligand, wherein the allylation is carried out in the presence of an acid in an amount of at least 0.1 mol % calculated on the aliphatic hydroxyl containing compound. This invention further provides a process for the preparation of epoxy resins wherein as intermediate use is made of the allyl alkyl ethers prepared by the process of the invention.
