标 题 :Solventless preparation of phthalimides
发明人:NICK ROBERT JOSEPH; NELSON MARK ERIK; CARINGI JOSEPH JOHN; WILLIAMS DREW ELLIOT
权利人:GEN ELECTRIC
摘要:A method for the solventless synthesis of a phthalimide or phthalimide mixture is provided comprising contacting at least one amine reactant and at least one anhydride reactant in a solventless environment at a first temperature sufficient to allow the reactants to at least partially condense; and increasing the temperature to a second temperature sufficient to melt the reaction mixture, thereby allowing the reaction to go essentially to completion and form the reaction product.

标题 :Aliphatic polyimides from a 1:2 molar ration of diamine and unsaturated monoanhydride or unsaturated diacid
发明人:DUAN YANNAN; AVAKIAN ROGER W
权利人:POLYONE CORP
摘要:Aliphatic polyimides are synthesized by a 2:1 molar ratio reaction of an unsaturated monoanhydride or an unsaturated diacid with a diamine. Bio-derived monomers are particularly useful in the synthesis of the aliphatic polyimides.

标题:Process for recovering an optically active epoxy alcohol
发明人:SHIH T THOMAS; SHUM WILFRED P-S
权利人:ARCO CHEM TECH
摘要:A method of recovering optically active epoxy alcohols from asymmetric epoxidation reaction mixture is provided whereby the epoxy alcohol may be obtained in high yield with minimal degradation of optical purity. The process is also suitable for the synthesis of useful organic sulfonate derivatives of chiral epoxy alcohols.

标 题:Aliphatic polyimides from unsaturated monoanhydride or unsaturated diacid reacted with both monoamine and diamine
发明人:DUAN YANNAN; AVAKIAN ROGER W
权利人:POLYONE CORP
摘要:Aliphatic polyimides are synthesized by a reaction of 2 moles of an unsaturated monoanhydride or an unsaturated diacid with both one mole of a diamine and one mole of a monoamine. Imidization of intermediates so formed from those reactions resolve to 6 possible bicyclic imidic structures bridged by monoamidic or saturated hydrocarbon spans, more likely the latter. Bio-derived monomers are particularly useful in the synthesis of the aliphatic polyimides.
