标题:Synthesis of succinimides and quaternary ammonium ions for use in making molecular sieves
发明人：SCHMITT KIRK D; ZUSHMA STEPHEN; BURTON ALLEN W
权利人:EXXONMOBIL CHEMICAL PATENTS INC
摘要:The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.

标 题:Process for the preparation of polyamines from N-monoaryl-N',N'-dialkyl urea compounds and their use for the synthesis of polyurethanes
发明人：RASSHOFER WERNER; GROEGLER GERHARD
权利人:BAYER AG
摘要:This invention relates to an improved process for the preparation of aromatic polyamines containing urethane and/or biuret and/or urea and/or isocyanurate groups and preferably also ether groups by the hydrolysis of poly-N-monoaryl-N',N'-dialkyl urea compounds (1-aryl-3,3-dialkyl ureas). The ureas are obtained by the reaction of secondary aliphatic, cycloaliphatic or saturated heterocyclic amines with divalent to tetravalent isocyanate compounds containing isocyanate end groups attached to aromatic residues. The ureas correspond to the general formula: wherein R1, R2 denote alkyl or cycloalkyl groups, or together form a ring and A denotes a divalent to tetravalent residue attached to the ureas by aromatic groups. Hydrolysis is carried out in the presence of water and up to two equivalents of a base containing hydroxide ions and/or up to two equivalents of a compound containing tertiary amino groups, optionally in the presence of solvents. The use of the polyamines obtained by this process for the synthesis of polyurethanes is also described.

发明人：TALMA AUKE G; HOOFT HENDRIKA P M; VAN DE BOVENKAMP-BOUWMAN ANNA
权利人:AKZO AMERICA INC
摘要:The present invention relates to an improved synthesis method for the making of citraconimides wherein a citraconic anhydride is reacted with 0.5 to 2.0 equivalents of at least one amine salt. This process may be carried out in a solvent and generally leads to excellent yields of the citraconimides with high selectivity and easy purification. The present inventional so relates to a process for the production of citraconic anhydride from itaconic anhydride with an amine or phosphine catalyst and in a cosolvent.

摘要:Various embodiments provide random copolyimides that may possess the mechanical, thermal, chemical and optical properties associated with polyimides yet achieve a low energy surface. In various embodiments, the copolyimides may be prepared using a minor amounts of a diamino terminated fluorinated alkyl ether oligomer and a diamino terminated siloxane oligomer. The various embodiments include processes for making the copolyimides containing fluorine and silicon surface modifying agents and anisotropic coatings and articles of manufacture from them. Thus the coatings and articles of manufacture made with the copolyimides of the various embodiments may be characterized as having an anisotropic fluorine and silicon composition and low surface energy.

标题:Synthesis of polyurethane products
发明人：HOSTETTLER FRITZ
权利人:PIRRI JAQUELYN P; HOSTETTLER FRITZ
摘要:Wide range of polyurethane products, e.g., cellular, dense elastomer, and integral skin microcellular products, obtained by the reaction of (a) a polyisocyanate compound, (b) a polyol, (c) optionally a chain extender and/or blowing agent with/without other known additives, (d) in the presence of a nonhydroxyl flow modifier characterized by carbon and hydrogen atoms, at least one and, generally, a plurality of oxyalkylene groups, and at least one urethane, $(1,5)omicronp. Several of the polyurethane products exhibit unique properties, e.g., foamed articles with capability to conduct static electricity, soft elastomers characterized by improved coefficient of friction, etc. Several classes of the flow modifiers are novel per se. The polyurethane products can be synthesized via the one shot or prepolymer process. Multipackage systems, in particular, two and three component systems are useful in molding operations, e.g., manufacture of shoe soles.
