标题 :Synthesis of sequestration resins for water treatment in light water reactors
发明人：YENGOYAN LEON; FRATTINI PAUL L; WELLS DANIEL MORGAN
权利人:YENGOYAN LEON; FRATTINI PAUL L; WELLS DANIEL MORGAN; ELECTRIC POWER RES INST
摘要:An organic synthesis of materials to achieve removal of low molecular weight ionic species, such as transition metal ions including cobalt, iron, nickel, and zinc, from aqueous solutions. The synthesis includes the steps of providing a cation exchange resin, functionalizing the cation exchange resin using a chloride intermediate to form a sulfonyl chloride resin, and reacting a multi-amine based ligand with the sulfonyl chloride resin to form a sequestration resin. The synthesis further includes the steps of cooling the sequestration resin, and washing and drying the sequestration resin.

摘要:The invention is directed to a simple and new method for the homogeneous synthesis of cellulose ethers. Ionic liquids are not only used as solvent, but also as reaction media for the homogeneous etherification of cellulose. The dissolved cellulose is treated with the etherification agent in the absence of organic and/or inorganic bases and in the absence and/or in the presence of moderate amounts of water. The obtained cellulose ethers show new distributions of substitution on the polymer chain, resulting in new properties and applications.

标 题:Catalyst for synthesis of vesicular phenoxy resins
发明人：BENNETT EVERETT W
权利人:JAMES RIVER PAPER CO
摘要:A catalyst for synthesis of vesicular phenoxy resins is disclosed. The catalyst includes a water-insoluble complex of a hydric phenol and a quaternary ammonium or phosphonium salt of the hydric phenol. Preferably, the hydric phenol is an intermediate of the phenoxy resin being produced. Dihydric phenols, such as sulfonyldiphenol are preferred. The invention further relates to a reaction medium for polymerization of phenoxy resins including the above-described catalyst and a solvent medium capable of dissolving the phenoxy resins and otherwise not interfering with the polymerization reaction. The solvent medium is advantageously free of toxic Methyl Cellosolve.

权利人:BIOVECTOR THERAPEUTICS SA
摘要:A biodegradable particulate vector is disclosed and is characterized in that it comprises: a nucleus consisting of a cross-linked polysaccharide or oligosaccharide matrix to which ionic ligands are attached; a first semi-permeable lipid layer linked to the nucleus by covalent bonds; a second layer of amphiphilic compounds linked to the first lipid layer by hydrophobic interactions. A method for synthesis of said vector is also disclosed.

摘要:A method for hydrophilization and/or surface area enlargement of a porous base matrix comprising on its inner and/or outer surfaces a polymer (P′) carrying nucleophilic groups X′. The method is characterized inn (a) ethoxylating a plurality of said X′ thereby transforming them to groups comprising —(CH 2 CH 2 O) n H, or (b) (i) ethoxylating a polymer (P″) carrying nucleophilic groups X″ thereby transforming P″ to a polyhydroxy polymer (P′″) carrying a plurality of —(CH 2 CH 2 O) n H groups, whereafter (ii) P′″ is attached to the base matrix. n is an integer ≧1. nn A support matrix which is obtainable by the method. The support matrix has a sufficient rigidity and swellability to permit liquid flow of a velocity >5 cm/h through the matrix when in form of particles packed to a bed or in form of a porous monolithic plug. n The use of the support matrix defined in liquid chromatography, cell culturing, stepwise solid phase synthesis of organic molecules, affinity adsorption in suspensions, solid phase catalysis with an immobilized catalyst.
