标题:Homogeneous synthesis of cellulose ethers in ionic liquids

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:Process for the manufacture of alkylene carbonates
发明人：VENTURELLO CARLO; D ALOISIO RINO
权利人:MONTEDISON SPA
摘要:A new process is disclosed for the synthesis of alkylene carbonates having from 2 to 4 carbon atoms in the chain, starting from a corresponding halohydrin having the formula: wherein Ra, Rb, Rc and Rd are independently hydrogen or alkyl, aryl, alkylaryl or arylalkyl radicals and where X is a halogen, characterized in that said halohydrin is reacted with a bicarbonate of a quaternary -onium compound, where '-onium' means ammonium, phosphonium, arsonium or stibonium, preferably using an organic solvent as diluent and operating in the presence of carbon dioxide.

摘要:This invention is a method for forming hypohalous acid in a mass transfer device. The method comprises: (1) feeding into the device a stream of caustic solution comprising at least one alkali or alkaline earth metal of a hydroxide, oxide, hypohalite, bicarbonate, or carbonate; (2) feeding a stream comprising halogen gas into the device; (3) reacting at least some of the halogen gas with the caustic solution to form a solution containing hypohalous acid; (4) desorbing the hypohalous acid from the solution and into the stream of halogen gas; and (5) removing the stream of halogen gas from the device. In this method, the mass transfer device comprises a porous rotor which is permeable to the streams, and is rotated about an axis such that the streams flow through the rotor and the stream of caustic solution flows radially outward from the axis.

摘要:The invention relates to a process for the oxidation of mesitol with singlet oxygen, which is released from hydrogen peroxide, this release taking place in the presence of a bismuth compound as catalyst. In the process, 2,4,6-trimethylquinol is formed in high yield and selectivity as product, which can be used in further reactions for the synthesis of vitamins and in particular of vitamin A and vitamin E.

标题:Process of purifying phosphoramidites
发明人：ROSS BRUCE; SONG QUANLAI
权利人:ISIS PHARMACEUTICALS INC
摘要:A process of purifying phosphoramidite precursors useful in inter alia synthesis of oligonucleotides comprises dissolving a crude phosphoramidite in a polar phase, adding a basic compound to the polar phase, adding a portion of water to the polar phase, contacting the polar phase with a first apolar phase to extract impurity into the apolar phase, separating the first apolar phase from the polar phase, adding a second aliquot of water to the polar phase, and contacting the polar phase with a second apolar phase, whereby the phosphoramidite partitions into the second apolar phase.

摘要:A method of preparing tetrabromobenzoate compounds from tetrabromophthalic anhydride by reacting tetrabromophthalic anhydride with alcohol in the presence of a decarboxylation catalyst. The reaction may be carried out in an excess of alcohol, or with a near stoichiometric amount of alcohol by performing the reaction in an inert solvent.
