标 题:Synthesis of a dendritic polyalcohol

摘要:A process for a double stage convergent synthesis of a polymeric polyalcohol substantially and preferably built up from polyester units and composed of a monomeric or polymeric core to which at least one hyperbranched dendritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymeric or monomeric branching chain extender having three reactive functions of which two are hydroxyl groups and one is a carboxyl group. The two hydroxyl groups of the branching chain extender is in a first step ketal protected by reacting said two hydroxyl groups with a ketal. A second step includes protection of the carboxyl group of said branching chain extender. The ketal protected branching chain extender and the carboxyl protected chain extender are then employed for repeated addition in a number of step yielding a predetermined number of branching generations. The thus synthesized dendron is finally added to a core having reactive hydroxyl or epoxide groups and the ketal protected hydroxyl groups are optionally deprotected.

摘要:The present invention concerns a peptide of the general formula (I): n R 1 -(AA) n -X 1 —X 2 —X 3 -Pro-X 4 —X 5 —X 7 -(AA) p -R 2 , capable of activating the synthesis of proteins of the family of aquaporins. n The present invention also concerns a cosmetic, nutraceutical or pharmaceutical composition, comprising a peptide of general formula (I) as active principle. The invention also relates to the use of this new active principle in a cosmetic or nutraceutical composition, intended to improve the moisturizing and the barrier function of the epidermis and intended to stimulate cutaneous regeneration. The invention also relates to the use of this new active principle to realize a pharmaceutical composition, and in particular a dermatological composition, intended to regulate and/or stimulate the activity of the aquaporins and to thus treat the pathological dryness of the skin or mucosa. The invention also relates to a method of cosmetic treatment intended to prevent or combat against dryness of the skin and mucosa, and the manifestations of cutaneous ageing.

摘要:The embodiments herein provide a method of synthesis for metallic nano-products such as metallic nano-antennas, metallic nano-rods, metallic nano-wires, metallic nano-prolate spheroids and metallic nano-oblate spheroids using saturated and unsaturated carboxylic acids. The method involves preparing a reaction mixture by mixing a polar protic solvent, a polar aprotic solvent or a non-polar solvent, a saturated fatty acid or an unsaturated fatty acid and a metallic salt. Then a mixture of reducing agents is prepared by mixing a polar protic solvent, a polar aprotic solvent or a non-polar solvent and a saturated fatty acid or an unsaturated fatty acid. The reaction mixture and the mixture of reducing agents are combined and heated solvo-thermally for a pre-determined period of time at a pre-determined temperature.

标题 :Glycolysis of cured unsaturated polyesters for producing a recycle reactant
发明人:TUFTS TIMOTHY A; TSAI CHUNG-CHIEH; HUPP STEPHEN S
权利人:ASHLAND OIL INC
摘要:The present invention is directed to a method for treating cross-linked (cured) filled or untilled unsaturated polyester for deriving an alcohol recycle reactant useful in the synthesis of alcohol-formed derivative products. The first step of the method is the attrition of the cured unsaturated polyester to form particulates thereof. In the next step of the process, at least a fraction of any filler or fiberglass in the cured unsaturated polyester is separated to form a cured unsaturated polyester regrind. The next step is the subjecting of the cured unsaturated polyester regrind to agitated, uncatalyzed or catalyzed glycolysis in the presence of excess glycol and, optionally, a transesterification catalyst under agitation at elevated transesterification temperature. The final step of the process is the recovery of the recycle alcohol reactant for use in the synthesis of alcohol-formed derivative products. The glycolysis reaction is conducted under agitation in order to keep the cured unsaturated polyester regrind solids suspended during the glycolysis reaction. In this regard, establishment of shear conditions should aid in the glycolysis step of the process.

摘要:Betain group-containing derivatives of carboxymethylcellulose are disclosed. They are characterized in that all or a portion of the carboxymethyl groups are or is replaced by groups of the general formula wherein R1 is hydrogen or methyl group, R2 is a divalent aliphatic hydrocarbon group with 2 to 5 carbon atoms, R3, R4 is an alkyl group with 1 to 4 carbon atoms, R5 is a divalent aliphatic hydrocarbon group with 1 to 10 carbon atoms, with the proviso that, on the average, at least 0.1 betaine groups are contained for each anhydroglucose unit of the polymeric molecule. Also, a method for the synthesis of these compounds and their use in cosmetic preparations, especially for the care of hair, are disclosed. In addition, novel derivatives of carboxymethylcellulose with tertiary amino groups are taught as intermediates. In these derivatives, all or a portion of these groups are or is replaced by groups of the general formula in which the substituents R1, R2, R3 and R4 have the above meaning, with the proviso that, on the average, at least 0.1 tertiary amino groups are contained per anhydroglucose unit of the polymeric molecule.
