摘要:The present disclosed are a high exchange-capacity anion exchange resin with dual functional-groups and method of synthesis thereof. The invention relates to the field of environmental function material synthesis and application. The resin is based on chloromethylated polystyrene-divinylbenzene polymer as matrix, and by primary amination and quaternization, yields an anion exchange resin with dual functional-groups having both a weak base anionic group and a strong base anionic group. The anion exchange resin not only has high adsorption capacity for water-born nitrate ions, but also can effectively squelch natural organic acids such as phytic acid in water, thus simultaneously removing nitrate ions and phytic acid organic matter from water. Therefore, the resin has a broad application potential in the fields of drinking water treatment, groundwater remediation, and advanced urban sewage treatment.

摘要:Betaine group-containing polysaccharides with recurring anhydroglucose units of the average, general formula are disclosed. In this formula the R1 groups are the same or different and represent methyl, in which n=2 or 3, m=0 to 10, p=0 to 10 and R2 is a hydrogen atom or the betaine group in which R3 and R4 are the same or different and represent an alkyl group with 1 to 4 carbon atoms and R5 is a divalent aliphatic hydrocarbon group with 1 to 10 carbon atoms, with the proviso that at least 0.5% of the R1 groups in the polysaccharide molecule represent the betaine group. Also disclosed is a method for the synthesis of these compounds and their use in cosmetic preparations, expecially for the care of the hair. In addition, novel compounds of the general formula are disclosed as intermediates in which the substituents R3, R4 and R5 have the above meaning.

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.
