Subsititue Material As Well As Production Process And Application
-
Paragraph 0095; 0096, (2017/08/28)
The invention relates to a production process of a functionalized material containing acid groups and an application thereof. The material is used as a nonhomogenous catalyst, and can be used for removing organic and inorganic compounds in product streams, process streams and waste liquid, or can be used as a cation and anion exchanger, a metal chromatography material, a solid phase purifying or extracting material, a fixed biological moleculaar material, a solid phase sythesizing material and a chromatography material. The invention also relates to a novel sulfonic acid or hypophosphorous organic funtionalized silica gel and metal salts thereof.
FUNCTIONALISED MATERIALS, PROCESS FOR THE PRODUCTION AND USES THEREOF
-
Paragraph 0041; 0052, (2015/04/22)
The invention relates both to processes for the production of functionalised materials containing alkyl sulfonic acids groups and their use as heterogeneous catalysts. The invention also relates to precursors of these new products and new organopolysiloxane sulfonic acids.
Chemistry in Water - Part VI. Catalytic Isomerization and Stereochemistry of Reduction of Acetylenics Mediated by Water-Soluble Phosphines

, p. 4331 - 4334 (2007/10/02)
Reaction of water-soluble phosphines with disubstituted electrodeficient alkynes in H2O (D2O) gives rise either to mixtures of cis and trans (dideuterated) olefins or specifically to trans (dideuterated) olefins, by simple control of the phosphine amount.A cis-trans olefin isomerization catalyzed by sulfonated phosphines occurs in water and allows the obtention of specifically trans disubstituted alkenes from the corresponding cis isomers.
