摘要： The invention relates to functionalised inorganic oxide products and their use in the removal of heavy metals, transition metals and activide metals from solution. The product is obtained by reacting an inorganic solid containing surface hydroxyl groups such as silica with a compound of formula:
wherein R is a divalent organic group containing up to 20 carbon atoms; R 1 , R 2 and R 3 are independently-OR 8 groups wherein R 8 represents a hydrogen atom or an alkyl, aryl or acyl group containing up to 20 carbon atoms; R 4 , R S , R S and R 7 represent independently hydrogen atoms, alkyl or aryl groups containing up to 20 carbon atoms and n and m are integers in the range 1 to 5. The product is particularly suitable for removing rhodium from solutions obtained from rhodium catalysed reactions in which a carboxylic acid, an anhydride, an ester, an alcohol or an ether is produced.

摘要： A functionalised solid product containing sulphonate or sulphonic acid groups is prepared from an inorganic oxide containing surface hydroxyl groups, e.g. silica by reacting the latter in a first stage with a haloalkyl alkoxy- or arylox- ysilane. The first stage product is then reacted with an aqueous solution of an inorganic sulphite to give a product containing sulphonate groups. These can be converted to sulphonic acid groups by an optional third stage treatment with dilute mineral acid. The final products are suitable for use as adsorbent materials or catalyst supports.
