摘要： A superabsorbent material with enhanced odour control and control of bacterial growth comprises a non-acidic, alkali-neutralising compound selected from acid anhydrides, lactides, lactones and hydrolysable esters, especially cyclic acid anhydrides, lactides and lactones of η- or δ-carboxylic acids. The superabsorbent material can be used in hygiene products such as diapers.

摘要： A process for oxidising cellulose, in which a nitroxyl compound such as TEMPO is oxidised using an oxidising agent in the presence of a complex of a transition metal such as Mn, Fe, Cu, and a complexing agent such as a polyamine, or an oxidative enzyme, and the resulting nitrosonium ion is used to selectively oxidise the cellulose 6-hydroxy-methylene groups to carbaldehyde groups and carboxylic acid groups.

摘要： The invention pertains to a process for producing oxidised cellulose having a high molecular weight, by pre-treating cellulose in a non-alkaline solvent for cellulose so as to lower its crystallinity, and then oxidising it using an oxidising system predominantly oxidising the 6-hydroxymethyl groups or the 2,3-dihydroxyethylene groups to carbaldehyde and/or carboxyl groups. The oxidising agent is preferably a nitroxyl compound or periodate, and the product is useful as a water absorbent.

摘要： A superabsorbent article of the invention having improved odour control and microbial control, comprises a liquid-impervious back layer, a liquid-absorbing intermediate layer containing a partially neutralised, acidic hydrophilic polymer, especially a surface-crosslinked polyacrylate, and a liquid-pervious, non-absorbing top layer, and is characterised by comprising an alkali-neutralising agent which is evenly distributed in said absorbing intermediate layer.

摘要： Carbohydrates having primary hydroxyl groups, such as starch and cellulose, can be selectively oxidised to carboxylic carbohydrates by oxidation with molecular oxygen, using a nitrogen oxide such as a nitrite salt, as a catalyst. The reaction is advantageously carried out in a dehydrating solvent such as concentrated phosphoric acid.

摘要： The invention pertains to a process for the regeneration and recovery of periodate from a spent iodate solution, by reacting the iodate with at least an equimolar amount of hypohalite, and carrying out the recovery in the presence of a water-miscible organic solvent or potassium ions or divalent metal (especially calcium) ions. The regenerated periodate is especially suitable for oxidising carbohydrates to dialdehyde carbohydrates.
