摘要： A transglycosylation product, a method of producing the same and use of the product. The transglycosylation product comprises an alkyl or hydroxyalkyl glycoside of a cellulose ester or ether, wherein the alkyl or hydroxyalkyl groups of the glycoside residue comprise a carbon chain having 1 to 4 carbon atoms, and having 0 to 2 free hydroxyl groups and being attached to the 1-carbon of the anhydroglucose unit via an oxy group. The product can be produced by mixing the cellulose derivative with mono-, di- or triol to form a reaction mixture, after which the reaction mixture is heated and the reaction is continued until a clear mixture is obtained. After cooling the recoverable product is suitable for use for example as an adhesive or as a hydrophobic coating.

摘要： A method for preparing a cellulose carbamate solution. Dissolving is performed in two steps, first by moistening cellulose carbamate pulp with a dilute alkaline solution and second by admixing a concentrated alkaline solution, as cold as possible, to the pulp under intensive stirring. The technique utilizes the low freezing point of the aqueous NaOH solution at the concentration of 18%, wherein the freezing point is below −20° C., and the intensive stirring function of the dissolve mixer device during the dosage. t is possible to prepare solutions of high quality and having high dry matter content in a mixing time of a few minutes only.

摘要： A process for manufacturing transglycosylation products. According to the process, a starch derivative is reacted at acidic conditions with an alkanol containing 1-6 hydroxyl groups and the reaction product is recovered as such or it is subjected to further processing. According to the method, the transglycosylation reaction between the starch derivatives and the alkanol is carried out in a reactive extrusion process, whereby the reaction can essentially be performed in the absence of liquid media at high yield. The invention also relates to new transglycosylation products of starch derivative, containing anions derived from a phosphorus-containing acid, which are chemically bonded to the product.
