Process for controlled degradation of liquid glucose syrups and cement additive products therefrom |
摘要 |
A process for the controlled degradation of liquid glucose syrups in concentrated solution and in homogeneous phase wherein the reducing groups of glucose, maltose and maltodextrin are converted into the salts of the corresponding aldonic acids and/or into the salts of lower carboxylic acids (C1-C4) without substantially changing the polysaccharide components (degree of polymerization>3) of maltodextrin, or with only partial depolymerization of the polysaccharide components, by using simple oxidants such as hypohalogenites or ferricyanides, or aqueous alkaline solutions. The conversion of the reducing sugars is equal to or greater than 95%, and a very high reproductibility of the desired results is obtained. The invention also concerns the product obtained by the process and its use as an additive to cement mortars and concretes.
