Poly-di:carboxy-saccharide] prepn. for detergent compsn. builder - by oxidn. of polysaccharide(s) in presence of hypohalite as oxidising agent with low oxidising agent concn. during reaction |
摘要 |
<p>Method for the prepn. of polydicarboxysaccharides by oxidn. of polysaccharides in the presencee of a hypohalite as oxidising agent in a reaction medium comprises oxidising in the presence of hypobromite and/or hypoiodite with a low oxidising agent concn. during the reaction. Also claimed are calcium binding agents used in detergents comprising the polydicarboxysaccharide and the detergents contg. the calcium binding agents.</p> |
