摘要： The present invention concerns a composition comprising Mn(II) acetate, a protonated salt of a cyclic triamine, a polysaccharide absorbent, and a water-soluble polymer, e.g. polyvinylalcohol. The invention also concerns a method of making such compositions, preferably in the form of a granule, and bleaching formulations comprising the salt and a peroxy compound or precursor thereof. The protonated ligand salt and Mn(II) acetate containing composition and formulations comprising it, are suitable for use in catalysing oxidation, for example as a component of a laundry or dishwasher bleaching composition. The invention further relates to cleaning agents comprising the compositions described herein.

摘要： Disclosed is a process for the preparation of polyesters, comprising the following steps and characterized by the following measures:
a) suspending polyethylene terephthalate waste in ethylene glycol and/or in 1,2-propylene glycol containing a transesterification catalyst,
b) heating the reaction mixture to depolymerize the polyethylene terephthalate waste for a time sufficient to decompose the polyethylene terephthalate into monomers and into oligomers,
c) addition of end group forming monomers in the form of polyalkylene glycol monoalkyl ethers, fatty alcohols, fatty amines, fatty acids or esters thereof or mixtures of two or more thereof, and/or sulfo(poly)alkylene glycols and/or sulfoaryl carboxylic acids or esters thereof,
d) addition of sulfoarylene dicarboxylic acids or polyester-forming derivatives thereof,
e) optionally adding aliphatic diols, cycloaliphatic diols, organic dicarboxylic acids, their polyester-forming derivatives, crosslinkers or mixtures of two or more thereof,
f) heating the reaction mixture while distilling off ethylene glycol, optionally 1,2-propylene glycol and further compounds present in the reaction mixture or formed by transesterification and polycondensation, with the proviso that the temperature of the reaction mixture does not exceed 250° C.
This process enables the production of polyethylene or polypropylene terephthalates with selected end groups from polyester waste. The process products are characterized by good soil release properties and can be used as additives in detergents and cleaning agents.-

摘要： The present invention concerns a granule comprising Mn(II) oxalate, a protonated salt of a cyclic triamine, a polysaccharide absorbent and a coating agent. In another embodiment the invention concerns a granule comprising a polysaccharide absorbent, a protonated salt of a cyclic triamine and no or very small amounts of Mn. The invention also concerns methods of preparing said granules comprising Mn(II) oxalate, polysaccharide absorbent and such salts or comprising polysaccharide absorbent, such salts and no Mn compound and bleaching formulations comprising the granules and a peroxy compound or a precursor thereof. Granules comprising Mn(II) oxalate, polysaccharide absorbent and the salt or comprising polysaccharide absorbent, the salt and no Mn compound, and formulations comprising these are suitable for use in catalysing oxidation, for example as a component of a dishwasher bleaching composition. The invention further relates to methods of oxidising with the bleaching formulations described herein.

摘要： Described are co-granules coated with cellulose ether and containing b1) cyclic sulfonimine, b2) bleach activator selected from the group consisting of tetraacetylethylenediamine, decanoyloxybenzoic acid or mixtures thereof, and b3) cellulose ether as binder. These co-granules can be produced by wet granulation and are very storage-stable.
The co-granules can be used in detergents and cleaning agents, which contain (a) bleaching agent selected from the group consisting of perborate, percarbonate or mixtures thereof, and (b) the co-granules coated with cellulose ether. These detergents and cleaning agents contain highly active bleach activators and bleach catalysts and are characterized by high storage stability. The combination of components b1) and b2) and peroxygen compound a) leads to a pronounced disinfection effect even at low temperatures.
The detergents and cleaning agents can be used even at low temperatures and show a good washing performance.
