Abstract: The invention relates to the use of copolymers consisting of (a) between 10 and 95 weight % of at least one non-ionic monomer which has a N-vinyl group and at 25 DEG C has a water solubility of at least 60 g/l, (b) between 5 and 90 weight % of at least one hydrophobic monoethylenically unsaturated monomer which at 25 DEG C has a water solubility of less than 60 g/l, and possibly (c) between 0 and 15 weight % of at least one monoethylenically unsaturated monomer having an ionic or ionisable group and (d) between 0 and 10 weight % of at least one monomer which has at least 2 ethylenically unsaturated groups. Said copolymers are used in detergents, in amounts of between 0.1 and 5 weight % in relation to said detergents, as additive which inhibits greying and promotes dirt removal during washing and as a secondary treatment agent for laundry.

Fikentscher method on the sodium salt in a 1 wt. % aqueous solution at 25 DEG C and pH 7) of at least 8.5.

Abstract: The preparation of adipic acid comprises the following steps: a) hydroformylation of pentenoic esters by reaction with carbon monoxide and hydrogen at elevated temperature and under elevated pressure in the presence of cobalt carbonyl or rhodium carbonyl complexes with the formation of a mixture comprising 5-, 4- and 3-formylvaleric esters b) separating the 5-formylvaleric esters from the mixture thus obtained of 5-, 4- and 3-formylvaleric esters, leaving a mixture substantially comprising 4- and 3-formylvaleric esters behind c) dehydrocarbonylation of the mixture substantially comprising 4- and 3-formylvaleric esters in the presence of at least one element from Subgroup VIII of the Periodic Table at a temperature of 50 to 400 DEG C with the formation of pentenoic esters, which are recycled into step a) for hydroformylation d) oxidation of the 5-formylvaleric esters from step b) with molecular oxygen or gases containing such oxygen to give monoadipates and e) hydrolysis of the monoadipate to give adipic acid.
