Polymers of a poly(meth)acrylic acid main chain in which, based on the main chain, 0 to 30% by weight of the (meth)acrylic acid basic building blocks may be replaced by maleic acid (anhydride) basic building blocks, fumaric acid basic building blocks or mixtures thereof and 0 to 10% by weight of the (meth)acrylic acid basic building blocks may be replaced by other copolymerizable ethylenic basic building blocks,and C1-30-alkylpoly-C2-4-alkylene glycols, bonded to the main chain via ester groups, having an average molecular weight of from 250 to 10 000 as side chains,where, based on the polymer, 1 to 19% by weight of the main chain and 81 to 99% by weight of the side chains are present and this ratio and the average molecular weight of the side chains are chosen such that free carboxyl groups are present in the polymer,are used as controllable dispersants for detergents or cleaners or constituents thereof.
摘要:
A process for producing agglomerates with a core/shell structure, in which i) initial agglomerates containing a first particulate solid are prepared; ii) a second particulate solid is agglomerated in the presence of the initial agglomerates with the addition of a binder liquid to give second stage agglomerates and, where appropriate, iii) an nth (n≧3) solid is agglomerated in the presence of the (n−1)th stage agglomerates with the addition of a binder liquid to give nth stage agglomerates.

Octadienols are prepared by reacting 1,3-butadiene with water in the presence of a catalyst system comprising a palladium compound, a triorganophosphorus compound and carbon dioxide and in the additional presence of a triorganophosphine oxide.
摘要:
Alkyl pentenoates are prepared by reacting butadiene with carbon monoxide and an alkanol in the presence of a cobalt carbonyl complex and a tertiary, aromatic heterocyclic nitrogen base at from 80.degree. to 160.degree. C. under from 100 to 1,000 bar in the presence of from 0.1 to 10% by volume of hydrogen, based on the amount of carbon monoxide used.
摘要:
Carbalkoxy-containing aliphatic compounds are prepared continuously by reacting an olefinically unsaturated aliphatic compound with carbon monoxide and an alkanol in the presence of a cobalt carbonyl catalyst and a tertiary nitrogen base at from 80.degree. to 200.degree. C. and under from 100 to 1,200 bar by an improved process in which carbon monoxide is circulated, and a carbon dioxide content of from 0.1 to 2% by volume is maintained in the carbon monoxide fed to the reaction.
摘要:
Process for the preparation of cyclopentane derivatives of the formula I in which R is a C1- to C10-alkyl group, which comprises reacting cyclohexanol or cyclohexene or mixtures of both compounds to give 1-methyl-1-cyclopentene (1st stage) and subsequently adding a C1- to C10-alkanol onto the double bond of the 1-methyl-1-cyclopentene (2nd stage).

摘要:
A description is given of a microcapsule formulation comprising microcapsules having a core of a hydrophobic material and a capsule shell of an addition polymer containing in copolymerized form at least 1% by weight of cationogenic monomers and/or polyethylenically unsaturated monomers whose unsaturated sites are connected via successive chemical bonds of which at least one bond is acid-hydrolyzable. A description is further given of a microcapsule formulation comprising microcapsules having a core of a hydrophobic material, which comprises at least one fragrance or perfume, and a shell of an addition polymer containing in copolymerized form at least 1% by weight of anionogenic monoethylenically unsaturated monomers and/or polyethylenically unsaturated monomers whose unsaturated sites are connected via successive chemical bonds of which at least one bond is base-hydrolyzable. The microcapsule formulations are employed in laundry detergents or cleaning products.
