The invention relates to an aqueous polyester concentrate having a proportion by weight of polyesters of 12 to 60%, wherein the polyesters are obtainable by means of polymerization of the components selected from a) one or more sulfo group-free aromatic dicarboxylic acids and/or salts thereof and/or anhydrides thereof and/or esters thereof, b) optionally one or more sulfo group-containing dicarboxylic acids, salts thereof and/or anhydrides thereof and/or esters thereof, c) 1,2-propylene glycol, d) ethylene glycol, e) one or more compounds of the formula (1) RO(CHRCHRO)H (), where Ris a linear or branched, saturated or unsaturated alkyl group having from 1 to 22 C atoms, Rand R, independently of one another, are hydrogen or an alkyl group having from 1 to 4 carbon atoms, and n is an integer of from 1 to 50, f) optionally one or more compounds of the formula (2) H&#x2014;(OCHCH)&#x2014;SOX (2), where m is an integer of from 1 to 10 and X is hydrogen or an alkali metal ion, and g) optionally one or more cross-linking polyfunctional compounds, provided that at least one of the components b) or f) is present, and provided further that the molar ratio of the components c) 1,2-propylene glycol to d) ethylene glycol is greater than or equal to 1.60.

Polyester concentrates having high stability in solution and having a greying-inhibiting effect

The invention relates to a method for isolating concentrated paraffin sulfonic acids from reaction mixtures that are produced during the sulfoxidation of n-paraffins, from which a major part of the sulfuric acid and the paraffin was removed by phase separation and which contain, in addition to the free paraffin sulfonic acids, n-paraffins, water and optionally minor amounts of sulfuric acids. The method according to the invention is characterized by removing paraffin and optionally residual water by vacuum distillation. The paraffin sulfonic acids obtained by distillation have a content of more than 85% by weight of the active substance. The material is pale, odorless and low in sulfuric acid and paraffin.

The invention relates to a one-pot reaction for the production of 3,7-diaza-bicyclo[3.3.1]nonane compounds, wherein in a first step a dicarboxylic acid ester is reacted with a pyridine aldehyde and a primary amine. The piperidone created in this manner is reacted with formaldehyde and a further primary amine in a second step. It is essential to the invention that both reaction steps are carried out in a one-pot variation in a C-Calcohol as the solvent, and that the reaction water created is removed by means of distillation.

A process for preparing acyloxybenzenesulfonates by reacting anhydrous phenolsulfonates with carboxylic acid derivatives comprises conducting the reaction with a salt of a phenolsulfonic acid which has a water content of less than 0.5% by weight and has been contacted with a substance having basic properties.

Process for preparing acyloxybenzenesulfonates

The invention relates to a process for the preparation of acyloxybenzenesulfonates starting from carbonyl halides and salts of phenolsulfonic acid which have a low water content. Surprisingly, it was discovered that acyloxybenzenesulfonates can be prepared in high yields and good grades, irrespective of the grade or reactivity of the phenolsulfonic acid derivative, if the reaction of the phenolsulfonic acid with an alkanecarboxylic acid derivative is carried out in an aliphatic or aromatic solvent in the presence of 0.5 to 25% by weight of a polyglycol ether.

Process for the preparation of acyloxybenzenesulfonates

Process for the preparation of acyloxybenzenesulfonates by reaction of phenolsulfonate with a water content of less than 0.5% by weight and alkanecarbonyl halide in a hydrocarbon as solvent and in the presence of a catalyst in the form of a basic nitrogen-containing compound.
