Abstract: Prepn. of esters of at least 36C aromatic di-, tri-, and/or tetra-carboxylic acids with mol. wt. 550-1500 by reaction of the acids, or their anhydrides, with at least 12C aliphatic alcohols, at 130-250 deg.C, in absence of a solvent, is in presence of (a) a sulphonic acid or (b) an amine, with passage of an inert gas. Pref. reaction is in presence of (a) 0.001-2 (0.001-0.2) mols % of sulphonic acid, or (b) 0.001-5 (0.001-0.2) mols % of amine, w.r.t. acid or anhydride. USE/ADVANTAGE - The higher esters are used as fuel additives. Reaction time is shorter, and problems of sepn. and purification are avoided.

Abstract: The invention relates to a process for the preparation of water-dilutable, low-formaldehyde urea-formaldehyde condensates which have a low viscosity and a long shelf life by condensing urea and formaldehyde in a molar ratio of from 1:2.0 to 2.25 in the presence of alkali metal sulphite at a pH of from 9.0 to 10.5 and a temperature of from 80 DEG C to the reflux temperature, and subsequently continuing the condensation at a pH of from 4.0 to 6.0 and at from 70 to 95 DEG C, where from 0.01 to 0.03 mol of alkali metal sulphite are employed per mol of formaldehyde, the condensation at pH 4.0 to 6.0 is carried out with addition of from 0 to 0.2 mol of a water-soluble alkanol per mol of formaldehyde until infinite water-dilutability is just achieved, urea is subsequently added until the overall urea:formaldehyde molar ratio is from 1:1.60 to 1.95, and then from 0.01 to 0.04 mol of glyoxal are added per mol of formaldehyde, and to the use of the urea-formaldehyde condensates as binders for fibre nonwovens made from organic and/or mineral fibres.

Abstract: A process for the preparation of reinforced rubber vulcanisates by vulcanisation of mixtures of natural rubber or synthetic rubbers with novolak resins in the presence of a curing agent, in particular hexamethylenetetramine, where the temperature at which the resins are mixed in is kept at or up to 50 DEG C below the softening points of the resins.
