Abstract: On-spec phthalic anhydride is prepared by distillative purification of crude phthalic anhydride by a process in which crude phthalic anhydride is fed to a distillation column which is operated at reduced pressure, the low boilers are removed at the top or in the vicinity of the top of the distillation column and the on-spec phthalic anhydride is removed from the column via a side take-off.

Abstract: The invention relates to a method for the production of phthalic anhydride to a specification, using a distillative purification of crude phthalic anhydride, by introduction of crude phthalic anhydride into a distillation column, operating at reduced pressure, withdrawal of the low-boiling fraction from the head, or near the head of the column and withdrawal of the phthalic anhydride, which meets the specification, from a side-tap on the column, whilst operating the column at a reflux ratio x, with 1:1.7

Abstract: Microencapsulation of dispersed core material involves polycondensation of a melamine-formaldehyde (MF) resin mixture comprising: (a) an aqueous solution of a condensate of: (a1) 1 mole melamine; (a2) 2-5 mole formaldehyde; (a3) 0-0.5 mole melamine derivative; and (a4) 1-5 mole 1-3 carbon (C) alkanol; and (b) 0.01-1 mole water-soluble primary, secondary or tertiary amine or ammonia. In the production of microcapsules by polycondensation of a melamine-formaldehyde resin mixture in water, in which the capsule core material is dispersed, in the presence of an anionic protective colloid, the resin mixture comprises: (a) an aqueous solution of a condensate of: (a1) 1 mole melamine; (a2) 2-5 mole formaldehyde (HCHO); (a3) 0-0.5 mole melamine derivative capable of addition or condensation reaction with HCHO; and (a4) 1-5 mole 1-3 carbon (C) alkanol; and (b) 0.01-1 mole water-soluble primary, secondary or tertiary amine or ammonia. Independent claims are also included for: (a) microcapsules produced by this method; and (b) a melamine-HCHO resin mixture of the above composition.

Abstract: Aqueous resin compositions (I) with a viscosity of 100-3000 mPa.s at 20 deg C, containing 65-80 wt% of a resin obtained from melamine (M), formaldehyde (F) and optional additive(s). Independent claims are also included for (a) a process for the production of (I) by mixing the above starting materials in an aqueous condensation phase, heating until the phase is transparent and then removing water until the product has the required resin content and viscosity; (b) composites containing (I) after thermal treatment, plus a carrier material; (c) a process for the production of these composites by bringing (I) and the carrier material into contact with one another at 60-300 deg C; (d) composites obtained by process (c); (e) a process for the production of a stable impregnating resin dispersion by dispersing (I) with small particles.
