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: The novel feature in preparation of amines of formula (I) by reacting olefins of formula (II) with ammonia or H-N(R )(R ) (III) at 200-350 degrees C/100-300 bar is that the heterogeneous catalyst used is a mesoporous oxide of high surface area. R - R = 1-20C alkyl, 2-20C alkenyl or alkynyl, 3-20C cycloalkyl, 4-20C alkyl-cycloalkyl or cycloalkyl-alkyl, aryl, or 7-20C alkaryl or aralkyl; or R and R together form an optionally unsaturated 3-9C alkylene chain; and R and R = also 21-200C alkyl or alkenyl or together form 2-12C alkylene.
