Abstract: Reactor (1) comprises several contact tubes (2) in parallel in the reactor inner chamber and welded to the reactor base. Caps are on both reactor ends to form a cap chamber. A fluid reaction medium is introduced into the tubes via one cap chamber, flows through the contact tubes and flows out through the other cap chamber. The contact tubes are in two or more contact tube regions (7) thermally separated from each other. An Independent claim is also included for a process for testing catalyst systems. Preferred Features: At least one contact tube with a sleeve (9) for receiving a thermocouple and filled with Al2O3 is in one or more contact regions and closed at both ends. A cover is provided for the contact tubes of one or more contact regions.

Abstract: The invention relates to a pump (1) comprising a pump feed tube (13) for transporting a heat exchange medium (6) for a reactor containing a bundle of catalyst tubes (2). The pump (1) has a housing (14) that surrounds the pump feed tube (13) and comprises an opening (15) in the lower part of the housin g (14), which allows the heat exchange medium (6) that is drawn from the lower section of the reactor by the pump (1) to flow into the housing (14). The medium flows upwards in the section lying between the internal wall of the housing (14) and the external wall of the pump feed tube (13), optionally ov er a heat exchanger (18) and into the interior of the pump feed tube (13) via a n opening (16) in the upper section of said pump feed tube (13). The medium th en flows through the pump feed tube from top to bottom, into the reactor via an opening (17) in the lower section of said tube (13) and into the upper secti on of the intermediate chamber between the catalyst tubes (2).

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.
