    Abstract: Reactor (1) para ensayar sistemas catalíticos con tubos de contacto (2), dispuestos paralelamente entre sí en un recinto para la reacción, que están soldados en sus extremos con platos para tubos, así como con caperuzas (3) en ambos extremos del reactor, que limitan, respectivamente, un recinto de la caperuza (4), alimentándose a los tubos de contacto (2) un medio de reacción fluido (5) a través de un recinto de la caperuza (4), que recorre los tubos de contacto (2) y que se descarga a través de otro recinto de la caperuza (4) así como con un circuito cerrado para el agente intercambiador de calor con alimentación del agente intercambiador de calor (6) en un extremo del reactor, paso a través del recinto intermedio comprendido entre los tubos de contacto (2) y descarga por el otro extremo del reactor, caracterizado porque los tubos de contacto (2) están dispuestos, agrupadamente, en dos o varias zonas de tubos de contacto (7), separadas térmicamente entre sí.

    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: A reactor for testing catalyst systems which has a plurality of catalyst tubes ( 2 ) which are arranged parallel to one another in the interior space of the reactor and whose ends are welded into tube plates and also has caps ( 3 ) at each end of the reactor which each bound a cap space ( 4 ), with a fluid reaction medium ( 5 ) being fed via one cap space ( 4 ) into the catalyst tubes ( 2 ), flowing through the catalyst tubes ( 2 ) and being discharged via the other cap space ( 4 ), and is also provided with a heat exchange medium circuit in which the heat exchange medium ( 6 ) is fed in at one end of the reactor, flows through the intermediate space between the catalyst tubes ( 2 ) and flows out at the other end of the reactor, wherein the catalyst tubes ( 2 ) are arranged in two or more catalyst tube regions ( 7 ) which are thermally separate from one another, is proposed.

    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.
