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: 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: Aromatic compounds in which at least one amino group is bonded to an aromatic nucleus are catalytically hydrogenated in the liquid phase by a process in which the catalyst consists essentially of ruthenium and, optionally at least one metal of subgroup I, VII or VIII in an amount of from 0.01 to 30% by weight, based on the total weight of the catalyst, applied to a carrier which has a mean pore diameter of at least 0.1 mu m and a surface area of not more than 15 m2/g.

Abstract: Copolymer comprising ethylene units and vinyl formate units, the content of free vinyl formate in the polymer preferably being not more than 5000 ppm, based on the weight of the copolymer, a process for its preparation, and its use as flow improver, especially in petroleum distillates, preferably fuel and propellant compositions, especially petroleum middle distillates, and also a fuel and propellant composition comprising a principal quantity of a fuel and propellant and that quantity of a copolymer as above which is effective in improving the flow properties.

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.
