Abstract: A method is provided for separating hydrogen fluoride (HF) from a mixture comprising HF complexed with an aromatic ketone in which the keto carbon atom is directly bonded to an aromatic ring carbon atom, e.g., 4-isobutylacetophenone, by adding a carboxylic acid anhydride, e.g., acetic anhydride, to the mixture while maintaining the mixture at conditions sufficient to sustain a reaction between the anhydride and the HF to form the corresponding acyl fluoride, e.g., acetyl fluoride, and carboxylic acid, e.g., acetic acid, and separating the acyl fluoride from the mixture. The method is conveniently carried out in a stripping column near the top of which the mixture comprising aromatic ketone and HF is fed and below which the anhydride is fed. Between these feed points, the uncomplexed HF is stripped from the mixture, while below the anhydride feed point or points, the anhydride reacts with the complexed HF to form the acyl fluoride which is stripped from the mixture, and the carboxylic acid. The separation method may be integrated with the production of the aromatic ketone by the Friedel-Crafts acylation of an aromatic compound, e.g., isobutylbenzene with an acyl fluoride, a carboxylic acid anhydride, a free carboxylic acid, or a mixture of the foregoing reactants, using an excess of HF as catalyst, to produce the mixture comprising aromatic ketone and HF to be separated, and to which the separated HF and in some cases the acyl fluoride may be recycled.

Abstract: The invention provides a coffin made of moulded pulp and comprising a bottom part and a top part. The halves of the coffin can also be identical and are each formed in a single operation as a moulding (40) in a positive mould (30) of a moulding press (10). They are moulded in such a way that reinforcements are provided in the corners (42) of the bottom and top parts (40) and in the region of the handles. The hydraulic moulding press (10), which can operate with a pressure of 2000 t, comprises a moveable ram (16) and a fixed die (20), which is designed as a core made permeable by openings (22). The perforated die (20) forms an inverted coffin half, the downwardly open coffin half being sealed off by a sealing plate (24). A vacuum for dewatering the pulp suspension and a positive pressure for releasing the moulding (40) from the mould can be produced in the cavity (26) of the core and thus via openings (22) in the positive mould (30, 30') via a suction- air or compressed-air line (36). The water-resistant binder contained in the pulp can be activated either during a subsequent heat treatment or during the moulding process itself, the required final strength of the coffin thereby being guaranteed. <IMAGE>

Date Jul. 23, 1992.The invention relates to an accumulator charging valve, which for the connection of an inlet P supplying a hydraulic system 10 to an outlet T when an adjustable upper charging pressure in the hydraulic system 10 is reached and for separating this connection when an adjustable lower charging pressure in the hydraulic system 10 is reached, is provided with a control piston 42, which in one of its two switching positions breaks the connection between the inlet P and outlet T and in the other switching position makes this connection. By means of a separating device, a control connection B connecting the hydraulic system 10 to the accumulator charging valve can be separated from the outlet T. On reaching the adjustable upper charging pressure, by means of at least one sealing part of the separating device, the connection forming a leakage point between the control connection B and the outlet T can be sealed hermetically. Due to this arrangement, inside the valve, in the range between the lower and the upper charging pressure, the hydraulic system 10 can be shut off in a completely non-leaking manner.
