    Abstract: Methanol and carbon monoxide are fed to a liquid reaction system (3) containing a carbonylation catalyst system through feeding lines (17) and (19), respectively, a part of the reaction mixture containing the resulting acetic acid is withdrawn from the reaction system and is fed to a flash distillation column (4) while maintaining the liquid surface of the reaction system at a constant level, and a high boiling point fraction containing the carbonylation catalyst system is separated by the flash distillation and recycled to the reaction system (3) through a recycle line (21). In the recycle line (21), flow rate and temperature are measured by means of a flow sensor (F3) and a temperature sensor (T2), respectively. The temperature of the high boiling point fraction to be recycled is controlled by a temperature adjusting unit (6) utilizing a controlling unit (8) on the basis of the data measured above, so as to suppress the variation of the temperature and pressure of the above reaction system.

    Abstract: A dissolution testing system comprises a vessel plate on which a plurality of vessels are mounted. Each vessel including a lateral wall having an outer surface around which a plurality of flexible heater elements are attached. Each heater element includes a transparent surface area, a heat conductive element extending along the transparent surface area, a temperature sensing element extending along the transparent surface area, and an electrical contact element connected to the heat conductive element and the temperature sensing element. The transparent heater element allows unobstructed view into the interior of its vessel, and reduces the time required to achieve a stabilized set point temperature in the vessel. A heater control system communicates with each heat conductive element and each temperature sensing element through a corresponding one of the electrical contact elements. The heater control system permits each vessel to be controlled independently of the other vessels.

    Abstract: The invention relates to a method for continuously producing cross-linked, fine-particle geleous polymerizates by copolymerizing: a) water-soluble, monoethylenically unsaturated monomers; b) 0.001 to 5 mol %, with regard to monomers (a), of monomers containing at least two ethylenically unsaturated double bonds, and; (c) 0 to 20 mol %, with regard to monomers (a), of water-insoluble monoethylenically unsaturated monomers in 20 to 80 wt. % of an aqueous solution in the presence of an initiator and at temperatures ranging from 0 to 140 DEG C, whereby the aqueous solution of the monomers, together with the initiator and an inert gas, are continuously fed to a kneader-mixer having at least two shafts which rotate parallel to the axis. A number of kneading and transport elements are situated on the shafts and deliver the substances, which are added at the entry to the kneader-mixer, in an axial direction to the end of the mixer. The inventive method is characterized in that the proportion of the heat dissipation effected by evaporating water out of the reaction mixture equals at least 5 % of the reaction heat, and the proportion of the heat dissipation effected by product discharge equals at least 25 % of the reaction heat, and the remaining heat dissipation is effected by cooling the reactor walls.
