  • Patent number: 7371902
    Abstract: Methods for purifying a p,p-bisphenol A generally include distilling a feed stream comprising p,p-BPA in a distillation column at a pressure less than or equal to 20 millibars. The distillation column separates the bisphenol feed stream to produce a light fraction, an intermediate fraction and a heavy fraction. The intermediate fraction comprising the purified bisphenol contains lesser impurities that the p,p-BPA in the feed stream. In one embodiment, the intermediate stream is recovered using a side-draw. The side-draw is located between a first zone and a third zone in the distillation column.

  • Patent number: 7368601
    Abstract: In the stopping and starting operations of a distillation column used for producing (meth)acrylic acids according to the present invention, upon stopping the operation of the distillation column, the heating of a reboiler attached thereto is interrupted and then the reboiler is rapidly cooled; and/or upon starting the operation of the distillation column for production of the (meth)acrylic acids, an inner wall surface of the distillation column is heated to a temperature higher than a condensation temperature of the (meth)acrylic acids and the operation of the distillation column is started under the heated condition. According to the present invention, it is possible to early and safely stop the operation of the distillation column while preventing the occurrence of polymerization within the distillation column, and stably perform an operation for distillation of acrylic monomers for a long period of time.

  • Patent number: 7361725
    Abstract: In this invention, a process of thermal degradation of biodegradable bacterial polyesters poly(hydroxyalkanoate)s (PHAs) to lower molecular weight PHAs in controllable manner has been developed. The process involves using at least one additional component to ‘dilute’ the PHAs in the thermal degradation process, so that the process can be controlled in the senses of better heat transfer, better stirring, easier working up after the reaction. The relationship of processing time and the molecular weights of the products at a certain temperature was obtained so that it is possible to obtain the desired molecular weight products in the real production under the guidance of the relationship.
