Title: Improvements in the regeneration of anion-exchange resins
IPC: B01D15/04
Filed: 1958-01-17
Abstract: Acrylonitrile in a waste liquor resulting from acrylonitrile polymerisation is freed from surfaceactive agent such as sodium lauryl sulphate by treating with an anion-exchange resin, after which it can be removed by distillation.  The resin specified is a vinyl pyridine-divinyl benzene copolymer quaternised with dimethyl sulphate.ALSO:Anion-exchange resins which have become depleted with high molecular organic ions derived from surface-active agents are regenerated by acid hydrolysing agents.  The process is applied particularly to the waste liquor resulting from acrylonitrile polymerisation, the liquor containing the monomer and a surface active agent such as sodium lacryl sulphate.  Examples describe the regeneration of a vinyl pyridine-divinyl benzene copolymer quaterised with dimethylsulphate after removal of sodium lauryl sulphate from a 0,1% aqueous solution, using hydrochloric and sulphuric acids, and comparing with treatment with sodium chloride, sodium hydroxide and potassium hydroxide.  The freed fatty alcohol is removed from the resin bed by washing with acetone, ethanol, hexane, benzene, ether or carbon tetrachloride, or with aqueous solutions of emulsifying agents such as alkyl phenolethylene oxide condensates or quaternary ammonium type detergents.

A frame having rims, a bridge and side arms is moulded as an integral unit from a plastic capable of molecular orientation by cold pressing or rolling, and subjecting the portion interconnecting each side arm and the associated rim to molecular orientation by cold pressing or rolling to give the said portions sufficient strength and resiliency to cause grip to the head of the wearer and to permit the arms to fold inwards to a flat position when out of use, thus obviating the need for hinges. Suitable plastics referred to are polyamides, polyurethanes, high molecular polyesters, polyvinylchloride and polyvinylidenechloride. Where the frame is of transparent plastic the eye-pieces may be moulded integral therewith. The Specification as open to inspection under Sect. 91 describes also a frame of plastic in which, instead of cold pressing or rolling, the interconnecting portions are flattened and either slotted or twisted to permit bending. This Specification also describes a metal frame in which the bridge, rims and side arms are made separately and formed by welding or soldering, or in which rims and arms are in one piece and the bridge joined thereto or, as shown in Fig. 4 (Cancelled), the portions 1; 2 and 3 are in one piece and the lower portions of the rims joined thereto by screws or by welding.

[Also in Group XL (c)] Dielectric walls are characterized in that they include a layer comprising partition walls of dielectric material, arranged substantially at right angles to the plane of the layer so as to divide the layer into spaces, and bodies of cellular dielectric material filling the spaces enclosed by said partition walls, said cellular material comprising cell walls having a dielectric constant of such value that the effective dielectric constant of cell walls and voids is approximately equal to the dielectric constant of said partition walls. This structure may have a rigid skin material of approximately equal dielectric constant laminated to one or both sides. The partition walls may be of fibre glass-phenolic resin material. The cellular material may be of foamed plastics (e.g. silicone rubber), hollow beads, small enclosed prisms, foamed ceramic, glass bubbles, exploded mica, pearlite, or incompletely sintered dielectric powders, loaded with particles of material having a high dielectric constant, e.g. polymeric electrolytes, titanates, metals (e.g. aluminium), carbon black, or graphite, which may be insulated from one another, e.g. by coating them with magnesium stearate. The skin layers may be " plastic laminates of resins and fabrics," ceramic plates, rubber sheeting, wood or glass. In one embodiment, the partition walls are arranged in honeycomb style and are cemented to skin sheets on both sides, the cellular material filling the honeycomb spaces. In another embodiment a skin layer carries ribs extending through the foam layer to its opposite surface.
