Title: Reflux crystallization
IPC: C07C17/392
Filed: 1969-09-15
Abstract: 1275798 Reflux crystallisation UNION CARBIDE AUSTRALIA Ltd 15 Sept 1969 [18 Sept 1968] 45303/69 Heading BIG. A multicomponent feedstock mixture (solid or liquid) is continuously purified in a solidliquid countercurrent purifier having three sections, a recovery section 2, a refining section 1 and a purifying section 3, the recovery and refining sections being tapered to maintain the relative velocity of the crystal and liquid phases, and an external cooling system consisting, in the embodiments, of jackets through which coolant flows in the opposite direction to the liquid phase in the apparatus such that there is a continuous downward temperature gradient from the base of the cooling section to the opposite end of the recovery section. A heat exchange system is provided for the jackets such as to control the temperature gradient. The feed stock is introduced adjacent the junction of the refining and recovery sections, crystals being transported (by scraper conveyors) to the purifying section, in the opposite direction to that of the reflux liquid. An agitator is provided in the purifying section 3. One embodiment of the apparatus is shown in Fig. 1, the feedstock being introduced at the inlet point 20 and the recovery and refining sections, 1 and 2, being cooled by jackets 10, 11 respectively. Before entry into the purifying section, the crystals are raised over an adjustable weir, the purifying section containing combined heating means and means for removing the product (Fig. 19). This heating means consists of steam heated tubes 147, 148 with a screen surface 140 and an annulus 143 leading to the product outlet 30. All unscraped surfaces of the apparatus are additionally heated, to prevent crystal build-up thereon. A second embodiment of the invention has the refining and recovery sections each in the form of three cylinders of decreasing cross section, these cylinders not necessarily being in line, but optionally placed side by side. In this latter arrangement they may be replaced by open troughs. A further embodiment has the axes of the refining and recovery sections vertical. The examples given are of the separation of para-dichlorobenzene from a mixture containing 75% of the para isomer, and of mixtures of para-dibromo benzene and paradichlorobenzene, alpha-naphthol and naphthalene, beta-naphthol and alpha-naphthol, beta naphthol and naphthalene, para-dichlorobenzene and ortho-dichlorobenzine, and coke oven naphthalene oil.

Title: Process for the preparation ofª,ªÏ-dichloro-polyalkylene oxides
IPC: C08G65/26
Filed: 1965-10-29
Abstract: a ,o  - Dichloro - polyalkylene oxides are obtained by polymerizing tetrahydrofuran or a mixture of tetrahydrofuran and at least one other cyclic ether at -10 DEG  to 70 DEG  C. in the presence of a two component catalyst system consisting of SOCl2 and a Lewis acid selected from antimony pentachloride, stannic chloride and BF3 and its complexes, thereafter deactivating or removing said Lewis acid and heating the reaction mixture.  It is preferred to mix the two components of the catalyst before adding them to the liquid monomer mixture and the reaction may be carried out in an inert solvent or dispersion medium e.g. carbon tetrachloride, ethylene tetrachloride. The polymerization may be terminated by the addition of base, e.g. NH3, H2O, caustic soda, caustic potash, organic amides or amines such as pyridine, picoline or quinoline, or by the removal of the Lewis acid by adsorption on e.g. activated carbon, and filtering the solution.  The filtrate is heated, generally at 60-100 DEG  C. in the presence of SOCl2.  In the examples, cyclic ether monomers specified are ethylene oxide, propylene oxide, oxacyclobutane and 3-chloro-1,2-propylene oxide and boron trifluoride complexes specified as catalysts are boron trifluoride/tetrahydrofuran complex and boron trifluoride/phenol complex.

The end walls 22, 24 are folded-over with a two-ply flange 20 along the edges of the base 10. Diagonally folded flaps 26, Figs. 1, 5 (not shown), on the ends of the outer side walls 14, are glued to the outer end walls 22. The box is transported before erection with the side walls 14, 16 folded-in flat against the base 10, and the end walls 22, 24 extending beyond the ends of the base, Fig. 3 (not shown). Erection is effected by folding- up the end walls 22, 24, Fig. 5 (not shown). The flaps 26 simultaneously draw up the side walls 14, 16. As the latter bend up, the readily tearable fold lines connecting the strips 18 to the inner side panels 16 are pulled apart. The inner end walls 24 are then folded inwards to engage tabs 30 in notches 32 in the inner side walls, and hold the box erect.
