Abstract: Diphenylolpropane, i.e. b ,b -bis-(4-hydroxyphenyl)-propane, prepared by condensing phenol with acetone in the presence of an acid condensing agent, is purified by neutralizing the condensing agent in the crude product, dissolving the latter in a water-immiscible organic solvent at elevated temperature, separating the mixture into an aqueous and an organic phase at elevated temperature, and crystallizing the diphenylolpropane from the organic phase.  In a modification, the crude product is mixed with water and the water-immiscible solvent, the acid condensing agent in the mixture is neutralized and the mixture then heated to dissolve the crude product, followed by a separation of the phases and crystallization as above.  Neutralizing agents are aqueous solutions of alkali-metal hydroxides, carbonates or bicarbonates or ammonia.  Water-immiscible solvents are hexane, gasoline, benzine, benzene, toluene, ethylene dichloride, trichlorethylene, methylene chloride and chloroform, and mixtures thereof.  Carbon tetrachloride is not suitable.  The organic solvent mother-liquors may be used to purify several consecutive portions of diphenylolpropane and may then be worked up by distillation or extraction with alkali-metal hydroxide solution to recover unused phenol.  In the preparation of diphenylolpropane, known acid condensing agents are used and additives known to promote the condensation, such as mercapto-substituted carboxylic acids or salts or esters thereof, mercaptols or mercaptals, acid boron compounds or calcium chloride, may be present.  In examples, diphenylolpropane is made and purified using as a solvent: (1) ethylene dichloride; and (2) a mixture of ethylene dichloride and benzene.  Specification 647,063 is referred to.

Abstract: 619,260. Moulding tyres on to toy wheels. CARTNER, J., and JACKSON, J. M. Nov. 28, 1946, No. 35358. [Class 87 (ii)] [Also in Group XV] A wheel 10, Figs. 1, 5, and a two-part mould 23, 24, are so formed that the action of securing the mould halves together about the wheel causes displacement of an annular portion of the wheel to form a peripheral seal between the mould and wheel which prevents the moulding material from leaking over the side faces of the wheel. In one form of the invention the wheel 10 is made from die-cast material such as that known under the Registered Trade Mark " Mazak " or from a plastic material and is provided with a peripheral projection 11 about which the tyre of rubber or other plastic material is to be moulded, the side face 15 being undercut as at 18 to form a wedge-shaped annular ridge 19. The opposite face 16 may also be formed with an annular slope 20 so that it forms a relatively sharp angle with the periphery of the wheel. On securing the mould halves 23, 24 together symmetrically about the wheel 10 located on a pin 22 in the lower half 23 of the mould, the ridge 19 collapses and forms a seal between the two halves of the mould and the side faces 15, 16 of the wheel 10. Alternatively instead of providing the ridge 19 on the wheel, a sharp annular upstanding ridge 32, Fig. 6, is provided in the mould cavity in the upper half 24 of the mould in such a way that when the mould halves are brought together, the ridge 32 cuts into the side face 15 of the wheel, thus effecting a seal.
