Separation. — The separation of thorium from the rare earth metals with which it is still mixed may be accomplished by three methods (1) the carbonate separation depends on the fact that thorium carbonate is much more soluble in sodium carbonate than the carbonates of the rare earth metals (2) by the fractional crystallization of the mixed sulfates at 15°-20°, crystals of Th(S04)2 8 H20 are obtained at the insoluble end of the series (3) thorium oxalate forms a soluble double salt with ammonium oxalate, while the rare earth oxalates are almost insoluble in this reagent. Some other methods which have been suggested are fractionation of the chromates,4 of the hydrogen alkyl sulfates,5 of the acetates, by the use of sebacic add 6 and hydrogen peroxide.

Similar data analysis was applied also to copolymers of sebacic acid with fumaric acid [40], CPH [61], and trimellitimide derivatives [51]. Based on the HNMR analysis, a FA-FA or SA-SA dimer alternating structure (-SA-SA-FA-FA-SA-SA-FA-FA) was suggested for P(FA-SA) 1 1. In the case of copolymers of the asymmetric trimellitimide comonomer (represented by the letters B1 or B2) with the symmetric comonomers sebacic add or CPH (represented by the letter A), 6 diad sequences were expected to be present in the polymer backbone (A-A, A-Bl, A-B2, Bl-Bl, B1-B2, B2-B2) and they were identified by NMR spectroscopy. Due to partially overlapping peaks in some of the copolymers, some assumptions were made. A typical data from this analysis is shown in Table 14.

However, Dr. Rmke was successful in his attempt to synthesize octane-1,8-diisocyanate from sebacic add and sodium azide. In demonstrating his childlike curiosity, Dr. Bayer added the first few drops of the distillate to 1,4-butane diol and obtained a product which could be drawn into filaments, much like Carothers nylon.

Phthalic anhydride is the difunctional acidic component most widely used for the preparation of alkyd resins. Manufacture of the material is dealt with in Section 10.2.2.3. Phthalic anhydride is preferred in this application on account of its low cost and because it gives rise to resins with good solubility and compatibility characteristics and good film properties. Other dibasic acids and anhydrides, which are used to a lesser extent, include maleic anhydride (Section 10.2.2.2), isopthalic acid (VI), adipic acid and sebacic add (Section 9.2.2).
