Solidification point curves of binary acid mixtures: VI. Tetratriacontanoic-hexatriacontanoic acids

With the synthesis ofn-hexatriacontanoic acid (sol. pt. 99.65°C.), this time coupling ω-carbethoxynonoyl chloride with cadmium docosyl bromide, rather than with its zine iodide counterpart (5d), to formn-dotriacontanoic acid, from which by malonic-ester synthesis, the chain was lengthened in two stages, the series of solidification point eurves of binary mixtures of the homologous acids in question has been increased by one pair. Detailed descriptions of the several steps involved in these syntheses have been given. The curve, although slightly flatter—it is here drawn to a different scale than that previously used (5)−has the same general shape as those previously reported for the homologous fatty acids in this area.
