Charles, J. Mustafa, S. Osman] The reaction of hydrogen bromide (HBr) with long chain triol acids has been investigated in some detail. The 9, 10, 12-trihydroxy stearic acid (I) on treatment with HBr yielded three products, namely 9(10)-bromo-10(9)-hydroxy-12-bromo (III), 9(10)-bromo-10(9)acetoxy-12-bromo (IV) and 9,10-dibromo-12-hydroxy (V) stearic acids. When 9,12,13-trihydroxy stearic acid (II) was subjected to the same reaction under similar conditions, 12,13-dibromo-9-hydroxy (VI), 12(13)-bromo-13(12) acetoxy-9-bromo (VII) stearic acids were obtained. The structure of these products were established on the basis of their elemental values, spectral data and chemical evidence.
