The organic esterification reaction of some aromatic carboxylic acids and glycerol in the absence of organic solvents to obtain some α-mono aromate glycerol have been studied. The optimum reaction conditions were determined by esterification of glycerol and benzoic acid to produce α-mono benzoate glycerol (α-MBG). The optimal condition (catalysts and solvents) to get a high selective compounds and high yields have been studied. When use of heterogeneous catalyst (Amberlyst-15) and excess of glycerol (eight time) which plays as a reactive
and solvent getting a required selectivity and high yield (about70%) in comparison to the homogeneous catalysts (H2SO4, CH3SO3H), in addition to the low selectivity of the final product. The reaction followed by using thin layer chromatography (T.L.C), the molecular structures have determinate by spectroscopy methods :FT-IR,1HNMR, 13C-NMR
