N-(benzoyl) stearic acid hydrazide was synthesized from benzoyl hydrazine and stearyl chloride which was deprived from stearic acid via acylation. The structure of the compound had been characterized by FT-IR, 1H NMR, at the same time, the structure of N-(benzoyl) stearic acid hydrazide was optimized by the semiempirical method PM3. The influence of the reaction ratio, reaction time and reaction temperature to the yield of N-(benzoyl) stearic acid hydrazide was investigated by orthogonal experiment, and the optimized reaction condition was molar ratio of benzoyl hydrazine: stearyl chloride 1:1, reaction time 6 h, reaction temperature 70°C, and the yield was 92.9%. The TGA thermal analysis of N-(benzoyl) stearic acid hydrazide showed that thermal stability of N-(benzoyl) stearic acid hydrazide was affected by heating rate, and the N-(benzoyl) stearic acid hydrazide enhanced the tensile strength, modulus and elongation at break of Poly(L-lactic acid)(PLLA)
