ABSTRACT = {The plasticizer is an important polymer material additive. Non-toxic
and environmentally friendly plasticizers are developed recently in order to
decrease fossil fuel reserves, serious environmental pollution and the toxicity of
phthalate esters. In this study, a new, efficient and environmentally friendly plasticizer of hydrogenated rosin dodecyl ester was prepared by an esterification reaction of hydrogenated rosin and dodecanol. The influences of different reaction
conditions (including different catalysts, the catalyst concentration, the ratio of
the reactants, reaction temperature, and reaction time) on the esterification yield
are examined and discussed. Hydrogenated rosin dodecyl ester with 71.8% yield
was synthesized under the optimized reaction conditions (1:0.8 molar ratio of
rosin to dodecanol, 1 mol% tetrabutyl titanate concentration, and 210°C for
6 h). The esterification reaction is a second-order reaction, and kinetic calculations
showed that the activation energy is 39.77 KJ·mol<sup>−1</sup>
. The structure of the hydrogenated rosin dodecyl ester was confirmed by FT-IR spectroscopy and <sup>13</sup>C NMR
spectrum. Besides, the thermal stability of target product (hydrogenated rosin
dodecyl ester) was also tested by thermal gravimetric analysis (TGA), which
showed a good thermal stability.},
