Ni, Zihao published the artcileReaction kinetics analysis of branched-chain alkyl esters of palmitic acid and cold flow properties, Recommanded Product: Isobutyl palmitate, the publication is Renewable Energy (2020), 147(Part_1), 719-729, database is CAplus.
Preparation of Me palmitate, iso-Pr palmitate, iso-Bu palmitate, and isoamyl palmitate was carried out using pyridine Bu bisulfate ionic liquid as catalyst in a self-designed reactor to catalyze esterification reaction of palmitic acid with methanol, isopropanol, isobutanol, and isoamyl alc., resp. According to the single-factor exptl. results, an orthogonal test of four factors and three levels was carried out for branched-chain alkyl esters of palmitic acid under different reaction time, reaction temperature, and catalyst dosage. Verification test was conducted under the optimal conditions, and the conversion in all the cases was up to 97%. Anal. of the reaction kinetics of Me palmitate, iso-Pr palmitate, iso-Bu palmitate, and isoamyl palmitate was carried out by the integral method. Reaction order, frequency factor, activation energy, and reaction kinetic model were determined Compared to Me palmitate, the kinematic viscosity of the branched-chain alkyl esters of palmitic acid was slightly higher; however, the solidifying point (SP) and cold filter plugging point (CFPP) decreased with increasing degree of branched-chain. The CFPP reduced by up to 15°C. Therefore, the use of branched-chain alc. instead of methanol ester exchange descaling method can effectively reduce the SP and CFPP of biodiesel to improve its cold flow properties.
