摘要

以工业级甘油为原料,合成了一、二、三乙酰甘油(MDTAG),作为生物柴油工业生产中甘油的替代品。酯化反应以摩尔比(醋酸:甘油1:6)进行,在实验室条件下,加入甲苯作为拖拽剂,定期去除反应中的水分。采用离子交换树脂作为多相催化剂。利用红外光谱(FT-IR)对mdtag进行了表征。用差示扫描量热法(DSC)分析了其低温行为。实验得到的MDTAG在0℃以下的温度下表现出优异的性能。这一结果使得MDTAG有可能被认为是改善(从改性植物油中)生物润滑油基低温流动性的添加剂。

Synthesis of mono di tri acetyl glycerols from glycerin technical degree
Mono, di, tri acetyl glycerols (MDTAG) were synthesized from technical grade glycerin , as an alternative for the use of glycerol generated by the biodiesel industry. The esterification, was done using molar ratio (acetic acid: glycerin 1:6), at laboratory scale, toluene was added as a dragging agent to periodically remove the water of the reaction. Ion exchange resin was used as a heterogeneous catalyst. MDTAGwere characterized using infrared spectroscopy (FT-IR). The low temperature behavior was analyzed by means of differential scanning calorimetry (DSC). MDTAG obtained experimentally showed excellent performance at temperatures below 0°C. This result makes MDTAG potentially considered as additives to improve the low-temperature fluidity of biolubricant bases (from modified vegetable oils).
