基于油脂化学的长链二酯是潜在的有机相变材料,可方便地进行热能存储。高效和绿色方法的发展是制备这些环境友好化合物的重要要求,这些化合物也正在广泛的工业应用中。因此,在目前的工作中,在无溶剂的介质中通过离子液体催化的可分级化学酯化或酯交换反应合成了一系列二元酸酯。使起始化合物二羧酸或其甲酯与脂肪醇或胆固醇分别按1:2的比例反应,并通过FT-IR,1 H NMR和13 C NMR对合成的酯进行表征。
A composition comprised of a component selected from the group consisting of a biobased bis-alkyl succinate and a biobased bis-alkyl sebacate, each derived, for example, from the esterification of biobased diacid such as succinic acid or sebacic acid, and a biobased alcohol and a biobased polyester.

Alpha-phosphato amides useful as antiwear additives for lubricants and liquid hydrocarbon fuels are disclosed. Alpha-dithiophosphato amides and alpha-thiophosphato amides containing sulfur at the alpha position are also useful as extreme pressure additives. Non-sulfur containing alpha phosphato amides and alpha-thiophosphato amides containing oxygen at the alpha position are also useful as friction-reducing additives. The compounds are non-corrosive and effective at relatively low concentrations when compared with common phosphorus-based additives.
