摘要
Abstract
Using a stirring-heating approach,six deep eutectic solvents(DESs)were synthesized with menthol as the hydrogen bond acceptor and valeric acid,hexanoic acid,palmitic acid,myristic acid,lauric acid,and stearic acid as hydrogen bond donors.These six low-melting solvent samples were characterized by FT‑IR and ¹H NMR spectroscopy,and their catalytic performance in the synthesis of pentaerythritol isooctanoate was systematically investigated under various conditions.Through process optimization and response surface analysis,the optimal reaction conditions were determined as follows:reaction time of 7 h,alcohol‑to‑acid molar ratio of 1:4.8,and catalyst loading of 1.5 wt.%.Under these conditions,an esterification rate of 90%was achieved.Performance evaluation revealed that the synthesized pentaerythritol isooctanoate exhibits a high viscosity index,a low pour point,and favorable low‑temperature fluidity.Thermal analysis further indicated that the compound possessed notable thermal stability.关键词
