The empirical solubility of hydrocarbon fluids, polyalphaolefin (PAO) and mineral oil, in thirteen small molecular weight alcohols (C-C) was determined. Butanols, pentanols, and 1-hexanol could dissolve up to PAO-10 and mineral oil. -Pentanol and 1-hexanol could also dissolve high-viscosity PAO-150. The dialkyl carbonate of fusel oil (DFC) was synthesized from dimethyl carbonate in 69% yield. DFC had excellent non-polar solubility and could dissolve PAO-150 and several common industrial lubricants. The flash point of DFC was 93 °C, more than twice that of isoamyl alcohol. DFC had net heating value of 30.47 MJ kg, nearly double that of dimethyl carbonate. However, its derived cetane number of 22.8 indicates DFC could not be used directly as diesel fuel.
测定了烃类流体、聚α-烯烃（PAO）和矿物油在13种小分子量醇类（C-C）中的经验溶解度。丁醇、戊醇和1-己醇最多可溶解PAO-10和矿物油。-戊醇和1-己醇也能溶解高粘度的PAO-150。由碳酸二甲酯合成了杂醇油碳酸二烷基酯（DFC），产率为69%。DFC具有优异的非极性溶解性，能溶解PAO-150和几种常见的工业润滑剂。DFC的闪点为93℃，是异戊醇闪点的两倍多。DFC的净热值为30.47 MJ/kg，几乎是碳酸二甲酯的两倍。然而，其衍生十六烷值为22.8，表明DFC不能直接用作柴油燃料。
