Solid alcohols based on waste cooking oil (WCO) and other edible oils (butter or soybean oil) were synthesized by a simple one-step method. The effects of sodium hydroxide (NaOH) dosage and type of oil on the combustion performances were explored. IR spectroscopy and micro-morphologies of the oil based solid alcohols were also studied. Results showed that, for oil based solid alcohol, use of an appropriate excess of NaOH and an oil with lower iodine value produced the solid alcohol with better combustion performance. Centrifugation produced the bottom waste cooking oil (B-WCO) with lower iodine value and the supernatant waste cooking oil (S-WCO) with higher iodine value. The B-WCO afforded solid alcohol with longer combustion time, higher melting temperature and relatively low combustion residue rate, whereas the S-WCO could be used for synthesizing biodiesel.
基于废食用油（WCO）和其他食用油（黄油或大豆油）的固体醇通过简单的一步法合成。研究了氢氧化钠（NaOH）用量和油的类型对燃烧性能的影响。还研究了基于油的固体醇的红外光谱和微观形貌。结果表明，对于油基固体醇，使用适量过量的 NaOH 和碘值较低的油可以制得燃烧性能更好的固体醇。离心得到碘值较低的底部废食用油（B-WCO）和碘值较高的上清废食用油（S-WCO）。B-WCO 提供的固体醇具有更长的燃烧时间、更高的熔点和相对较低的燃烧残渣率，而 S-WCO 可用于合成生物柴油。
