摘要
以光皮树果实油脂通过皂化反应获得的皂类为研究对象,利用微波裂解选择性加热优势开展皂类脱羧制备烃类燃料研究。通过气质联用等方法对裂解产物的分析表明,单纯钠皂微波裂解所得到液态产物一般都在皂类干质量的70%以上,裂解液态产物的密度为0.850～0.875 g/cm3,运动粘度为2.09～2.85 mm2/s,与柴油的性质基本相似。裂解液态产物中最高峰是十五碳烯,证实脱羧是皂类微波裂解的主要反应形式。
In order to prepare hydrocarbon fuel,sodium soap made from Swida wilsoniana fruit oil was chosen as a model compound with significant molecular polarity for preparing hydrocarbon fuel by microwave-assisted pyrolysis.The result showed that the hydrocarbon content were usually above 70%.In addition,its density and dynamic viscosity were 0.850～0.875g/cm3 and 2.09～2.85mm2/s,respectively,similar with petroleum diesel.The highest peak in the GC-MS profile of liquid product was fifteen carbon alkenes,decarboxylation was proved to be main reaction in microwave-assisted pyrolysis.
