摘要:
为了研究氧化预处理对后续酯化效果的影响,利用生物油模型化合物进行了氧化预处理以及酯化实验.以糠醛、乙酸、丙酮、乙醇配制模型化合物,选取过氧化氢、臭氧为氧化剂进行氧化处理实验,通过酸值、GCMS以及红外光谱等分析研究了氧化时间(0~2 h)、过氧化氢量(20~60 mL)、氧化剂种类对氧化处理及后续酯化效果的影响.研究表明:在氧化过程中,增加过氧化氢量能够提高氧化处理能力,但增强效果并不明显;在几种不同的氧化方式中,过氧化氢和臭氧联合氧化为相对较优的氧化处理方式;相比于模型化合物直接酯化的酯含量7.8%,经过氧化处理后,模型化合物酯含量上升到了24.9%及以上.酯化提质前进行氧化预处理,可有效增强酯化效果.
Abstract:
To investigate the influence of oxidative pretreatment on the following esterification, oxidative pretreatment and esterification are tested by using the bio-oil model compounds. Furfural, acetic acid, acetone and ethyl alcohol are chosen to constitute the bio-oil model compound. H2O2 and ozone are used as the oxidizer in oxidative pretreatment. The influences of the oxidative reaction time(0 to 2 h), the amount of H2O2(20 to 60 mL)and the oxidizer type on both the efficiencies of oxidative pretreatment and the following esterification are investigated by acid values, gas chronatography-mass spectrometer(GCMS)and Fourier transform infrared spectroscopy(FTIR). The results show that adding more H2O2 in oxidation can improve the effect of oxidation pretreatment, but by a small amount. Oxidative pretreatment combining ozone and H2O2 is an optimal oxidative method among different oxidative pretreatments. Compared with the esterification rate of 7.8% of bio-oil model compounds without oxidative pretreatment, the esterification rate is increased to no less than 24.9% by using the selected oxidative method. The oxidative pretreatment before esterification can effectively enhance the effect of the esterification.
