| 摘 要： | 生物油的反应活性是制备生物油-PF(酚醛树脂)的关键因素。首先利用酚单体取代基共轭效益参数(Rc)评价了生物油中主要酚类物质的理论反应活性,然后测定了生物油/甲醛的实际反应能力,并与苯酚/甲醛的反应能力进行了对比,以此来评价生物油的整体反应活性。结果表明:生物油中酚类物质的理论反应活性为苯酚的29%;在10 g生物油中加入2.0 g NaOH,并且当反应温度为80℃和反应时间为90 min时,生物油的实际反应能力是苯酚的31%左右。

| Abstract: | The reactivity of bio-oil is a key factor of preparing bio-oil-PF(phenolic resin).First,the theoretical reactivity of main phenolic compounds in bio-oil was evaluated by Rc(onjugative effect parameter for substituent group of phenolic monomer).Then,the actual reactivity between bio-oil and formaldehyde and the actual reactivity between phenol and formaldehyde were tested and compared,which compared results could evaluate the overall reactivity of bio-oil.The results showed that the theoretical reactivity of phenolic compounds in bio-oil was 29% of pure phenol.The actual reactivity of bio-oil was about 31% of pure phenol when NaOH was 2.0 g in 10 g bio-oil,reaction temperature and reaction time were 80 ℃ and 90 min respectively. |
