Fast pyrolysis of pine wood was carried out to yield a liquid bio-oil mixture that was separated into organic and aqueous phases. The organic phase (ORG-bio-oil) was characterized by gas chromatography–mass spectroscopy, 31P-nuclear magnetic resonance spectroscopy, and Fourier transform infrared (FTIR) spectroscopy. It was further used as a raw material for producing a mixture of biphenolic compounds (ORG-biphenol). ORG-bio-oil, ORG-biphenol, and bisphenol-A were reacted with cyanogen bromide to yield cyanate ester monomers. Cyanate esters were characterized using FTIR spectroscopy and were thermally cross-linked to develop thermoset materials. Thermomechanical properties of cross-linked cyanate esters were assessed using dynamic mechanical analysis and compared with those of cross-linked bisphenol-A-based cyanate ester. ORG-biphenol cyanate ester was observed to have a superior glass transition temperature (350–380°C) as compared to bisphenol-A cyanate ester (190–220°C). Cyanate esters derived from bio-oil have the potential to be a sustainable alternative to the bisphenol-A-derived analog.

来自木质纤维素生物质的快速热解生物油，用于开发生物基氰酸酯和交联网络

进行松木的快速热解以产生液体生物油混合物，该混合物被分离成有机相和水相。有机相（ORG-生物油）通过气相色谱-质谱、31P-核磁共振光谱和傅里叶变换红外（FTIR）光谱表征。它进一步用作生产双酚化合物混合物（ORG-biphenol）的原料。ORG-生物油、ORG-双酚和双酚-A与溴化氰反应生成氰酸酯单体。氰酸酯使用 FTIR 光谱进行表征，并进行热交联以开发热固性材料。使用动态力学分析评估了交联氰酸酯的热机械性能，并与基于交联双酚 A 的氰酸酯进行了比较。与双酚 A 氰酸酯 (190-220°C) 相比，观察到 ORG-双酚氰酸酯具有更高的玻璃化转变温度 (350-380°C)。源自生物油的氰酸酯有可能成为双酚 A 衍生类似物的可持续替代品。
