利用酶解木质素（EHL）部分取代苯酚制备酚醛树脂。研究了木质素取代率对木质素改性酚醛树脂性能的影响。木质素替代量为60%，不影响酚醛树脂的粘接强度。FTIR分析表明，EHL的加入对树脂的化学结构没有太大影响，但导致其耐热性变差。将LPF树脂与生物乙醇生产残基改性酚醛树脂（RPF）进行比较，结果表明该纯化工艺有利于其更高的替代应用和更好的胶粘剂性能。(C) 2014韩国工业与工程化学学会。Elsevier B.V.版权所有。
Enzymatic hydrolysis lignin (EHL) was utilized to partially replace phenol for preparing phenolformaldehyde (PF) resin. The influence of lignin substitution rate on the properties of the lignin-modified phenol-formaldehyde (LPF) resin was investigated. Lignin substitution of 60 wt% did not deteriorate the adhesive strength of PF resin. FTIR analysis of the resins revealed that the incorporation of EHL made no big difference in chemical structure, but led to a deteriorated thermal resistance. The comparison between LPF and bio-ethanol production residue-modified phenol-formaldehyde (RPF) resins elucidated that the purification process was beneficial for its higher substitution application and better performance of adhesive.
