[目的]对板栗苞液化技术进行研究。[方法]对氢氧化钠、碳酸钠、醋酸（99.5%）、磷酸（85%）、盐酸（37%）和硫酸（98%）6种催化剂对板栗苞液化的影响进行研究,并分析在130、150和170℃液化反应温度下,浓硫酸、磷酸和浓盐酸加入量与苯酚的百分比为1～6%时,对板栗苞苯酚液化效果的影响。对150℃时,以加入量为4%的浓硫酸催化板栗苞苯酚液化产物与甲醛制成的树脂和传统酚醛树脂的性能进行分析。[结果]酸对板栗苞苯酚液化有较好的催化作用,且酸性越强对板栗苞苯酚液化催化效果越好;当反应温度为150℃,催化剂为4%浓硫酸是,板栗苞的苯酚液化效果最佳,液化率可以达到92.11%;当板栗苞粉与苯酚质量比为1∶3时,液化所得产物与甲醛反应所得酚醛树脂基本符合GB/T14732-93的要求。[结论]板栗苞液化制备酚醛树脂是可行的。

[Objective]This paper aimed at studying the liquefaction technology of chestnut shells [Method]Effects on chestnut shells liquefaction of six catalysts were studied,which were sodium hydroxide,sodium carbonate,acetic acid（99.5%）,phosphoric acid（85%）,hydrochloric acid（37%）,sulfuric acid（98%）.The research had analyzed the liquefaction effects of chestnut shells in presence of phenol and at liquefaction temperatures of 130,150 and 170 ℃,in which the proportion of added quantities of concentrated sulfuric acid,phosphoric acid,concentrated hydrochloric acid to phenol were 1%-6%.Properties of phenolic resin made from formaldehyde and phenol-liquefied products of chestnut shells catalyzed by concentrated sulfuric acid with an added amount of 4% at 150 ℃（WPF）were analyzed and compared with traditional phenolic formaldehyde resin（PF）.[Result]Acid catalysts were better than alkaline ones in the phenol-liquefaction of chestnut shells,and the liquefaction ratio increased with the increasing of acidic intensity.The liquefaction ratio had attained the maximum as 92.11 % when catalyzed by concentrated sulfuric acid with an added amount of 4% at 150 ℃.The phenolic resin made from the liquefied products of chestnut shells was basically in accordance with the standard of GB/T 14732-93 when the mass ratio of chestnut shells powders to phenol was 1∶3.[Conclusion]It was possible to produce phenolic resin with liquefied chestnut shells.
