摘要

采用氯化胆碱基深度共晶溶剂（DES）对松（海松）木材的萃取成分进行了研究。采用两种不同的共晶混合物（ChCl:Et-Gly；ChCl:Urea摩尔比为1:2）、两种不同提取方法（热水浴、超声辅助提取）、温度（40–60°C）、时间（30–60分钟）和固液比（1:10–1:20 g/mL）参数。为了优化操作条件，进行了田口分析。树脂酸形成了松（海松）木材的化学成分。脱氢枞酸、枞酸和异枞酸是主要的化合物。确定了参数对系统性能的影响如下：DES类型>固液比>提取方法>温度>时间。因此，确定了提取海松木材中亲脂性化合物的最佳条件：乙二醇和1:10固液比在60°C热水浴中提取60min。

Optimization for Green Path in Wood Extractives by Taguchi Analysis

Extractive composition of Pinus pinaster (Maritime pine) wood was studied with choline chloride based deep eutectic solvents (DES). Two different eutectic mixtures (ChCl: Et-Gly; ChCl:Urea 1:2 molar ratio), two different extraction methods (hot water bath, ultrasound assisted extraction), and temperature (40 – 60 °C), time (30 – 60 min.) and solid:liquid ratio (1:10 – 1:20 g/mL) parameters were applied. For the optimization of operation conditions, Taguchi analysis was performed. Resin acids formed the chemical composition of Pinus pinaster (Maritime pine) wood. Dehydroabietic acid, abietic acid and isopimaric acid were found to be the major compounds. The impact of parameters on the performance of the system was determined as follows: DES type > solid:liquid ratio > extraction method > temperature > time. So, for the extraction of lipophilic compounds in Maritime pine wood, the optimum conditions were determined as hot water bath extraction at 60 °C with ethylene glycol and 1:10 solid liquid ratio for 60 min.
