摘要
采用全因素试验法，对马尾松木材进行过热乙醇溶液脱脂处理，以获取马尾松木材高效脱脂工艺技术。试验结果显示：（1）脱脂温度对马尾松松脂溶出量的影响极显著，且溶出量随着脱脂温度的升高而增大；（2）脱脂时间对马尾松松脂溶出量的影响极显著，且溶出量随着脱脂时间的延长呈先增大后减小的趋势；（3）脱脂浴比对马尾松松脂溶出量的影响极显著，且溶出量随着脱脂浴比的延长呈先增大后减小的趋势；（4）利用过热乙醇溶液对马尾松木材进行脱脂，其最佳工艺是脱脂时间为130℃、脱脂时间为8h、浴比1：8。
Based on the all-factors method, Masson pine wood would be degreased in the superheat 5% ethanol solution in order to get a ideal deresination technology. The results were following as： （1） The extraction mass is the most remarkably influenced by the extracting temperature. With the heighten of the temperature, the extraction mass increase; （2） The extraction mass is the most remarkably influenced by the extracting time. With the lengthen of the temperature, the extraction mass increased, and then decreased; （3） The extraction mass is the most remarkably influenced by the extracting Vwood/Vrolution. With the growth of the extracting Vwood/Vrolution, the extraction mass increased, and then decreased; （4） The ideal deresination technology is 130℃, 8h extracting time, 1 ： 8 Vwood/Vrolution and 5% ethanol solution.
