摘要/Abstract

摘要： 以龙脑樟枝叶为原料，研究了天然冰片提取的清洁生产工艺。先将提取装置中的单级冷凝改为两级分段冷凝，并将提取冷凝液及蒸馏釜液一并套用至下次提取过程中，着重探讨了套用次数对天然冰片收率及其含量的影响，并对蒸馏提取残渣进行厌氧生物处理，考察了其厌氧过程的产甲烷势及其产气规律。结果表明：提取装置中的单级冷凝改为两级冷凝后，其天然冰片的收率为1.11%，纯度为95.23%，产品收率及纯度分别提高了45.42%和5.44%；废液套用20次，天然冰片的收率升至1.28%左右，套用20次的天然冰片纯度为95.09%，且废水排放量减少了99%；残渣的产甲烷量为31.5mL/g，蒸馏提取残渣适合进行厌氧生物处理。

Abstract: The clean production process of Natural Borneol by extraction from Cinnamomum Camphora was studied. The single-stage condensation in the extraction apparatus was replaced by two-stage condensation. The distillate and residual liquid were combined and reused in the next extraction process. The effect of recycle times on yield and purity of borneol was studied. The residue of flask was treated by anaerobic process. The biochemical methane potential (BMP) and the methane production rules in the anaerobic process were obtained. The results show that the yield and purity of borneol are respectively 1.11% and 95.23% at the two-stage condensation,improved by 45.42% and 5.44% compared with the single stage condensation. The yield of borneol was improved to 1.28% until 20 times of reuse of waste water. The purity of borneol of 20 times reuse is 95.09%. The discharge of the waste water was reduced by 99% through the reuse of the residual liquid and distillate. The BMP of residue is 31.5mL/g. The anaerobic process is suitable for the treatment of residue.
