摘要
以糖类为原料采用发酵法生产甘油是甘油来源的一条重要途径。发酵完成后 ,甘油的提取技术一直是一个难题。采用连续色谱分离技术代替传统的减压蒸馏提取技术较好地解决了上述难题 ,使甘油的提取率由 6 0 %提高到 95 %以上 ,甘油纯度达到 98.5 %～ 99.5 % ,进一步减压蒸馏可得到 99.9%的高纯度甘油。
Sugar fermentation is one of the important ways to produce glycerol.It is still a problem to recover the glycerol by vacuum distillation from the fermentation broth in the process.In this paper,we adopt the continuous chromatographic technology to replace the traditional rcovery methodvacuum distillation.The recovery of the glycerol is improved from 60% to 95%,and glycerol purity can reach 98.5to99.5%.
