| 摘 要： | 为了满足游离细胞催化、多级膜生物反应器连续转化生产丙烯酰胺的新工艺对丙烯酰胺和丙烯腈浓度进行监控的需要，分别提出了采用阿贝折射仪快速分析丙烯酰胺和定时进样气相色谱外标法快速分析丙烯腈浓度的新方法。与传统的丙烯酰胺和丙烯腈的气相色谱内标方法相比，新方法在保持原有气相色谱分析精度的基础上，显著提高了分析的时效性，可以对各级成分变化做准确及时的分析和监控，从而保证了多级膜反应器连续转化过程的操作稳定性。

| Abstract: | A new technique for producing acrylamide,in which continuous bioconversion of acrylonitrile was accomplished using multi-stage membrane bioreaction with free cells as biocatalyst has been developed.For meeting the demand of stable operation of the continuous process,a novel refraction method and timed gas chromatography(GC) were respectively constructed to quickly and accurately analyze the concentration of(acrylamide) and acrylonitrile in different stages.Compared with the original internal-standard GC,the refraction method and the timed GC method not only maintained the accuracy but also highly improved the time(efficiency),thereafter ensured the operation stability of the new continuous bioconversion of acylamide. |
