摘要
对于以葡萄糖为原料,在催化剂的作用下,通过加氢裂解得到含有1,2-丙二醇、乙二醇、2,3-丁二醇、1,2-丁二醇、1,4-丁二醇(以下简称二元醇)、山梨醇、丙三醇、甲酸盐、乙酸盐、乳酸盐以及其他未知物(以下简称重组份)的反应液,采用AminexHPX-87H Lon exclusion色谱柱,以0.006 mol/L的硫酸作为流动相,在流速0.5 mL/min的流量下,经示差折光化学检测器检测,能够将反应液中的二元醇以及重组份完全分离,且均在一定质量浓度范围内呈线性[1]。该方法分析反应液中的二元醇及重组份的回收率在97%～103%之间。本方法能够快速、精确测定反应液中二元醇与重组份的含量。
Taking glucose as raw material,with catalysts,the reaction liguid contained 1,2-propanediol,propylene glycol,glycols,2,3-butylene glycol,1,2-butylene glycol,1,4-butylene glycol（be called binary alcohol,sorbic alcohol,third three alcohol,formic acid for short hereinafter） stopping,（be called restructuring share for short under） acetic acid salt,lactate and others,was got through hydrogenation crauking Adopting Aminex HPX-87H Lon exclusion colour spectrum post,0.006 mol/L sulfuric acid as mobile under flow rate of 0.5 mL/min,by the differential refractive power chemistry detector checks,be able to separate binary alcohol in reaction liquid as well as restructuring share was complete,assume and a linearity without exception within certain mass thickness range.The coefficient of recovery owing method binary alcohol and restructuring share in analysing reaction liquid was 97%~103%.The method was able to determine middle binary reaction liquid alcohol and the contents re-organizing share speedy and accurately.
