【摘要】 本文研究了层析、D031、001×7聚苯乙烯—二乙烯基苯磺酸型阳离子交换树脂和它们的H⁺、NH₄⁺、Co²⁺、Ba²⁺、Ak³⁺、Fe³⁺或Cr⁺³等离子基型对木糖醇和山梨糖醇的柱层析分离效果。结果表明,层析H⁺、Fe³⁺型和D031H⁺型树脂能有效地分离木糖醇和山梨醇。最适宜温度均为55℃,最适宜洗脱液流量:层析H⁺及Fe³⁺型树脂分别为4.8ml/min和2.8ml/min,D031H⁺型为3.0ml/min。以10^-3mol/dm³的十二烷基硫酸钠的3％正丙醇溶液为洗脱液能明显提高分离能力。更多还原

【Abstract】 In this paper, separation of xylitol and sorbitol was effected by column chromatography using a sulfonated lystyrene-divinylbenzene ation exchange resin, in H+, NH4+, Co2+, Ba2+, Al3+, Fe3+or Cr3+ form. The result showed that xylitol and orbitol can be separated ffectivelly, by using chromatographic H+, Fe3+and D031 H+ form resin, Optimal temperature for separation is 55℃.The most suitable eluant low rate for chromatographic H+ and Fe3+ type is 4.8ml / min and 2.8ml / min respectivaly and for D031 H+type 3.0ml/min.The efficiency of eparation can be improved remarkably by using eluant containing 10-3 mol/dm3 sodium dodecyl sulfate (SDS) in 3% n-propyl alcohol.更多还原
