摘 要:采用一步键合法制备以烯丙基-β-环糊精和改性纳米氧化钇为单体的有机-无机杂化整体柱,并考察了改性纳米氧化钇用量、反应温度和反应时间对整体柱制备的影响。通过IR、N2吸附-脱附、SEM和EDS对整体柱柱内固定相进行表征。整体柱内固定相与柱壁键合紧密,有较大的孔径,改性纳米氧化钇均匀地分布在固定相中;整体柱具有良好的通透性和机械强度。运用该整体柱拆分盐酸地匹福林对映体和盐酸卡替洛尔对映体,两种手性药物均达到基线分离,说明该整体柱具有良好的手性拆分能力。Organic-inorganic hybrid monolithic column was prepared by one-step reaction method,using allyl-β-cyclodextrin and modified nanosized-yttrium oxide as the monomers.And the effects of the dosage of modified nanosized-yttrium oxide,reaction temperature and reaction time were investigated in prepared monolithic column process.The stationary phase of monolithic column was characterized by IR,N2 adsorption-desorption,SEM and EDS.The results showed that the internal stationary phase was close to the column wall,had a larger pore size and uniform distribution of the modified nanosized-yttrium oxide. The monolithic column had good permeability and mechanical strength. The enantiomers of hydrochloric dipivefrin and hydrochloric carteolol were separated using the self-prepared monolithic column.And two kinds of chiral drugs reached the baseline separation,which indicated that the monolithic column had good chiral resolution ability.
