以酒石酸为拆分剂,从外消旋2-氨基丁醇中拆分出( D)-2-氨基丁醇和( L)-2-氨基丁醇。考察了不同的溶剂对2-氨基丁醇拆分的影响,最终选取了正丁醇作为拆分溶剂。并对反应时间,反应温度,溶剂体积对拆分的影响进行了考察。在最优条件下, D-2-氨基丁醇的总收率达到83.69%,旋光达到9.9°。
以酒石痠為拆分劑,從外消鏇2-氨基丁醇中拆分齣( D)-2-氨基丁醇和( L)-2-氨基丁醇。攷察瞭不同的溶劑對2-氨基丁醇拆分的影響,最終選取瞭正丁醇作為拆分溶劑。併對反應時間,反應溫度,溶劑體積對拆分的影響進行瞭攷察。在最優條件下, D-2-氨基丁醇的總收率達到83.69%,鏇光達到9.9°。
이주석산위탁분제,종외소선2-안기정순중탁분출( D)-2-안기정순화( L)-2-안기정순。고찰료불동적용제대2-안기정순탁분적영향,최종선취료정정순작위탁분용제。병대반응시간,반응온도,용제체적대탁분적영향진행료고찰。재최우조건하, D-2-안기정순적총수솔체도83.69%,선광체도9.9°。
D-2-amino-butanol and L-2-amino-butanol were separated from the DL-2-amino-butanol by the tartaric acid as the resolving agent. The effects of different solvent on the separation of 2-amino-butanol were investigated. Finally, butyl alcohol was chosen as the split solvent. The effects of reaction time, reaction temperature, and volume of solvent were also investigated. Under the optimized conditions, the final yield of D-2-amino-butanol was 83. 69% and polarimetry was 9. 9 °.
