摘要
在9.33kPa、釜温<100℃条件下,用26块理论塔板数的分馏柱,用减压分馏法将正戊醛与2-甲基丁醛分离,正戊醛收率80%,纯度≥98%;2-甲基丁醛收率68%,纯度≥98%。还探讨了阻聚剂对戊醛异构体分馏结果的影响。
Under conditions of 9. 33 kpa, < 100'℃and the fractional distillation column with 26 therotical paate numbers, the vacuum distillation method is used to separate n-valeraldehyde from 2-methylbuturladehyde, The yieldof n-valeraldehyde is 80% with a purity of ≥98%;the yield of 2-methylbutyaldehyde is 68% with a purity of ≥98% The effect of ploymerization inhibitor on the fractional distillation result of valeraldehyde isomers is discyssed in the paper,
