a mixture of amyl alcohols and propanol and butanol formed from distillation of fermented liquors

The results showed that the relative contents of fusel oil were decreased; the relative contents of total ester, total acid and phenylethyl alcohol increased after PEF treatment.

研究结果表明：经一定条件的高压脉沖电场处理后，葡萄酒中的杂醇油含量有所下降，总酸、总酯和苯乙醇的含量有所上升。

In this paper, the properties, the extraction, and the purification and separation of fusel oil and the application of fusel oil were illustrated.

阐述了杂醇油的性质、产生原因和提取、提纯分离技术以及应用。

With the development of analytic techniques, the analytic methods of fusel oil in liquor could be further improved.

随着分析技术的发展，对白酒中杂醇油的分析方法在进一步的改进。

It is reported that fusel oil can be used for synthesising mixing esters mainly inclusding amyl acetate when it is heated and back-flowed with Catalyst oil of vitriol or canon exchange resin.

本文报告了以酒厂废料杂醇油为原料，在催化剂浓硫酸或阳离子交换树酯存在下，经加热回流与冰醋酸反应生成以乙酸异戊酯为主的混合酯。

Traditional dehydration techniques of fusel oil included constant boiling dehydration, salting-out dehydration and molecular sieve absorption dehydration.

传统的杂醇油脱水工艺有：恒沸脱水法、盐析脱水法和分子筛吸附脱水法。

By using efficient padding, fusel oil was exactly distilled twice after being preliminarily dealt with. And then we got highly pure 2-methyl -1-butanol and (S)-(-)-2-methyl -1-butanol.

采用高效填料，通过对预处理后的杂醇油进行两次精密精馏，得到了高纯度的2-甲基-1-丁醇和（S）-（-）-2-甲基-1-丁醇。
