The Isopentyl alcohol and Isobutanol detection in in 19 mulberry varieties were detected. 采用該方法對19個果桑品種釀制的桑果酒的異戊醇異丁醇進行了檢測。

Isopentyl lactate was synthesis from lactic acid and isopentyl alcohol in the presence of ferric chloride hex-ahydrate. 在六水三氯化鐵存在下可以由乳酸和異戊醇合成乳酸異戊酯。

A method to detect Isopentyl alcohol and Isobutanol detection in mulberry wine was established.The result was compared with spectrophotometric method. 建立了利用氣質(zhì)聯(lián)用設(shè)備同時檢測桑果酒中異戊醇和異丁醇含量的方法,并與傳統(tǒng)的對二甲氨基苯甲醛比色法檢測結(jié)果進行了比較。

A new esterification equipment with a water separator by azeotropic rectification was used to the synthetic reaction of isopentyl acetate. 而且分水器排出廢水所帶出的酸僅為傳統(tǒng)裝置的25%25。

The yield of the ester could reach 99 % under amount of substance ratio of lactic acid, isopentyl alcohol and ferric chloride were 1:2 = 0.027, refluxing and water segrating for 60min. 當乳酸、異戊醇和三氯化鐵的物質(zhì)量比為1:2:0.
