2-甲基丙酸乙酯制备

1.由异丁酸和无水乙醇酯化而得。将异丁酸和无水乙醇混匀后，小心加入浓硫酸，加热回流14h后，依次用水、饱和碳酸氢钠溶液、水洗涤，经无水硫酸镁干燥后，进行蒸馏，收集109-111℃馏分，得2-甲基丙酸乙酯，收率69%。

2.由异丁酸与乙醇在共沸条件下加热酯化后蒸馏而得。

Combined effects of nutrients and temperature on the production of fermentative aromas by Saccharomyces cerevisiae during wine fermentation.

Appl. Microbiol. Biotechnol. 99(5) , 2291-304, (2015)

Volatile compounds produced by yeast during fermentation greatly influence the organoleptic qualities of wine. We developed a model to predict the combined effects of initial nitrogen and phytosterol ...

Olfactometry Profiles and Quantitation of Volatile Sulfur Compounds of Swiss Tilsit Cheeses.

J. Agric. Food Chem. 63 , 7511-21, (2015)

To establish the odor profiles of three differently fabricated commercial Swiss Tilsit cheeses, analyses were conducted using headspace solid-phase microextraction gas chromatography-mass spectrometry...

How do esters and dimethyl sulphide concentrations affect fruity aroma perception of red wine? Demonstration by dynamic sensory profile evaluation.

Food Chem. 194 , 196-200, (2015)

Our study focused on variations in wine aroma perception and molecular composition during tasting over a period of 30min. In parallel, dynamic analytical and sensory methods were applied to study chan...
