The synthesis of Isoamyl acetate with ethanoic acid and isoamylol as reactants and solid super acid Fe 2O 3-SO 4~ 2- as catalysts has such advantages as high catalizing efficiency,covenient and economical post-treatment,simple reaction technology,and non-corrosion to the equipment. 以固体超...
These impurities limit the production and recovery of ethanol from such reaction mixtures. For example, during hydrogenation, esters are produced that together with ethanol and/or water form azeotropes, which are difficult to separate. In addition when conversion is incomplete, unreacted acetic acid ...
Previous study has shown that enhanced IAA (indole-3-acetic acid) content enhanced the thermotolerance of the heat-sensitive strain YS3357. In this study, it was documented that IAA amendments could partly restore the resistance to T. atroviride and thermotolerance of the two LeDnaJ RNAi ...
In case an acid is employed as the condensation agent, the reaction is suitably conducted in an excess of this acid, without the addition of further solvent, at temperatures of between 0° and 100°C., preferably between 50° and 60°C. However, it is also possible to add a diluent, ...

The liquid-phase esterification of acetic acid and isoamyl alcohol has been studied to develop a kinetic model using a sequential experimental design based on the divergence criterion. Data come from batch reactor experiments, performed in the temperature range of 316–363 K. Discrimination among 36...
To provide a brewing yeast in which the brewing characteristics have been desirably modified by inhibiting gene function.SOLUTION: A method of producing a brewing yeast with high isoamyl acetate productivity, acetic acid productivity of low productivity, and high isoamyl alcohol productivity includes a...
