丁二酮空气氧化工艺的产业化研究

Study on Industrialization of Diacetyl Produced by Air Oxidation Process

对丁二酮空气氧化工艺的产业化进行研究。在试验数据基础上,自行设计了生产中的关键设备——汽化器和氧化炉。以1 t乙偶姻发酵液的氧化生产进行考察,采用所设计的生产设备,平均氧化率达到73.6%,达到了预期的水平。

The industrialization of new air oxidation process for diacetyl was studied in this paper. The key equipments used in air oxidation process,such as vaporizer and oxidizing furnace,were designed upon the experimental data. The oxidation production of 1 t acetoin fermentation liquor was investigated by using this new process,the mean oxidation ratio reached to about 73. 6% with designed equipments,the result was at the same level as that in the previous laboratory experiment.
