The glyoxal product turns yellow upon production; its alcohol content is 2.6, and its specific gravity is around 270. I would appreciate it if experts could analyze the reasons for this
1. The alcohol content is high; the acid content is likely to be high as well. The reaction does not proceed well, and when the levels of acid, alcohol, formaldehyde, etc. are high, it is difficult to control the color of the product； 2. The high colority of the crude product is caused by factors such as excessive temperature control in one of the towers.
