- Abstract:
-
The effects of raw material ratio, reaction temperature, reaction time and other factors on product yield were studied, and the optimal reaction conditions obtained were: the molar ratio of 2-methyl-1,4-naphthoquinone to sodium bisulfite was 1:1.5. The amount of water is 2.1 times the amount of 4-methyl-1,5-naphthoquinone; The amount of ethanol is 2.1 times the amount of 4-methyl-3,5-naphthoquinone; The reaction temperature is 55 °C; The reaction time was 1 h. Under optimal conditions, the yield of vitamin K3 was stable at more than 72.5% and the purity was stable at more than 94%. And the product was verified by infrared spectroscopy.
