The results of analysis of available information sources of K group vitamins production, which include 2-methyl-1, 4-naphtoquinone (menadione), menadione sodium bisulfite (MSB), menadionenicotinamide bisulfite (MNB) are presented. The main problem of the advanced method of a production, based on using of hexavalent chrome for producing mena-dione as an intermediate compound in the technology is high concentration of chrome in the final product. It is shown that providing of high technical and economical indexes in industrial vitamin production requires researching the chrome displacement at the technological process key stages special aspects and the validation of the target compound effective clearing modes. The statement-type character of the article is aimed to simplify the next publications in this research topic.
