Versuchsvorschrift

10 g of p-amino benzoic acid were dissolved in 65 g of an 8.5% aqueous solution of hydrochloric acid. To this solution, 25 g of powdery menadione sodium bisulfite was added. After this addition, the solution was cooled to 5° C.; a white precipitate was obtained, which, after filtering, washing and vacuum drying, weighed 24 g.
