WebMay 15, 2010 · Abstract. Spherical 2-diazo-4,6-dinitrophenol (DDNP) with good flowability and controlled bulk density (0.65-0.95 g/cm (3)) has been prepared at factory scale by the modified method using 4-methylphenol as crystal control ingredient. Results showed that the yield of product was increased by 5-10%, and the waste water was significantly … Diazodinitrophenol (DDNP) was the first diazo compound produced; it was subsequently used to make dyes and explosives. It forms yellow crystals in pure form; however, the color of impure forms may vary from dark yellow to green to dark brown. It is soluble in acetic acid, acetone, concentrated hydrochloric acid, most non-polar solvents and is slightly soluble in water.
