A mixture of dodecyl phenol (1.0m., 262g.), sulphur (1.0m., 32g.) and caustic soda (8g.) was heated, with stirring, under nitrogen, at 160° C until the evolution of hydrogen sulphide ceased (42 hrs.). The caustic soda was neutralized with 10 ml. of phosphoric acid (SG = 1.75) and the mixture was then filtered. %S of Product = 5.85 (calc. = 5.8).
