Hydrochloric Acid → HCID 13151013, compound

Participants

Reaction Steps

The hydroiodide obtained as described above is suspended in distilled water (70 cc). Sodium bicarbonate (2.93 g) is added to this suspension: this gives a solution of pH 7, containing a very small amount of insoluble material, which is filtered off. The filtrate obtained is then acidified to pH 5 by adding a 1 N aqueous solution of hydrochloric acid (16.5 cc). The product which precipitates is filtered off and then washed with water (9×10 cc). After drying, (3-phenylimino-1,2-dithiol-5-ylthio)-acetic acid (3.7 g), melting at 147° C., is obtained.
