Phenylbromethylbenzenesulfonamid and phenylbromethylamin by Carl Leopold von Ende, 1893

Phenylbromethylbenzenesulfonamide and Phenylbromethylamin by Carl Leopold von Ende, 1893, Page 20

allowed to run into a mortar and is worked up several times with alcohol and finally with a twice molecular NaOH solution, after this it is filtered off and washed with water.

The residue is a white mealy mass from which the phenylbromethylbenzensulfonamid is extracted, in an extractor, by means of gasoline with distills over under 80 degrees. It readily crystallizes out from the gasoline in beautiful, fine, colorless needles.

From the NaOH washings the dissolved and unchanged benzensulfanilid, can be recovered by precipitating with an acid. The alcohol is distilled off from the alcohol washings; the residue is worked up again, in a similar way, with a small amount of alcohol and then NaOH and lastly is extracted with gasoline the same as the other.

The product thus obtained melts at 88 degrees.
