The p-acetamidobenzenesulphonyl chloride (Section IX,9) must be pure under no circumstances should it contain more than 1-2 per cont. of the corresponding sulphonic acid. This may be ensured by lixiviating the sulphonyl chloride with pure anhydrous acetone and filtering the solution from the acid. 

A solution containing 22 grams of y>aminophenylarsenoxidc and 18 15 grams of arsenic trichloride in 100 c.c. of methyl alcohol is slowly added to a well-coolestannous chloride in 200 c.c. of hydrochloric acid (density 1 19) and 200 c.c. of methyl alcohol. The product is brownish-yellow and cont ns 45 per cent, of arsenic. It is soluble in hot dilute hydrochloric acid and in moist pyridine, the acid solution yielding precipitates with dilute sulphuric acid and excess of sodium hydroxide.
