 EMI2.1
 Acid and potassium iodide are reduced to 4-0xy-3-methylaminobenzolarsinoxide, which is filtered off with suction and converted into the readily water-soluble sodium monoformaldehyde sulphoxylate in the usual way by the action of sodium formaldehyde sulphoxylate.



   31'3 g of this sulfoxylate are in aqueous solution with 33'3 g of 3-0xy-4- [bis- (3. Y-dioxypropyl) -
