Title compds., useful as vulcanization accelerators, was prepd. by the reaction of morpholine with 1,2-benzothiazolyl disulfite, mercaptobenzothiazole and their sodium salt in the presence of oxidizing agent. Thus,27.5 kg 2,6-dimethylmorpholide was prepd. from 138 kg compd. of 20 % 2-benzothiazolylsulfenic acid-2,6-dimethylmorpholide, 20 % 2,6-dimethylmorpholine, 7.5 % NaCl, 51 % H2O and 1.5 % by-product. The product was cooled by the scraping roller to give title compd.
