  • Patent number: 3939210
    Abstract: Mercaptophenols are selectively oxyalkylated at the mercapto function by a two-step process comprising reacting the mercaptophenol with a silylating agent to form novel silylated mercaptophenol derivatives and thereafter oxyalkylating the phenolic mercapto function to the degree of oxyalkylation desired. Simple hydrolyzing of the resulting product breaks the silylation block forming a hydrolyzed oxyalkylated mercaptophenol.

  • Patent number: 3933988
    Abstract: A process for the production of chlorine dioxide and a sulfate salt comprising mixing an aqueous solution of a chlorate, sulfuric acid and sulfur dioxide, reacting said mixture under reduced pressure near the boiling point of said solution at a temperature of 50.degree. to about 95.degree. centigrade to generate chlorine dioxide, removing water from the chlorate solution as water vapor with the generated chlorine dioxide, feeding replenishing amounts of aqueous chlorate to said reaction mixture to increase the concentration of the cation of said chlorate so as to have it exceed the saturation point of the sulfate of said cation under said reaction conditions, crystallizing a sulfate salt of said cation from said reaction mixture and recovering said sulfate salt.
