  • Patent number: 3933122
    Abstract: An apparatus for use in a process for imparting flame retardance to cellulose containing materials which comprises an enclosed chamber having means for introducing a treating gas into the chamber and maintaining the gas in a treatment chamber where it is in contact with a cellulosic textile material which has been introduced into the chamber and is passed therethrough. The chamber is readily adaptable to high speed commercial textile processing machinery.

  • Patent number: 3933987
    Abstract: A process for the production of chlorine dioxide, chlorine and an inorganic salt comprising reacting an aqueous solution of a chlorate with hydrochloric acid under reduced pressure at a temperature near the boiling point of said solution, withdrawing produced chlorine dioxide, chlorine and water vapor from said solution, replenishing said solution with an additional amount of chlorate and acid, saturating said solution with a cation of said chlorate and an anion of said acid and crystallizing in said solution, a salt of the cation of the chlorate and the anion of the said acid.

  • 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.
