Abstract: New compounds are disclosed of the formula: ##EQU1## wherein R is selected from the group consisting of lower alkyl of 1-6 carbon atoms, phenyl and alkyl substituted phenyl and R' is selected from the group consisting of phenyl, lower alkenyl and halogen substituted and unsubstituted lower alkyl of 1-6 carbon atoms. The compounds of this invention are useful as flame retarding agents for textile materials and in the production of polymers and copolymers which possess flame retardant properties.
Abstract: New compounds and a process for the preparation thereof are disclosed of the formula:R.sub.n ArCCl=CClHwherein Ar is an aromatic nucleus, aromatic being defined herein as a derivative of benzene, each R is independently selected from halogen, alkyl and haloalkyl and n is an integer from 2 to 4. The above compounds are useful as chemical intermediates for the preparation of compounds having herbicidal activity.

Abstract: Compounds of the formula: ##EQU1## wherein R' is selected from the group consisting of .sup.-OH, alkoxy and aryloxy; and R is selected from the group consisting of ##EQU2## wherein Z is .sup.-OH, alkyl, aryl, alkoxy and aryloxy, provided when R' is .sup.-OH, ##EQU3## are disclosed, having utility as metal ion sequestrants and flame retardant additives.
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.
Abstract: New flame retardant materials are disclosed having applied thereto compounds of the formula: ##SPC1##Wherein R is selected from the group consisting of phenyl, lower alkenyl and halogen substituted and unsubstituted lower alkyl of 1-6 carbon atoms, X is selected from the group consisting of chlorine, bromine and lower alkyl of 1-6 carbon atoms, m is an integer from 1-4 and n is an integer from 0-5, provided that the sum of m and n is not greater than 6 and when m is 1, n is greater than 0.
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.
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.
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.
