Abstract
Non-inflammable solutions, plastics, lacquers, &c. are produced by dissolving a degraded cellulose nitrate of low viscosity (obtained by boiling primary cellulose nitrate with water or dilute acids) in a solvent mixture containing carbon tetrachloride in amount at least twice that of the actual solvent present. Known solvents such as ethyl acetate, acetone, or amyl acetate may be employed with the carbon tetrachloride, together if desired, with the customary plasticizers. Spraying lacquers, made up with cellulose nitrate of the above mentioned type, may be diluted with carbon tetrachloride to give a non-inflammable product. The Specification as open to inspection under Sect. 91 relates also to the use of carbon tetrachloride in admixture with other halogenated hydrocarbons, for example, methylene chloride or ethylene chloride. This subject-matter does not appear in the Specification as accepted.ALSO:Non-inflammable solutions, plastics, lacquers, &c., are produced by dissolving a degraded cellulose nitrate of low viscosity (obtained by boiling primary cellulose nitrate with water or dilute acids) in a solvent mixture containing carbon tetrachloride in amount at least twice that of the actual solvent present.
