Abstract:
Mixtures comprising water, tertiary amyl alcohol and tetrachlorodifluoroethane which, over substantially the entire course of their evaporation or distillation, form azeotropic nonflammable vapors containing tertiary amyl alcohol and tetrachlorodifluoroethane. These mixtures are useful in dry cleaning textile fabrics and fibers with reduced hazard of fire.
Abstract:
TETRACHLORODIFLUOROETHANE (SYM.-, ASYM.-, AND MIXTURES THEREOF) NITROMETHANE, WATER AND ISOPROPANOL OR SECONDARY BUTANOL FORM QUATERNARY AZEOTROPIC MIXTURES WHICH ARE USEFUL AS DRY CLEANING SOLVENTS AND ARE PARTICULARLY USEFUL FOR THE REMOVAL OF HARD-TO-REMOVE STAINS FROM LEATHER.
Abstract:
TETRACHLORODIFLUOROETHANE (SYM-, ASYM-, AND MIXTURES THEREOF), SECONDARY BUTANOL AND NITROMETHANE FORM TERNARY AZEOTROPIC MIXTURES WHICH ARE CONSTANT BOILING. THESE AZEOTROPES ARE USEFUL AS SOLVENTS FOR CLEANING PRINTED CIRCUIT BOARDS AND THE LIKE.
Abstract:
Cross-linked low chlorine- and sulfur-content sulfochlorinated polyethylene has superior properties over both cross-linked polyethylene and cross-linked high chlorine- and sulfur-content sulfochlorinated polyethylene. In addition, it possesses processing advantages over polyethylene and highly chlorosulfonated polyethylene.
