Abstract
Novel azeotrope compositions comprised of a mixture of a fluorocyclopentane with a solvent selected from the group consisting of 1-bromopropane, t-dichloroethylene, and methylene chloride. Such compositions are useful as solvents in refrigeration flushing, oxygen system cleaning, foam blowing, and cleaning operations such as cold cleaning, vapor degreasing, and aerosol cleaners.
Claims26
An azeotrope composition comprised of:
- a first component comprised of at least one compound selected from the fluorocyclopentanes wherein a fluorine atom is substituted for from 3 to 9 hydrogen atoms;
- and a second component comprised of 1-bromopropane, wherein the amounts of each component are selected so that the final composition is an azeotrope.
A method for cleaning an organic contaminant from the surface of a solid substrate, which method comprises contacting said solid substrate at effective conditions with an effective amount of a solvent mixture comprised of a first component comprised of at least one compound selected from the fluorocyclopentanes wherein a fluorine atom is substituted for from 3 to 9 hydrogen atoms;
- and a second component comprised of 1-bromopropane wherein the amounts of each component are selected so that the final composition is an azeotrope.
