    摘要: When certain weight ratios of certain flammable additive components (an ether and an epoxyalkane) are blended in n-propyl bromide, the components can actually function as flame retardants or flame suppressants when the resulting cleaning composition is used in aerosol applications. The proportions of the additives used are small; yet suitably effective stabilization against metallic corrosion is achieved even at mildly elevated temperatures.

    摘要: A process for removing contaminants from the surface of a substrate comprises contacting the substrate with a cleaning composition comprising at least one mono-, di-, or trialkoxy-substituted perfluoroalkane, perfluorocycloalkane, perfluorocycloalkyl-containing perfluoroalkane, or perfluorocycloalkylene-containing perfluoroalkane compound, the compound optionally containing additional catenary heteroatoms. The compounds exhibit good solvency properties while being environmentally acceptable.
