Abstract
Disclosed is a cleaning composition of about 80 to about 99 wt % benzotrifluoride, about 1 to about 20 wt % monohydric alkanol from C.sub.1 to C.sub.4, and up to about 20 wt % of a fluorocarbon having the general formula C.sub.m H.sub.n F.sub.2m+2n, where m is 4 to 8 and n is 1 to m/2 if m is even and (m+1)/2 if m is odd. The composition is useful in cleaning greases, oils, solder fluxes, and other soils.

A composition comprising about 80 to about 99 wt % benzotrifluoride, about 1 to about 20 wt % of a monohydric alkanol from C.sub.1 to C.sub.4, and about 1 to about 20 wt % of a fluorocarbon having the general formula C.sub.m H.sub.n F.sub.2m+2-n, where m is 4 to 8 and n is 1 to m/2 if m is even or (m+1)/2 if m is odd, and said composition is suitable for use as a cleaning composition.
A composition consisting essentially of about 80 to about 99 wt % benzotrifluoride, about 1 to about 20 wt % of a monohydric alkanol from C.sub.1 to C.sub.4, and up to about 20 wt % of a fluorocarbon having the general formula C.sub.m H.sub.n F.sub.2m+2-n, where m is 4 to 8 and n is 1 to m/2 if m is even and (m+l)/2 is m is odd and said composition is suitable for use as a cleaning composition.
A composition comprising about 85 to about 95 wt % benzotrifluoride, about 5 to about 15 wt % monohydric alkanol, and about 1 to about 15 wt % of a fluorocarbon having the general formula C.sub.m H.sub.n F.sub.2m+2, where m is 4 to 8 and n is 1 to m/2 if m is even and (m+1)/2 if m is odd and said composition is suitable for use as a cleaning composition.
