    摘要： The invention relates to a novel azeotropic or azeotrope-like mixture which essentially comprises about 90-97% by mass of 2,2,2-trifluoroethyl 1,1,2,2-tetrafluoroethyl ether and about 3-10% by mass of ethanol and also to a process for cleaning electrical or electronic components, in particular soldered circuit boards or printed circuits, but also other solid surfaces, with the aid of said mixture. Soldering fluxes, in particular, can be removed from circuit boards with the aid of said mixture.
