摘要：Azeotropes seem to have beco me something of a hot to pic of late. There was considerable discussion about them at the recent AIC Varnish Workshop held at the Getty Museum. I've been trying to make sense of them in the contex t of the Modular Cleaning Program (MCP) an d so lu bility theory. In fact, a few years ago, I read that a new commercial p aint stripper used a "patented azeotrope" formu lation. So, what is an azeotrope. Basically it is a mixture of solvents behaving badly. Well, not ex actly badly, but unexpectedly. Understanding azeotropes, or at least being aware of their presence, can allow a better un derstanding of how certain solvent mixtures change as th ey ev aporate. The definition of an azeotrope (from American Heritag e Dictionary) is: "A liquid mixture of two or more substances th at retains the same comp osition in the vapor state as in the liqu id state when distilled or partially evaporated under a certain pressure."
