WebTools. In thermodynamics, superheating (sometimes referred to as boiling retardation, or boiling delay) is the phenomenon in which a liquid is heated to a temperature higher than its boiling point, without boiling. This is a so-called metastable state or metastate, where boiling might occur at any time, induced by external or internal effects. WebThat is 50% methyl acetate and 50% propyl acetate. If you don't know what methyl acetate or propyl acetate are not a big deal, but what's interesting is the difference in their boiling points.
