Abstract
A novel minimum boiling binary azeotrope of n-undecane and n-butyl-3-hydroxybutyrate is shown to have utility as a solvent for degreasing of both nonpolar and polar contaminants. The components of the azeotrope are stable against degradation and the composition is largely invariant with pressure, yielding a unique solvent that can be used in cold cleaning and in vapor degreasing at elevated temperatures and over a wide range of pressures.
