description A compsn. comprises (a) 9-27 wt.% n-propoxypropanol (I); and (b) 73-91 wt.% octamethyltrisiloxane (II), where the compsn. is homogeneous and azeotropic at 0-148[deg]C and where the compsn. has a vapour pressure of 1000 Torr at 148[deg]C when the compsn. consists of 73 wt.% (II) and 27 wt.% (I), and of 0.8 Torr at 0[deg]C when the compsn. consists of 91 wt.% (II) and 9 wt.% (I). Also claimed is a compsn. comprising 9-46 wt.% (I) and 54-91 wt.% (II) which is homogeneous and azeotrope-like at 138.63-139.64[deg]C at 760 Torr.
