Homogeneous nucleation in associated vapors. III. Heptanoic, decanoic, and myristic acids

Abstract

Homogeneous nucleation measurements have been made on heptanoic, decanoic, and myristic acid vapors, all of which exhibit small degrees of hydrogen bond association. The measured temperature dependences of the critical supersaturation are compared with predictions of the Katz–Saltsburg–Reiss theory for nucleation in associated vapors as well as the conventional Becker–Döring–Zeldovitch theory. Heptanoic acid and decanoic acid show good agreement with theory while the myristic acid critical supersaturation measurements are consistently low
