This paper describes observations, mostly made in 1924 and not hitherto published in detail,* on the surface pressure of γ hydroxy-stearic acid (I) and its lactone (II) spread as monomolecular films on aqueous solutions. CH3 3 CH3 3 (CH 2 ) 13 (CH 2 ) 13 CHOH CH CH 2 CH 2 CH 2 O COOH CH 2 – CO I II Most of the measurements were made with the modification of Langmuir’s apparatus described in Parts I and II of this series of papers,† in which jets of air prevent the film passing the ends of the float. A few confirmatory observations have been made since, with the apparatus of Adam and Jessop, in which thin metallic ribbons block these gaps. The acid and lactone were kindly given me by Dr. P. W. Clutterbuck, of Manchester University.

The synthesis of 1,3-diundecanoyloxyacetone (1) and 1-undecanoyloxy-3-hydroxyacetone (2) is reported. The properties of 1, spread as a pure monomolecular film and in mixed films with stearic acid, were determined and evaluated. Compound 2 did not form films. The compounds were designed to exert, potentially, long-lasting insect-repellent activity subsequent to anchoring to the skin.
