Surface tension study of concentration dependent cluster breaking in acetone-alcohol systems


Alcohols are well-known for the formation of clusters due to hydrogen bonds. When a second molecular species such as acetone is added to an alcohol system, the hydrogen bonds are broken leading to a destruction of the molecular clusters. In this paper we report the findings of surface tension study over the entire concentration region of acetone and six alcohol systems over the entire concentration range. The alcohols chosen were methanol, ethanol, isopropanol, butanol, hexanol and octanol. Surface tension was measured using the pendent drop method. Our study showed a specific molecular interaction near the 1:1 concentration of lower alcohols and acetone whereas the higher alcohols did not exhibit the same.
