The paper of Bingham and Fornwalt showed the need for fluidities of additional pure associated liquids. This paper is intended to supply that need particularly in the group of esters. The substances employed were obtained from the Eastman Kodak Company, but before use they were dehydrated with calcium chloride and distilled, the middle fraction being measured. Viscometer 1–23 and pyenometer 1–29 were used. The data on the fluidities and specific volumes are given in Tables I to XVII. The fluidity curves are nearly linear, and from the curves were read the temperatures required to give a certain desired fluidity, as, for example, 200 rhes. The atomic temperatures of Bingham and Spooner were used to calculate these temperatures, and the ratio of these two values gave the association n. These values are given in Table XVIII.
