Abstract: Cryoscopic constants (Kf) were experimentally determined using a differential thermal analyzer (DTA) for a series of four tetra-n-alkylammonium bromides. Compatibility tests between this series of salts and various structural components of the testing apparatus were performed. (n-c5h11)4Br was found to have a value of 12.2 °C/m, and (n-C7H13)4Br was found to have a valur of 31.7 °c/M. Irreproducible results prevented the determination of Kf for (n-C6H13)4Br of salt (N-C4H9)4Br. It was found that none of the elements of the experimental apparatus reacted with the salts. The materials tested were Teflon, Viton, Pb and CaF2.
