Melting temperatures, along with transition temperatures when they occur, are summarized for 70 pure chemicals used as the components in the study of 112 binary (solid + liquid) phase diagrams reported by us over the past 35 years. The melting temperatures and compositions of 68 solid molecular addition compounds determined as a part of these studies are also reported, and the proposed molecular interactions leading to the formation of these addition compounds are reviewed and discussed. Temperatures were measured with strain-free platinum resistance thermometers (Leeds and Northrup or Rosemount) that were calibrated to conform with the ITS-48 or the IPTS-68 temperature scales. The temperature scale used is estimated to be accurate to +/- 0.02 K over the temperature range of the measurements. Equations are given to convert temperature from ITS-48 or IPTS-68 to the more recent ITS-90 scale, and used to convert the temperatures reported in the tables to ITS-90.
