WebMar 5, 2024 · Measurement of a solid compound's melting point is a standard practice in the organic chemistry laboratory. The melting point is the temperature where the solid-liquid phase change occurs. In some reference books it is listed as a single value (e.g. 98˚C), but in chemical catalogs it is more often listed as a range of values (e.g. 96-98˚C). WebThe melting point of ferrocene: 173-174 °C and the melting point of acetylferrocene is 81-83 °C. The melting point of adipic acid is 151-154 °C and the melting point of citric acid 153-155 °C. Adipic acid and citric acid have very similar melting points.
