- Executive summary:
The freezing point of tetrabutyltin was determined using BS4633: Method for the Determination of Crystallizing Point, Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The freezing point is less than 253 ± 0.5 K (< -20 °C).
Reference
The determination was carried out in duplicate.
Graphs of temperature (K) versus time (seconds) were constructed to obtain the freezing temperature (attached figures).
