Conclusions:
The Freezing point of Reaction mass of Methylium, tris[4-​(diethylamino)​phenyl]​-​ & acetate was determined with freezing temperature and it was found to be less than -8.6 °C at 975 hPa.
Executive summary:

The Freezing point determination of Reaction mass of Methylium, tris[4-​(diethylamino)​phenyl]​-​ & acetate was done using crushed ice and salt. No freezing was observed up to -8.6°C.

Hence, the freezing point was inferred to be less than -8.6 °C at 975 hPa.
