Additional information

Information concerning melting/freezing point of MIBK was sourced from three separate handbooks. 

Merck Index: An Encyclopedia of Chemicals, Drugs, and Biologicals (14th Ed.), CRC Handbook of Chemistry and Physics (81st Ed.)which are known to contain peer-reviewed data of Klimisch-2 reliability and the Directory of Solvents, Blackie Academic & Professional, 1996, not assignable.

The three handbooks state that the substance has a melting point circa -84°C (corresponding to 189.15 K).
