Additional information

Information regarding vapour pressure of MIBK was sourced from CRC Handbook of Chemistry and Physics (81st Ed.) and The Condensed Chemical Dictionary (10th Ed.), known to contain peer-reviewed data of Klimisch-2 reliability and the Directory of Solvents, Blackie Academic & Professional, 1996, not assignable

Based on the information obtained from the aforementioned sources the vapour pressure of MIBK was reported as 2.64 kPa at 25°C (2640 Pa at 298.15 K) and 15.7 mmHg at 20°C (2093 Pa at 293.15 K) and 2.5 kPa at 25°C.
