DOT Classification:  3; Label: Flammable Liquid

5-Methyl-2-hexanone Specification

The IUPAC name of Methyl isoamyl ketone is 5-methylhexan-2-one. With the CAS registry number 110-12-3 and EINECS 203-737-8, it is also named as 2-Hexanone, 5-methyl-. The classification codes are Agricultural Chemical; Skin / Eye Irritant; TSCA Flag T [Subject to the Section 4 test rule under TSCA]; Unspecified / Unclassified pesticide. It is clear colourless liquid with a pleasant fruity odor. When heated to decomposition it emits acrid smoke and irritating fumes. So the storage environment should be well-ventilated, low-temperature and dry. Keep Methyl isoamyl ketone separate from oxidant.

The other characteristics of this product can be summarized as: (1)ACD/LogP: 1.78; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.78; (4)ACD/LogD (pH 7.4): 1.78; (5)ACD/BCF (pH 5.5): 13.36; (6)ACD/BCF (pH 7.4): 13.36; (7)ACD/KOC (pH 5.5): 222.62; (8)ACD/KOC (pH 7.4): 222.62; (9)#H bond acceptors: 1; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 3; (12)Polar Surface Area: 17.07 Å2; (13)Index of Refraction: 1.401; (14)Molar Refractivity: 34.46 cm3; (15)Molar Volume: 141.5 cm3; (16)Polarizability: 13.66×10-24 cm3; (17)Surface Tension: 23.9 dyne/cm; (18)Density: 0.806 g/cm3; (19)Flash Point: 41.1 °C; (20)Enthalpy of Vaporization: 38.11 kJ/mol; (21)Boiling Point: 144 °C at 760 mmHg; (22)Vapour Pressure: 5.2 mmHg at 25°C.

Preparation of Methyl isoamyl ketone: It can be obtained by 5-methyl-2-(trimethylsiloxy)-1-hexene. This reaction needs reagent tributyltin fluoride, catalytic agent PdCl2(P(o-MeC6H4)3)2 and solvent benzene by heating. The reaction time is 30 min. The yield is 96%.

Methyl isoamyl ketone can be obtained by 5-methyl-2-(trimethylsiloxy)-1-hexene

Uses of Methyl isoamyl ketone: It is used in organic synthesis. For example: it can react with 4-methoxy-benzaldehyde to get 1-(4-methoxy-phenyl)-6-methyl-hept-1-en-3-one. This reaction needs catalytic agent Ba(OH)2 C-200 and solvent ethanol by heating. The reaction time is 1 hours. The yield is 89%.
