NIOSH REL: Ketones (Methyl Isoamyl Ketone) TWA 230 mg/m3
DOT Classification: 3; Label: Flammable Liquid
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%.
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%.
When you are using this chemical, please be cautious about it as the following:
It is not only flammable, but also harmful by inhalation. So people should not breathe vapour and avoid contact with skin and eyes.
People can use the following data to convert to the molecule structure.
1. SMILES:O=C(C)CCC(C)C
