Iodomethane Specification
The Iodomethane, also known as Iodure de methyle, is the chemical compound with the formula CH3I. It belongs to the product categories of Organics; Piperazine Derivates. Its EINECS registry number is 200-819-5. With the CAS registry number 74-88-4, its IUPAC name is iodomethane. Iodomethane is used in organic synthesis as a source of methyl groups, and was approved for use as a pesticide in a controversial decision by the United States Environmental Protection Agency in 2007. It can be used for the methylation of carboxylic acids or phenols. Iodomethane has also been proposed for use as a fungicide, herbicide, insecticide, nematicide, and as a soil disinfectant, replacing bromomethane (banned under the Montreal Protocol).
Physical properties of Iodomethane: (1)ACD/LogP: 1.61; (2)ACD/LogD (pH 5.5): 1.609; (3)ACD/LogD (pH 7.4): 1.609; (4)ACD/BCF (pH 5.5): 9.841; (5)ACD/BCF (pH 7.4): 9.841; (6)ACD/KOC (pH 5.5): 178.832; (7)ACD/KOC (pH 7.4): 178.832; (8)Index of Refraction: 1.528; (9)Molar Refractivity: 19.651 cm3; (10)Molar Volume: 63.868 cm3; (11)Surface Tension: 27.25 dyne/cm; (12)Density: 2.222 g/cm3; (13)Flash Point: 7.798 °C; (14)Enthalpy of Vaporization: 27.298 kJ/mol; (15)Boiling Point: 40.313 °C at 760 mmHg; (16)Vapour Pressure: 437.086 mmHg at 25°C.
Preparation: Iodomethane is formed via the exothermic reaction that occurs when iodine is added to a mixture of methanol with red phosphorus. The iodinating reagent is phosphorus triiodide that is formed in situ:
3 CH3OH + PI3 → 3 CH3I + H3PO3
Uses of Iodomethane: it can be used for the methylation of carboxylic acids or phenols:
When you are using this chemical, please be cautious about it as the following:
