Specification

The systematic name of this chemical is trimethylphosphane. With the CAS registry number 594-09-2, it is also named as phosphine, trimethyl-. The product's categories are Catalysis and Inorganic Chemistry; Phosphine Ligands; Phosphorus Compounds. It is colorless liquid with a strongly unpleasant odour, which is sensitive to air and moisture. What's more, this chemical is highly flammable, so people should keep it away from sources of ignition. When heated to decomposition it emits toxic fumes of PO_x. Additionally, it also be kept in a well-ventilated place.

The other characteristics of this product can be summarized as: (1)ACD/LogP: 0.82; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 0.82; (4)ACD/LogD (pH 7.4): 0.82; (5)ACD/BCF (pH 5.5): 2.46; (6)ACD/BCF (pH 7.4): 2.46; (7)ACD/KOC (pH 5.5): 66.35; (8)ACD/KOC (pH 7.4): 66.35; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 13.59 Å²; (13)Enthalpy of Vaporization: 27.32 kJ/mol; (14)Boiling Point: 40.5 °C at 760 mmHg; (15)Vapour Pressure: 434 mmHg at 25°C.

Preparation of Trimethylphosphine: It can be obtained by using Grignard reagents: 3 CH₃MgBr + P(OC₆H₅)₃ → P(CH₃)₃ + 3 MgBrOC₆H₅. The synthesis is conducted in dibutyl ether, from which the more volatile PMe₃ can be distilled.

Uses of Trimethylphosphine: It is used in the preparation of organic phosphorus compounds and frequently-used phosphine ligand. It is also a highly basic ligand that forms complexes with most metals. In addition, it can react with bromomethyl-benzene to get benzyl-trimethyl-phosphonium; bromide. This reaction needs solvent ethanol. The reaction time is 2 days. The yield is 93%.

When you are using this chemical, please be cautious about it as the following:
It is not only irritating to eyes, respiratory system and skin, but also may cause lung damage if swallowed. It also has danger of serious damage to health by prolonged exposure. Vapours may cause drowsiness and dizziness. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Take precautionary measures against static discharges. If you want to contact this product, you must wear suitable protective clothing, gloves and eye/face protection. If swallowed, do not induce vomitting; seek medical advice immediately and show this container or label.
