Trimethylaluminium Specification

The IUPAC name of this chemical is Trimethylaluminum. With the CAS registry number 75-24-1 and EINECS registry number 200-853-0, it is also named as Aluminum, trimethyl-. In addition, the molecular formula is C₃H₉Al and the molecular weight is 72.09. It is a kind of clear colorless solution and belongs to the classes of Organometallics; Al (Alminum) Compounds; Alkyl Metals; Classes of Metal Compounds; Grignard Reagents & Alkyl Metals; Synthetic Organic Chemistry; Typical Metal Compounds; Chemical Synthesis; Organoaluminum; Organometallic Reagents.

Preparation and uses of Trimethylaluminum: it can be prepared by dimethylmercury and aluminium with heating. Also it can be prepared by trihalidetrimethyldialuminium and aluminium. And it is mainly used for the production of methylaluminoxane, an activator for Ziegler-Natta catalysts for olefin polymerisation. In addition, it is used as the raw materials for MOCVD process and used in semiconductor fabrication to grow thin film. And it can react with 3-methyl-cyclohex-2-enone to get 3,3-dimethyl-cyclohexanone. This reaction will need reagents CuBr and Me₃SiCl and solvent tetrahydrofuran. The reaction time is 1 hour at reaction temperature of 0 °C. The yield is about 97%.

Trimethylaluminum can react with 3-methyl-cyclohex-2-enone to get 3,3-dimethyl-cyclohexanone

When you are using this chemical, please be cautious about it as the following:
It is highly flammable and spontaneously flammable in air. And it can cause burns and react violently with water, liberating extremely flammable gases. In addition, it is very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. It may cause lung damage if swallowed. Besides, it may risk of impaired fertility and is harmful to the unborn child. During using it, wear suitable protective clothing, gloves and eye/face protection and avoid contact with skin and eyes. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. And in case of accident or if you feel unwell, seek medical advice immediately (show label where possible). If swallowed, do not induce vomiting: seek medical advice immediately and show this container or label. Moreover, keep away from sources of ignition-No smoking. This material and its container must be disposed of as hazardous waste. Take precautionary measures against static discharges. In case of fire, use ... (indicate in the space the precise type of fire-fighting equipment. If water increases the risk).
