Useful:

• Uses: Trimethylaluminium can be used as catalyst for olefin polymerization, pyrophoric fuel, manufacture of straight-chain primary alcohols and olefins, to produce luminous trails in upper atmosphere to track rockets. Trimethyl aluminum is a highly reactivereducing and alkylating agent. It is used in aZiegler-Natta catalyst for polymerization andhydrogenation. Trimethylaluminum can be used in the pretreatment of Al2O3/p-type GaSb capacitors.

Technology Process of Trimethylaluminium

There total 71 articles about Trimethylaluminium which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 96.8%

gallium (7440-55-3) + methyl aluminium sesquichloride → trimethylaluminum (75-24-1) + trimethyl gallium (1445-79-0)

Guidance literature:

With methylene chloride; sodium; at 40 - 50 ℃; under 375.038 Torr; Inert atmosphere; Flow reactor;

Reference yield: 87.0%

methylene chloride (74-87-3) + dimethylaluminum chloride (1184-58-3) → trimethylaluminum (75-24-1)

Guidance literature:

With sodium; copper; In Hexadecane; at 20 - 130 ℃; for 2.2h; under 825.083 - 862.586 Torr; Inert atmosphere; Flow reactor;
