| titleOfInvention | Process for preparing trialkyl compounds of group IIIA metals |
| abstract | The invention relates to a method for preparing a compound of general formula R 3 M (wherein M ═ a metal of group IIIA of the Periodic Table of Elements (PTE), preferably gallium or indium, and R ═ C 1 ‑C 5 Alkyl, preferably methyl or ethyl) trialkyl metal compounds. The process is based on metal trichloride (MeCl) in the presence of at least one alkali metal halide as auxiliary base 3 ) With alkylaluminium sesquichloride (R) 3 Al 2 Cl 3 ) The reaction of (1). The reaction mixture is heated to a temperature above 120 ℃ and the trialkylmetal compound is separated from the reaction mixture via a separator, wherein the partially alkylated product is simultaneously recycled to the reaction mixture. In a further step, the reaction mixture is heated to a maximum of 350 ℃ and the remaining alkylated and partially alkylated products are separated off. The products obtained in this way can optionally be recycled into the process. The process exhibits high yields of trialkyl metal compounds and also a high metal utilization; these products are used as precursors for MOCVD processes. |
