| titleOfInvention | Method for preparing trialkyl compound of group IIIA metal |
| abstract | The present invention relates to a process for preparing a metal having the formula R3M (wherein M = Periodic Table of the Elements (PTE) Group IIIA, preferably gallium or indium, and R = C1-C5 alkyl, preferably methyl or ethyl A method of a trialkyl metal compound. The process is based on the reaction of metal trichloride (MeCl3) with an alkyl aluminum sesquichloride (R3Al2Cl3) in the presence of at least one alkali metal halide as an auxiliary base. The reaction mixture is heated to a temperature above 120 ° C and the trialkyl metal compound is separated from the reaction mixture via a separator wherein a portion of the alkylated product is simultaneously recycled to the reaction mixture. In a further step, the reaction mixture is heated to a maximum of 350 ° C and the remaining alkylated and partially alkylated product is isolated. The products obtained in this manner can optionally be recycled into the process. This process shows high yields of trialkyl metal compounds and also a high metal utilization; these products are used as precursors for MOCVD processes. |
