| titleOfInvention | Process for preparing trialkyl compounds of metals of group iiia |
| abstract | The present invention relates to a process for the preparation of a compound of the formula I R 3 M wherein M = a group IIIA metal of the Periodic Table of the Elements (PTE), preferably gallium or indium, and R = C 1 -C 5 -alkyl, preferably methyl or ethyl And a method for producing an alkyl metal compound. The process is based on the reaction of a metal trichloride (MeCl 3 ) with an alkyl aluminum sesquichloride (R 3 Al 2 Cl 3 ) in the presence of at least one alkyll metal halide as an auxiliary base. The trialkyl metal compound is separated from the reaction mixture through a separator, while the reaction mixture is heated to a temperature above 120 ° C and the partial alkylation product is recycled to the reaction mixture at the same time. In a further step, the reaction mixture is heated to a maximum of 350 < 0 > C and the remaining alkylated and partially alkylated products are separated. The product obtained in this way can optionally be recycled to the process. The method shows a high yield of trialkyl metal compound and also a high metal utilization; The product is used as a precursor for the MOCVD process. |
