The invention provides a device for removing ether from a trialkyl indium-ether complex. The feed is fed by setting a head tank, and the reaction tank is stirred and dissociated. The mixture of trialkyl indium is discharged through the discharge valve for rectification, and the nitrogen pipe is connected to the head tank and the condenser to protect the whole reaction; The diethyl ether is immediately separated from the mixed system, and the conventional trialkylindium-ether complex dissociation diethyl ether and diethyl ether separation are combined in the same device to realize two different processes; through this technical scheme, the same trialkylindium product can be obtained At the same time, the efficiency of ether removal is increased by 20%-40%; at the same time, because the dissociation and separation are combined in the same unit operation, the production efficiency is improved and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of high-purity trialkyl indium production, in particular to a device for removing ether from a trialkyl indium-ether complex. Background technique [0002] High-purity trimethylindium is the key raw material for the epitaxial growth of indium phosphide and other indium compound semiconductor optoelectronic materials by metal organic chemical vapor deposition (MOCVD). Conventional production of high-purity trialkylindium is mainly to prepare trialkylindium-ether complexes through Grignard reaction, and then add new ligands to form new ligands between trimethylindium and new ligands, and then Separate the dissociated ether. However, the existing technology cannot realize the instant separation of diethyl ether while dissociating diethyl ether, which increases equipment and labor costs for the large-scale production of trimethyl indium. Therefore, it is necessary to solve the above problems. Contents of the...
