Method for recycling organometallic compound for MOCVD

Abstract

The present invention is a method for recycling an organometallic compound for MOCVD comprising extracting an unreacted organometallic compound from a used raw material which has undergone a thin film production process, wherein the unreacted organometallic compound is extracted after the used raw material is subjected to a reforming treatment. The method for reforming the used raw material is either a method for contacting the used raw material with a hydrogenation catalyst or a reducing agent or a method for contacting the used raw material with either a halogen, a hydrogen halide, an inorganic acid, an alkene, or a diene. In this case, an organometallic compound of higher purity can be obtained through this recycling method by contacting the used raw material with a decoloring agent comprising activated carbon, silica, or activated clay.
