Title:
HIGH-PURITY TRIALKYLGALLIUM AND ITS PREPARATION METHOD
Document Type and Number:
Japanese Patent JP2008081451
Kind Code:
A
Abstract:
To provide a high-purity trialkylgallium through a simple method, and the method thereof.
Trialkylgallium (wherein the alkyl group contains 1-6 carbons) is reacted with a trialkylamine to form a complex, the complex is purified through distillation, and the trialkylamine is dissociated to recover the free trialkylgallium. This yields the high-purity trialkylgallium having a silicon atom content of 0.1 mass ppm.
