Abstract: According to the process of the present invention, trialkylarsenic compounds having a very high purity of usually over 99% can be obtained by using inexpensive, easily available arsenic oxides and without any complicated operations. The trialkylarsenic compounds thus obtained can be effectively used as a material for compound semiconductors in the field of electronic industry as well as in the field of various chemical industries, and are of great industrial value.
