There is disclosed a process for the co-production of long chain ω-amino acid and long chain dibasic acid, comprising: (1) reacting long chain ketoacid derivative with hydroxylamine or subjecting ketoacid derivative to an ammoximation to yield oxime derivative; (2) subjecting oxime derivative to Beckmann rearrangement to yield a mixture of mixed amide derivatives; (3) hydrolyzing the mixed amide derivatives to produce long chain ω-amino acid and long chain dibasic acid.
