Claim:
An oxidation reaction process catalyzed by reaction controlled phase-transfer catalyst, characterized in that the reaction process comprises the steps of: (a) reacting an oxygen source with a substrate in the presence of a reaction controlled phase-transfer catalyst at a temperature of −20° C. to 110° C. in reaction medium of a homogeneous phase or water/oil two phase, to yield a product; and (b) separating out the reaction controlled phase-transfer catalyst by centrifugation or filtration after the completion of the reaction, wherein the catalyst can be recycled; wherein the reaction controlled phase-transfer catalyst is heteropolyacid compounds with formula of [R 1 R 2 R 3 R 4 N] x H y [A], wherein R 1 , R 2 , R 3 , and R 4 are independently C 1 -C 20 linear or branched alkyl, cycloalkyl, or benzyl; or R 1 R 2 R 3 N is pyridine or its homologue; A is a heteropolyanion group of P or As containing metal atom of Mo, W or V; x is an integer of from 1 to 9, and y is an integer of from 0 to 8, with the proviso that said heteropolyacid compounds do not contain active oxygen prior to their use in the oxidation reaction; or a complex represented by the general formula of Q m MO 3 (L), wherein M is a central metal atom selected from the group consisting of Mo and W atom; Q is a cation moiety of formula [R 1 R 2 R 3 R 4 N + ], in which R 1 , R 2 , R 3 , and R 4 are C 1 -C 20 linear or branched alkyl, branched alkyl, cycloalkyl, or benzyl, or R 1 R 2 R 3 N is pyridine or its homologue; and L is a bidentate ligand containing N or O; when L is N,N-bidentate ligand, it includes R 1 ,R 2 -2,2′-dipyridine (R 1 and R 2 can be substituents such as H—, C 1 -C 20 linear or branched alkyl group, cycloalkyl group, aryl group etc. at the position of 2 to 9), R 1 , R 2 , R 3 -o-phenanthroline (R 1 , R 2 , and R 3 can be substituents such as H—, C 1 -C 20 linear or branched alkyl group, cycloalkyl group, aryl group etc. at the position of 2 to 9), m=0; when L is N,O-bidentate ligand, it includes 8-hydroxy quinoline, 2-carboxy pyridine, Schiff base formed from salicylaldehyde or substituted salicylaldehyde with primary amine and the like, m=1; when L is O,O-bidentate ligand, it includes β-carbonyl ketone or ester, m=1.
