FIELD: chemical or physical processes.
SUBSTANCE: invention relates to a method of producing a stabilized organophosphorus composition and can be used in chemical industry. Proposed method comprises: preparation of solution from raw materials, including solvent, alkanolamine and ligand raw material containing hydrolysable organophosphorus ligand, wherein total acidity of raw materials is at least 200 parts per million by weight phosphorous acid based on weight of ligand, wherein concentration of alkanolamine in solution ranges from 0.025 to 1 wt % per total weight of solution, and solution does not contain transition metals; and additionally supplying ligand solution into hydroformylation process.
EFFECT: novel efficient method of producing a stabilized organophosphorus composition.
