FIELD: crude oil preparation. SUBSTANCE: to iron-containing crude oil, chelate-forming agent is added composed of phosphone-methylated derivative of 1,3-diamino-2-propanol with general formula 
where n = 1-5 and 1,3-diamino-2-propanol derivative with general formula 
where n = 1- 5 at weight ratio 1:(0.1-0.2). Thereafter, iron-containing crude oil is combined with hydrogen sulfide-containing crude oil, demulsifier is added, and resulting mixture is settled. EFFECT: improved quality of commercial petroleum and reduced chelate-forming agent consumption. 3 tbl
