FIELD: synthesis of biologically active chemical compounds, more particularly pharmacology, medicine and agriculture. SUBSTANCE: benzyl benzoate is prepared by reacting benzyl alcohol with benzoyl chloride in aqueous alkaline solution. Process is first carried out at 13-16 C for 1.0-1.5 hours, and sodium hydroxide is then added to system at 1.9-2.1 ratio to benzoyl chloride and resulting mixture is maintained for 0.8-1.2 hours, reaction mixture thus formed is heated to 50-60 C and maintained at given temperature for 1.0-1.5 hours. Yield of benzoyl benzoate is increased to 95-97%. EFFECT: more efficient preparation method. 12 ex, 1 tbl
