Zusammenfassung: | FIELD: organic chemistry. SUBSTANCE: product - bis-[3-(3,5- dimethyl -4-hydroxyphenyl) -propyl-1] -sulfide (I) of the formula [(3,5-2 CH), (4-OH)-CH-(CH)]S,, empirical formula is CHOS, yield is 75.5% ; 3-(3,5-dimethyl -4-hydroxyphenyl)-propanol-1 (II) of the formula (3,5-2 CH), (4-OH) -CH-(CH)-OH, empirical formula is CHO, yield is 29.7% , b. p. is 130-155 C/1-2 mm mercury column. Synthesis of compound (I): compound (II) is treated with thionyl chloride following by interaction of prepared 4-(γ-chloropropyl)-2,6-di-tert. -butylphenol with sodium sulfide. Synthesis of compound (II): 2,6-dimethylphenol is treated with allyl alcohol. Method is used for synthesis polymer stabilizing agents, in part, sevilen (copolymer of vinyl acetate and ethylene). EFFECT: improved method of synthesis. 3 cl, 2 tbl
