METHOD FOR DETERMINATION OF ALKYLPEROXIDES Russian patent published in 2007 - IPC G01N31/16 C07C409/20

Abstract RU 2296989 C1

FIELD: analytic chemistry.

SUBSTANCE: invention relates to method for determination of alkylperoxides and alpha-alcoxydialkylperoxides of general formula (CH₃)₃C-O-O-C(CH₃)R₁R₂, wherein R₁and R₂represent CH₃; R₁represents hydrogen; R₂represents OCH₃, OCH₂-CH(CH₃)₂, O-cyclo-C₆H₁₁, OC₆H₅, OCH₂-(CH₂-O-CH₂)₂-CH₂OH, OCH₂-CH(OH)-CH₂OH. Claimed method includes peroxide treatment with potassium iodide in presence of acetic acid and sodium bicarbonate followed by iodimetric titration; followed by addition of 40 % aqueous solution of hydrogen bromide in mass ratio to tested substance of 70:1, respectively, and conditioning at 70°C for 15 min. Method of present invention makes it possible to reduce acetic acid consumption by 2.5 times and decrease analysis temperature from 90°C to 70°C.

EFFECT: improves method for determination of alkylperoxides.
