METHOD FOR PREPARING ALPHA-ALKOXYDIALKYLPEROXIDES Russian patent published in 2006 - IPC C07C409/20

Abstract RU 2284321 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of α-alkoxydialkylperoxides comprising alkoxyl or phenoxyl group in structure of the general formula:

wherein R means CH₃, C₂H₅, C₃H₇; R' means CH₃, cyclo-C₆H₁₁, CH₂-CH=CH₂, C₆H₅, CH₂-(CH₂-O-CH₂)₂-CH₂OH, CH₂-CH(OH)-CH₂OH. Method involves interaction of α-chloroalkyl-tert.-butylperoxides with alcohols in chloroform medium. As α-chloroalkyl-tert.-butylperoxide the method involves using α-chloroethyl-tert.-butylperoxide, α-chloropropyl-tert.-butylperoxide, α-chlorobutyl-tert.-butylperoxide, and methyl, isobutyl, cyclohexyl, allyl alcohols, phenol, triethylene glycol and glycerol are used as alcohol. Reaction is carried out using calcium carbonate as acceptor of hydrogen chloride at temperature 20-30°C for 30 min in the mole ratio α-chloroalkyl-tert.-butylperoxide : alcohol : calcium carbonate = 1:1:(0.51-0.58), respectively. Invention provides enhancing yield of the end product (above 90%) and decrease amount of sewages.

EFFECT: improved method of synthesis.
