-
Page/Page column 4-5, (2010/02/17)
The invention relates to a method for producing acyl peroxides. According to said method, an acyl compound is reacted with an organic hydroperoxide and a base, the pH of the two-phase mixture so obtained is adjusted to 6 to 13, the obtained organic phase is extracted with an aqueous solution of a base and the aqueous extract is recirculated to the reaction step. The method according to the invention allows the recirculation of unreacted hydroperoxide to the reaction step.

, (2008/06/13)
The invention relates to a process for the preparation of a tertiary perester by contacting an acyl compound with a tertiary hydroperoxide in the presence of an enzyme catalyst. The acyl compound has the formula R1[C(O)OR2]n, wherein R1is a linear or branched, saturated or unsaturated C1-C22group, optionally containing one or more hetero atoms, R2represents hydrogen or has the same meaning as described for R1, and n is 1-5, or a polyalcohol ester of R1C(O)OH, wherein R1has the same meaning as described above. The tertiary hydroperoxide has the formula [HOOCR3R3]mR4, wherein R3represents either a methyl or an ethyl group, R4has the same meaning as described for R1, and m is 1-5.

Decomposition rates and products of t-alkyl 2,2-dimethylperoxypropionates were measured in cumene at several temperatures.The peroxyesters decomposed homolitycally, depending on the structure of the t-alkyl moiety.The relative rates of the t-alkyl moieties to the 1,1-dimethylethyl one were: 1,1-dimethylbutyl (1.14), 1,1-dimethylpropyl (1.19), 1,1,2-trimethylpropyl (1.85), 1,1,3,3-tetramethylbutyl (2.10), and 1,1-dimethyl-2-phenylethyl (2.34).The decomposition showed an isokinetic relationship and the importance of stabilization by hyperconjugation.Based on these data, the decomposition mechanism, which contains a slight stretching of the Cα-Cβ bond to the peroxyl oxygen at the transition state is, discussed.
