- Temperature-controlled solvent-free selective synthesis of tert-butyl peresters or acids from benzyl cyanides in the presence of the TBHP/Cu(OAc)2 system
-
Solvent-free room temperature synthesis of tert-butyl peresters was achieved via copper-catalyzed oxidative-coupling of benzyl cyanides with tert-butyl hydroperoxide in short reaction times. Various derivatives of tert-butyl peresters were synthesized by this pathway in good to excellent yields. Further investigation revealed that the above-mentioned protocol is effective for the synthesis of benzoic acid derivatives when the reaction is conducted at 80?°C, under the same reaction conditions.

- Batch process for manufacturing and purifying liquid organic peroxide by distillation
-
A batch process for the manufacture of liquid organic peroxides, such as peroxy esters and diacyl peroxides, by reacting an acid chloride, a hydroperoxide and an alkali metal hydroxide uses a countercurrent, packed distillation column for recovering a purer, drier product with higher yield than previous batch drying processes.

- Continuous manufacture of peroxyesters
-
A continuous solvent-free process for the manufacturing of peroxyesters from an acid chloride, a hydroperoxide and an alkali metal hydroxide generates a pure product of good quality, high yields and throughput per unit volume of the reactor. The process comprises at least two reactors and a physical separation unit for separating the high purity product.
