摘要: THIS INVENTION RELATES TO A PROCESS FOR THE MANUFACTURE OF PERESTERS AND MORE PARTICULARLY TO SUCH A PROCESS WHEREIN THE PERESTERS ARE PREPARED BY REACTION BETWEEN AN ORGANIC HYDROPEROXIDE AND A CARBOXYLIC ACID. IN PARTICULARLY PREFERRED EMBODIMENTS, THIS INVENTION RELATES TO PROCESSES FOR THE MANUFACTURE OF TERTIARY ALKYL PERESTES AND TO SECONDARY AND TERTIARY ARALKYL PERESTERS. THUS, THIS INVENTION IS ESPECIALLY APPLICABLE TO THE MANUFACTURE OF SUCH PERESTERS AS, FOR EXAMPLE, T-BUTYL PERACETATE, T-BUTYL PERBENZOATE, ETHYLBENZYL PERPIVALATE AND CUMYL PERISOBUTYRATE.

摘要: When vicinal glycol esters are prepared by the liquid phase reaction of (a) ethylene or propylene, (b) molecular oxygen and (c) a carboxylic acid in the presence of a catalyst system which is tellurium cation plus bromide anion or selenium cation plus chloride anion or selenium cation plus bromide anion, significant improvements in selectivity and operability are obtained by employing, in conjunction with these catalyst systems, a basicity control cation of specified characteristics. This cation is employed in an amount at least sufficient to provide at least 0.05 equivalent of cation per gram-atom of halogen present.
