- PROCESS FOR HYDROCHLORINATION OF MULTIHYDROXYLATED ALIPHATIC HYDROCARBONS
-
A process for producing a chlorohydrin, an ester of a chlorohydrin, or a mixture thereof including the steps of contacting, in a hydrochlorination reactor, a multihydroxylated aliphatic hydrocarbon, an ester of a multihydroxylated aliphatic hydrocarbon, or a mixture thereof with a source of a hydrogen chloride, in the presence of a hydrophobic or extractable carboxylic acid catalyst is provided.

- Acetals oxidation into esters with electrophilic halogens
-
A preparative oxidation of dioxolanes groups into esters is described. Among the different electophilic halogens and solvents which have been tested, ICl/H2O in methylene chloride and Br2/H2O in acetonitrile gave the best results.
