Disclosed is a process for making vinyl carboxylate esters such as vinyl acetate and vinyl propionate, by a reactive distillation process comprising a reaction zone wherein a vinyl carboxylate ester is formed from a carbonyl compound selected from aliphatic aldehydes and ketones and an anhydride of an aliphatic carboxylic acid and a distillation zone from which the vinyl carboxylate ester is recovered and substantially separated from other compounds contained within the column. The process requires significantly less equipment than known, analogous processes and thus the cost of constructing a plant for the operation of the present process is substantially reduced.

Process for generating vinyl carboxylate esters

A distillation process for the separation of acetic anhydride from a mixture thereof with ethylidene diacetate wherein the mixture of acetic anhydride and ethylidene diacetate is fed to the mid section of a distillation column and a small amount of acetic acid is fed separately to the lower section of the column. The addition of the acetic acid suppresses tar formation during the distillation process.

Disclosed is a process for the co-production of aromatic carboxylic esters and alkyl iodides by the carbonylation of aromatic iodides in the presence of an alkanol and a palladium catalyst.

Process for the coproduction of aromatic carboxylates and alkyl iodides

Disclosed is a process for the co-production of aromatic carboxylates and alkyl iodides by the carbonylation of aromatic iodides in the presence of an alkanol and a nickel catalyst.

Process for the co-production of aromatic carboxylates and alkyl iodides

The process relates to a process for the vapor phase bromination of aromatic compounds in the presence of oxygen and a catalyst comprising an oxidizing metal and an inert support.

Vapor phase bromination of aromatic compounds

The invention relates to a process for isomerizing and transiodinating iodoaromatic compounds over a non-acid catalyst.

Process for preparing iodinated aromatic compounds

A process for iodinating an aromatic compound in which a source of iodine is reacted with the aromatic compound in the presence of oxygen over a non-acid catalyst wherein the aromatic compound has a fluoro, chloro, bromo, iodo, hydroxy or cyano group.

Process for preparing iodinated substituted aromatic compounds

This invention relates to a process for iodination of aromatic compounds in the presence of oxygen over a zeolite catalyst.

Processes for preparing iodinated aromatic compounds

This invention relates to a novel carbonylation process for the production of aromatic carboxylic acids or esters of aromatic. More particularly, this invention relates to a process for the carbonylation of aromatic iodides or bromides with carbon monoxide in the presence of a palladium catalyst promoted with a Group VIB carbonyl and in the presence of an alcohol or water in a base reaction medium having a pKa greater than about 8. When the alcohol is used the product is the ester. When water is used the product is the carboxylic acid.

Carbonylation process for the production of aromatic acids or esters
