Triglyceride and other polyol ester PVC plasticizers can be produced by recovery of branched C6 to C9 aldehydes from a hydroformylation product, optional hydrogenation to the alcohol, oxidation to the acid with oxygen and/or air, recovery of the resulting acid, and esterification with glycerol, ethylene glycol, propylene glycol or mixtures thereof. The branched alkyl chains comprise at least 10% methyl branching. Special triglycerides are derived from branched aliphatic acids having alkyl chains with average carbon numbers from 6 to 9 and at least 10% methyl branching. These triglycerides are fast fusing plasticizers if before esterification with glycerol, an aryl acid is introduced together with the aliphatic acids.

Polyol ester plasticizers and process of making the same

The present invention relates to alcohols and in particular to Cto Calcohols that are used in the production of esters.

Processes relating to alcohols for the production of esters

The use of a controlled amount of water in a hydrogenation stage of the oxo process for the production of alcohols which uses at least two reactors in series improves the efficiency of the hydrogenation reaction and catalyst life as does a reduction in the amount of sulphur, chlorine and hydroformylation catalyst residues in the feed to hydrogenation.

Hydrogenation

Co-precipitated CoCuMn and CoCuMg catalysts are used in Fischer-Tropsch synthesis.

Catalysts and processes using them

The present invention provides a process for preparing an overbased barium complex and an overbased barium complex prepared thereby. The process includes the steps of: heating a mixture of barium hydroxide monohydrate and an isomeric mixture of from about C to about C alcohols in the presence of a solvent, thereby producing a first mixture; contacting the first mixture and an isomeric mixture of from about C to about C branched carboxylic acids, thereby producing a second mixture which includes unreacted barium hydroxide; and contacting the second mixture and carbon dioxide, thereby producing the overbased barium complex. The overbased barium complex of the present invention is useful in the stabilization of halogen-containing polymers.

Overbased barium complexes of C8 to C10 carboxylic acids

Esters of branched C,alcohols suitable as plasticizers are formed by esterification of a C,alcohol produced by the aldol condensation from propanal and a C,aldehyde and hydrogenation, the propanal optionally having been made from natural gas streams.
