Esterification process with calcium hydroxybenzyl phosphonate-phenol sulfide catalyst system |
| abstract |
An esterfication process particularly for the preparation of rosin esters, polyesters and polymeric esters wherein aliphatic or aromatic carboxylic acids are reacted with appropriate alcohols in the presence of catalytic amounts of a mixture of a calcium bis[monoethylÂ(3,5-di-tert-butyl-4-hydroxybenzyl) phosphonate] and a phenol sulfide, the presence of said mixture serving to reduce the time necessary for complete esterification and to provide esters with increased oxidation stability and better color. |
