Process For Making Polyol Esters With Improved Colour And Odour Quality |
| abstract |
Suggested is an improved process for making polyol esters with improved colour quality by transesterification of polyols or their alkoxylation products with fatty acid alkyl esters, which is characterised in that the reaction is carried out in the presence of a reducing mineral or organic acid as a catalyst selected from the group consisting of (i) sulphuric or sulphonic acids with an oxidation value of sulphur of less than 6 or their salts, and/or (ii) phosphoric or phosphonic acids with an oxidation value of phosphor of less than 5 or their salts. |
