Process for producing esters of (meth) acrylic acid and polyhydric alcohols |
| abstract |
PCT No. PCT/EP89/01548 Sec. 371 Date Aug. 23, 1991 Sec. 102(e) Date Aug. 23, 1991 PCT Filed Dec. 15, 1989 PCT Pub. No. WO90/07485 PCT Pub. Date Jul. 12, 1990The invention relates to a process for the production of (meth)acrylic acid esters of polyhydric alcohols by reaction of the reactants with acrylic acid and/or methacrylic acid in the presence of acidic esterification catalysts with addition of sterically hindered phenolic compounds as polymerization inhibitors. The process is characterized in that tocopherols are used as the sterically hindered phenolic compounds and alpha -tocopherol is preferably at least partly used. The process is preferably carried out using reaction mixtures which are liquid at room temperature and which are at least substantially free from solvents and/or azeotropic entraining agents; more particularly, the water of condensation formed is removed from the gas phase of the reaction zone. |
