Improved process for producing esters of (meth)acrylic acid and polyhydric alcohols (i) |
| abstract |
In a process for producing esters of (meth)acrylic acid of polyhydric alcohols, the reagents are converted in the presence of acidic esterification catalysts, alpha-substituted phenolic compounds, in particular di-tert.-butylhydroquinone, being added as polymerization inhibitors. The novel process is characterized in that the reaction mixtures are liquid at the reaction temperature and are essentially free from solvents and/or azeotropic entrainers, the water of condensation being removed from the gaseous phase in the reaction chamber. |
