| 发明名称 | Process for preparing (meth)acrylic esters | ||
| 摘要 | The invention relates to a process for preparing (meth)acrylic esters by esterifying (meth)acrylic acid or transesterifying at least one (meth)acrylic ester with at least one compound comprising at least one OH group in the presence of a heterogeneous catalyst comprising at least one inorganic salt, wherein the esterification or transesterification is performed in the presence of 300 to 3000 ppm of water based on the total weight of the reaction mixture. | ||

| 主权项 | 1. A process for preparing a (meth)acrylic ester by esterifying (meth)acrylic acid or transesterifying at least one (meth)acrylic ester with at least one compound comprising at least one OH group in the presence of a heterogeneous catalyst consisting of one or more inorganic salts selected from the group consisting of K3PO4, Na3PO4, K2CO3 and Na2CO3 and hydrates thereof, which comprises performing the esterification or transesterification in the presence of 300 to 3,000 ppm of water based on the total weight of the reaction mixture. | ||
