本発明は、物質交換トレーの連続を含有する分離塔中の上昇性ガス状物質流の少なくとも1つと、前記分離塔中の、重合阻害剤を溶解して含有する下降性液状物質流の少なくとも1つとの間で熱分解するにあたり、前記物質流のうち少なくとも1つは(メタ)アクリルモノマーを含有し、分離塔の内面は、前記の、分離塔中の、重合阻害剤を溶解して含有する下降性液状物質流で吹き付けられていて、かつその際分離塔は内部構造体を有し、前記内部構造体は少なくとも一部の面が、前記の、吹き付けた下降性液状物質流の陰の領域にある熱分解方法に関する。
1.比較例
3.8mの内径及び32mの長さを有する精留塔中で混合物を分離し、前記混合物は以下の成分を含有した:
アクリル酸17質量%、
水0.02質量%、
アクロレイン0.0015質量%、
アリルアクリラート0.0015質量%、
フルフラール0.01質量%、
酢酸0.027質量%、
ベンズアルデヒド0.2質量%、
プロピオン酸0.003質量%、
無水マレイン酸0.032質量%、
Diphyl(R)(ジフェニル約25質量%及びジフェニルエーテル約75質量%からの混合物)58質量%、
ジメチルフタラート17質量%、
アクロロイルプロピオン酸(Acroloylpropionsaeure)3質量%、及び
フェノチアジン300質量ppm。
比較例のように行われた。二重T字型支持体は、しかし、図2のように鋼プレートでカバーされていた。プレート厚さは2mmであった。縁に、プレートは溶接された。40日間の運転時間の後でも、二重T字型支持体は重合体を有しなかった。
Claims (5)
