摘要：
The invention relates to a device comprising a feed which is arranged below the center of the device, a quenching agent inlet which is arranged above the feed, an outlet which is arranged below the feed, and a discharge which is arranged above the quenching agent inlet, said device having a region provided with one or more packets between the quenching agent inlet and the feed. The device is characterized in that at least one means is provided between the quenching agent inlet and a packet provided between the quenching agent inlet and the feed, said means ensuring the formation of a liquid layer with a height of at least 1 cm. The invention further relates to a method for producing acrylic acid, having a step of oxidizing acrolein, wherein the reaction mixture obtained from the oxidation process is brought into contact with water as the quenching agent in a device according to the invention, and to a composition which can be obtained as a bottom product in the method according to the invention, said composition containing acrylic acid and water.
摘要（中）：
本发明是包括设置以下装置的中心的供料器的装置，一个Quenchmittelzulauf，其是设置在进料的上方，在进料点下方的出口，其被设置在上述Quenchmittelzulaufs的触发，其中 Quenchmittelzulauf并且具有与一个或多个软件包的区域进料之间的装置被提供，其设置在Quenchmittelzulauf和Quenchmittelzulauf之间现有和喂养组之间，其特征在于，至少一种试剂存在时，它是具有一个液体层的形成 保证至少1cm的高度。 此外，本发明是一种用于生产丙烯酸，包括丙烯醛的氧化反应，其中在该氧化获得的反应混合物在本发明的设备使用水作为在接触猝灭剂带来的步骤，以及一个组合物得到作为塔底产物的方法中的 本发明的方法含有丙烯酸和水。
