摘要： In the oxidation of propylene and/or acrolein, high-boiling or non-volatile byproducts are separated from the solvents used for absorbing the acrylic acid by treating the said solvents laden with byproducts with the hot reaction gases in such amounts that the major portion of the solvents evaporates, the residual solvent containing a high percentage of said byproducts then being discarded or worked up.

摘要： A bath container for cooling a liquid contained therein for use in refrigeration equipment includes a jacket bounding a space for the liquid which comprises a side wall and a bottom wall. The side wall of the jacket is formed of two individual walls spaced from one another to form a hollow chamber therebetween which chamber is connected to a refrigerant feeding member and to a refrigerant discharging member whereby the jacket forming the hollow chamber and adapted to pass the refrigerant therethrough functions as an evaporator. A surface heating element including a heating wire inserted into a relatively thick insulating packing is mounted on the surface of the bottom side to supply heat to the working liquid contained in the bath container.
摘要翻译：用于冷却其中容纳在其中用于制冷设备的液体的浴容器包括用于包围侧壁和底壁的用于液体空间的护套。护套的侧壁由彼此间隔开的两个单独的壁形成，以在它们之间形成中空室，其间连接到制冷剂供给构件和制冷剂排放构件，由此形成中空室并使其适于通过制冷剂通过其作为蒸发器起作用。包括插入相对厚的绝缘衬垫的加热线的表面加热元件安装在底侧的表面上，以将热量供应到容纳在浴容器中的工作液体。
