摘要： For the distillation of temperature-sensitive liquids, in particular acrylic acid and its esters, the liquid is heated in a column and at least partly evaporated. The vapor is guided through a condenser provided inside the column, in which the vapor is at least partly condensed. The condensed liquid is at least partly withdrawn from the column. The distillation is characterized in that the vapor not condensed yet is guided through the condenser cocurrently to the condensed liquid.

摘要： A tubular reactor for carrying out a catalytically supported, homogeneous chemical reaction in the gas phase at an elevated temperature and a subsequent cooling, wherein the reactor is arranged upright, and therefore the tubes extend vertically and the as flows downward through the tubes. The tubes are filled with a catalyst bed in the upper part thereof extending in the reaction zone of the reactor and are filled with a structured packing in the lower part, the cooling zone of the reactor.
