Abstract: A process for the rectification and sepn. of unsatd. carboxylic acids (I) from the solvents in which (I) are absorbed after the synthesis reaction. The process involves interrupting the rectification and flushing out the rectification column with basic soln.

Abstract: Reactor arrangement comprises at least two tubular reactors filled with solid particles, at least one reactor containing a temperature measuring device. The novelty is that the tubular reactors are arranged so that the ratio of the composition of the solid particles to the free cross-sectional surfaces of each reactor as well as the pressure loss, measured by passing an inert gas proportionally transversal to the free cross-sectional, are equal over each tubular reactor. Also claimed is a process for treating fluid compositions with the production and consumption of thermal energy using the above reactor arrangement.
