TL;DR: In this paper, a method for treating a C4 fraction, comprising the following steps: extractive distillation (I), selective hydrogenation on a heterogeneous catalyst (II), a stream of crude 1,3-butadiene resulting from steps (I and (II); and distillation of said stream of 1 3 butadiene in order to obtain pure 1 3 -butadienes (III).

TL;DR: In this article, a method for obtaining 1.3 pure butadiene from 1.5 raw butadienes by distillation is described. Butadiene extraction is carried out in a separating wall column, wherein separating wall is arranged in the longitudinal direction of the column in such a manner that it forms a common upper column area, a common lower column area and a feed part and a removal part.

TL;DR: In this paper , an in vitro battery was assembled from ten individual NAMs that had been developed during the past years to probe effects of chemicals on various fundamental neurodevelopmental processes, including proliferation of neural progenitor cells, migration of neural crest cells, radial glia cells, neurons and oligodendrocytes.

TL;DR: This study scientifically validate the Neurosphere Assay, which is based on human primary neural progenitor cells (hNPCs) and an integral part of the DNT in vitro screening battery is well poised for DNT evaluation for regulatory purposes.

TL;DR: In this article , the authors evaluated DNT hazards of two selected Chinese herbal medicines (CHMs) Lei Gong Teng (LGT) and Tian Ma (TM), and provided further insight into their modes of action.
