摘要： Process for the purification of toluenediisocyanate from a crude distillation feed which includes toluenediisocyanate, an organic solvent and less than 2% by weight phosgene by separating the crude distillation feed in a dividing-wall distillation column into at least four product fractions P1–P4. P1 is a phosgene enriched low-boiler product, P2 is a solvent-enriched product, P3 is a high boiler enriched bottoms and P4 is a toluenediisocyanate product stream.

摘要： One or more fluid streams are uniformly divided into two or more partial fluid streams in chemical apparatuses in a manner such that there is a reduced tendency to form deposits. Division of such stream(s) is achieved by using a distributor device that includes at least one plate having two or more openings which openings are rounded or chamfered on at least one side.
