Abstract: The invention relates to a device for separation of substance mixtures on the micro scale. The invention further relates to a process for separating substance mixtures using the inventive device. The device is a device for separating substance mixtures and for performing chemical reactions between immiscible fluid media on the micro scale, comprising a first channel plate with at least one first process channel for a first fluid medium, an inlet and an outlet, and a connecting or distributing channel in each case, which connects the inlet to the first process channel, and a further connecting or distributing channel which connects the first process channel to the outlet, a second channel plate with at least one second process channel for a second fluid medium immiscible with the first, an inlet and an outlet, and a connecting or distributing channel in each case, which connects the inlet to the second process channel, and a further connecting or distributing channel which connects the second process channel to the outlet, and a microscreen as a separating means between the two process channel, wherein the microscreen has a multitude of orifices which have an aspect ratio of 1.5 to 10.

Abstract: Toluene diisocyanate is recovered from a crude distillation feed containing less than 2% by weight of phosgene by(a) fractionating the crude distillation feed containing less than 2% by weight of phosgene to remove the solvent and optionally the reaction residues to produce a crude toluene diisocyanate feed containing less than 20% by weight of solvent and(b) separating the crude toluene diisocyanate feed containing less than 20% by weight of solvent in a divided-wall distillation column into four product fractions P1–P4. P1 is a vapor phase low-boiler and solvent-enriched gas stream, P2 is a low-boiler and solvent-enriched product, P3 is a high boiler-enriched bottoms product containing toluene diisocyanate and P4 is a toluene diisocyanate product stream lean in low-boilers, high-boilers and reaction residues.
