Latest Patents

Biskup's latest patents showcase his expertise in the gas-phase preparation of isocyanates. One notable patent involves the process for creating meta-toluene-diisocyanate by reacting meta-toluenediamine with phosgene. This innovative methodology requires strict specifications for vaporized meta-toluenediamine, ensuring minimal impurities by limiting the toluenediamine residue to less than 0.5 wt. %, ammonia and cycloaliphatic amines to below 0.2 wt. %, and heavy metals to less than 20 ppm. Moreover, it states that at least 0.1 wt. % of the liquid meta-toluenediamine must not be vaporized to optimize the process.

Another key patent focuses on the production of aromatic isocyanates through the gas-phase reaction of one or more aromatic primary amines with phosgene. In this process, the reaction occurs above the boiling temperature of the amines in a specially designed reactor for efficient conversion. It maintains a specific flow rate within the reactor, ensuring that the conversion of amine groups into isocyanate groups stays within the optimal range, enhancing productivity and safety.
