With a total of 4 patents to his name, Padeken's work has had a substantial impact on industrial processes.

Latest Patents

One of his latest patents is titled "Process for the preparation of isocyanates in the gas phase." This innovative method involves producing meta-toluene-diisocyanate by reacting meta-toluenediamine with phosgene in the gas phase. The process requires that the meta-toluenediamine to be vaporized contains less than 0.5 wt. % of toluenediamine residue, a total of less than 0.2 wt. % of ammonia and cycloaliphatic amines, and less than 20 ppm of heavy metals. Additionally, at least 0.1 wt. % of the liquid meta-toluenediamine must not be vaporized, and this non-vaporized content must not be fed to the phosgenation reactor.

Another significant patent is "Process for the production of aromatic diisocyanates in the gas." This process involves the gas-phase reaction of the corresponding primary aromatic diamine with phosgene. The reaction occurs within a mean residence time of 0.05 to 15 seconds, and the aromatic diamine used contains less than 0.05 mole % overall of aliphatic amine containing no keto groups, per mole of primary amino groups.
