Latest Patents

Hauner's latest patents include a revolutionary process for decreasing the chlorine content of organic isocyanates. This method involves mixing isocyanates or isocyanate mixtures with a gel-type or macroporous anion-exchanging organic material, which contains tertiary and/or quaternary amino groups. This process allows for a milder purification of isocyanates from chlorine-containing compounds, which is particularly beneficial for temperature-sensitive isocyanates.

In addition to this, Hauner has developed a process for the continuous catalyst-free production of polyisocyanates. This method utilizes the thermal decomposition of N-substituted carbamic acid esters corresponding to the polyisocyanates. The innovative technique involves heating the carbamic acid esters in a solution with an inert high-boiling solvent, followed by their introduction into a distillation column under controlled pressure and temperature conditions. This ensures continuous and selective condensation of the decomposition products, showcasing Hauner's advanced understanding of chemical engineering.
