Title: The Innovations of Jurgen Lahrs: A Pioneer in Organic Isocyanate Production

Introduction

Jurgen Lahrs, an accomplished inventor based in Cologne, Germany, has made significant contributions to the field of chemical engineering, particularly in the production of organic isocyanates. With a total of four patents to his name, Lahrs has been instrumental in developing innovative processes that enhance product quality and efficiency.

Latest Patents

Among his latest innovations, one notable patent is for a **continuous process for the production of organic isocyanates**. This process involves phosgenating corresponding amines in a continuous manner. In this method, a solution of the amine is continuously sprayed through a smooth-jet nozzle into a stream of phosgene that flows through a mixing chamber at controlled temperatures and pressures. The optimal conditions maintain the temperature between 120 to 300 degrees Celsius and the pressure between 10 to 1000 bars, resulting in a highly efficient production of organic mono- or poly-isocyanates.

Another important patent attributed to Lahrs is the **process for the manufacture of preparations with a low dust content**. This innovation addresses the challenge of dust in pulverulent preparations, particularly dyestuff powders. By allowing customary dustproofing agents to act on the pulverulent product in aerosol form rather than applying them before drying, Lahrs has significantly improved the quality of the final product. The average particle size of the aerosol in this process is less than 10 micrometers, fulfilling the need for low-dust solutions in various applications.

Career Highlights

Jurgen Lahrs currently works for Bayer Aktiengesellschaft, a multinational company known for its research and development in pharmaceuticals and agricultural products.
