Title: Vanessa Simone Lehr: Innovating Isocyanate Production

Introduction: Vanessa Simone Lehr is a notable inventor based in Mannheim, Germany. With a remarkable portfolio of six patents, her contributions to the field of chemistry, specifically in the production of isocyanates, are significant. Lehr's innovative processes demonstrate her commitment to advancing chemical manufacturing techniques.

Latest Patents: One of Vanessa's latest patents focuses on "Process for preparing isocyanates." This invention relates to the gas phase phosgenation of amines for the efficient preparation of isocyanates. In this process, phosgene is generated by reacting chlorine with an excess of carbon monoxide in a gas phase. The resulting phosgene-containing reaction mixture is divided into two distinct streams through a thermal or membrane separating process.

The first stream consists of a low-carbon monoxide concentration of no more than 1% by weight, serving as the phosgene-containing reactant in the gas phase reaction with amines. Meanwhile, the second stream, which is rich in carbon monoxide (more than 10% by weight), can be recycled back into the synthesis of phosgene. This innovative approach highlights the efficiency of the process and its potential for reducing waste in industrial applications.

Career Highlights: Vanessa Simone Lehr is associated with BASF SE Corporation, a leading company in the chemical industry.
