Aromatic isocyanate synthesis stoichiometry: BASFRecent Research Landscape

Side reactions during phosgenation create yield loss and downstream purification bottlenecks. Precise control of the amine-to-phosgene ratio and thermal profile ensures high conversion to aromatic polyisocyanates while minimizing byproduct formation.

What technical problems is BASF addressing in Aromatic isocyanate synthesis stoichiometry?

Low reaction yield

(6)evidences

Excess unreacted monomeric isocyanates in polyisocyanate products pose significant health risks and environmental hazards. Reducing these levels ensures regulatory compliance and improves safety profiles for downstream applications.

Hazardous byproduct formation

(5)evidences

Conventional carbodiimide production requires multi-stage processing and excessive thermal input. Reducing these inefficiencies minimizes operational costs and thermal degradation.
