Methylene Diphenyl Diisocyanate

Product Details:

Total world production of MDI and polymeric MDI is over 5 million tonnes per year (Mt/a in 2011). The largest producer is Covestro (ex Bayer MaterialScience) followed closely by Yantai Wanhua.^[5] Other major producers are BASF, BorsodChem, Dow, Huntsman, Nippon Polyurethane Industry, OCI. All major producers of MDI are members of the International Isocyanate Institute, whose aim is the promotion of the safe handling of MDI and TDI in the workplace, community and environment.
The first step of the production of MDI is the reaction of aniline and formaldehyde, using hydrochloric acid as a catalyst to produce a diamine precursor under the chemical formulation:
2 C₆H₅NH₂ + CH₂O → CH₂(C₆H₄NH₂)₂ + H₂O
