Phosgenation reactions

We receive orders to carry out custom synthesis of chemicals derived from phosgene, which is difficult to manage on a small-lot production basis. Four sets of reaction vessels (400, 2,000, 4,000, and 6,000 liter capacity) are capable of handling phosgenation.

What is phosgene?

Phosgene is a useful reagent that is capable of synthesizing chemicals, such as isocyanate and chloroformate, easily and at high quality levels. Chemicals that are derived from phosgene are used in a wide range of fields as raw materials for synthetic resins, such as polyurethanes and polycarbonates and for medicines and pesticides.
