Useful:

• Chemical Classes: Toxic Gases & Vapors -> Monoisocyanates
• Canonical SMILES: CCN=C=O
• Uses: Ethyl isocyanate is part of a group of isocyanates that react with primary and secondary amines to form urea derivatives and carbamates. Ethyl isocyanate (among other isocyanate compounds, such as toluene isocyanate) are also thought to be the most common cause of occupational asthma. Pharmaceutical and pesticide intermediate.

Technology Process of Ethyl isocyanate

There total 64 articles about Ethyl isocyanate which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:
