Description of key information
In protic solvents like alcohols, isocyanates react rapidly. Stablility is expected with non-protic solvents like toluene, acetone, dioxane etc. Isocyanates form urethanes in alcohol. The concentration of HDI trimer in an acetonitrile solution without addition of water was stable within 26 hours.
