Noun
a salt or ester of isocyanic acid
Source: WordNetA third reaction, particularly important in making insulating rigid foams is the isocyanate trimerization reaction, which is catalyzed by potassium octoate, for example. Source: Internet
If water is present in the reaction mixture (it is often added intentionally to make foams), the isocyanate reacts with water to form a urea linkage and carbon dioxide gas and the resulting polymer contains both urethane and urea linkages. Source: Internet
Factors affecting catalyst selection include balancing three reactions: urethane (polyol+isocyanate, or gel) formation, the urea (water+isocyanate, or "blow") formation, or the isocyanate trimerization reaction (e. Source: Internet
Isocyanates Isocyanates used to make polyurethane have two or more isocyanate groups on each molecule. Source: Internet
Methyl isocyanate was the chemical released in the Bhopal disaster causing the death of nearly 4000 people. Source: Internet
Non-symmetric ureas can be accessed by reaction of primary or secondary amines with an isocyanate. Source: Internet
