  4. Methyl isocyanate - Wikipedia

    en.wikipedia.org/wiki/Methyl_isocyanate

    Methyl isocyanate (MIC) is an organic compound with the molecular formula CH 3 NCO. Synonyms are isocyanatomethane and methyl carbylamine . Methyl isocyanate is an intermediate chemical in the production of carbamate pesticides and Haffmann Bromamide Degradation (such as carbaryl , carbofuran , methomyl , and aldicarb ).

  5. Methylene diphenyl diisocyanate - Wikipedia

    en.wikipedia.org/wiki/Methylene_diphenyl...

    An isocyanate at the 4-position is approximately four times more reactive than the group at the 2-position due to steric hindrance. [4] In 4,4′-MDI and 2,2′-MDI, the two isocyanate groups are equivalent to each other, but in 2,4′-MDI the two groups display highly differing reactivities. MDI isomers and polymer

  6. GHS hazard statements - Wikipedia

    en.wikipedia.org/wiki/GHS_hazard_statements

    Hazard statements form part of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). They are intended to form a set of standardized phrases about the hazards of chemical substances and mixtures that can be translated into different languages.

  7. Blocked isocyanates - Wikipedia

    en.wikipedia.org/wiki/Blocked_isocyanates

    A blocked isocyanate can be added to materials that would normally react with the isocyanate such as polyols.They do not react at normal ambient room temperature. A formulation containing a blocked isocyanate is a single component material (and thus usually considered more convenient) but reacts like a two-component product but will not react until heated to the temperature required for ...

  8. Phenyl isocyanate - Wikipedia

    en.wikipedia.org/wiki/Phenyl_isocyanate

    The molecule consists of a phenyl ring attached to the isocyanate functional group. It is a colourless liquid that reacts with water. Phenyl isocyanate has a strong odor and tearing vapours, therefore it has to be handled with care. Characteristic of other isocyanates, it reacts with amines to give ureas. [2]
