Phenylisocyanate

Webinated with the relatively volatile substance, phenylisocyanate. These days, however, the level of phenylisocyanate is generally well below 0.005 % w/w and so is irrelevant for the assessment of the effects of these substances on occupational health. The spontaneous chemical reaction of the various kinds of MDI with primary or Phenyl isocyanate is an organic compound typically abbreviated PhNCO. 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. … Zobraziť viac PhNCO is a planar molecule, according to X-ray crystallography. The N=C=O linkage is nearly linear. The C=N and C=O distances are respectively 1.195 and 1.173 Å. Zobraziť viac • Phenyl Isocyanate Data Sheet Zobraziť viac
