The entropy and related thermodynamic properties of methylisocyanate, CH3NCO, have been determined by isothermal calorimetry. The entropy in the ideal gas state at 298.15 K and 1 atmosphere is S-m(o) = 284.3 +/- 0.6 J/K . mol. Other thermodynamic properties determined include: the heat ...
Draw a Lewis structure for methyl isocyanate, CH3NCO, showing all valence electrons. Predict all bond angles in this molecule and the hybridization of each C, N, and O. Draw the Lewis structure for BrO4-. Draw the Lewis structure of C2H4 and identify its geometry. ...
Draw a Lewis structure for methyl isocyanate, CH3NCO, showing all valence electrons. Predict all bond angles in this molecule and the hybridization of each C, N, and O. Draw and explain the Lewis structure of SeF2. Determine its molecular geometry, hybr...
A series of substituted phenyl N-methyl carbamates were synthesized by the reaction of methyl isocyanate and the appropriate phenols. Biological experiments showed that the introduction of any substituent in the phenyl ring of the carbamates tested increased the inhibition activity to cholinesterase, whi...
The predominant biological effect of methyl isocyanate (MIC) intoxication in mammals is severe tissue hypoxia leading to acute lactic acidosis (Jeevarathinam et al 1988; 5eevaratnam et al 1990). In rabbits administered MIC subcutaneously (s.c.) the hypoxia was shown to be of the stagnant type...
It was observed that bio-based PU exhibited a lower degree of phase separation and slightly lower thermal stability compared to PUs from petrochemical monomers.Similar content being viewed by others Non-isocyanate polyurethanes synthesized from terpenes using thiourea organocatalysis and thiol-ene-chemistry...
HC Brown,R Bernheimer,KJ Morgan - 《Journal of the American Chemical Society》 被引量: 253发表: 1965年 Process for the partial carbodiimidization of organic isocyanates The present invention relates to a new process for the partial carbodiimidization of the isocyanate groups of organic mono-, ...
The nitrogen 14N quadrupole hyperfine structure and the Stark effect in the rotational spectra of methyl isocyanate and methyl isothiocyanate were investigated by high resolution microwave Fourier transform spectroscopy. The components o... BARBARA GRUNEWALD - 《Zeitschrift Für Naturforschung A》 被引量:...
Amino groups in 16 and 17 were transformed to the corresponding isocyanate (not shown) in the presence of BTC, and then reacted with memantine to respectively give compounds 18 and 19, which were hydrolyzed under basic conditions to affording the desired acid intermediates. Chlorination of the ...
of silanes were primarily localized on the surface of the starch structure. The best hydrophobic properties were obtained for the paper coated with the composition based on starch and methyltrimethoxysilane. This coating also improved the bursting resistance and compressive strength of the tested paper....
