Reaction Steps
A solution of 1.00 g phenylisocyanate in 50 ml dry toluene was prepared. Several dilutions of the stock isocyanate solution were made and an infrared absorbance versus concentration curve was obtained using the IR absorbance at 2265 cm-1 divided by the IR cell path length (in cm). The slope of this line gave a concentration factor of 0.118 mmole isocyanate/absorbance unit cm-1.
