The water formed in the reaction hydrolyzes some of the cyclopropyl cyanide, so that after 1 hour''s heating very little liquid is apparent. The hydrolysis of the cyanide is completed by the addition of water in small portions over a period of about 2 hours and subsequent heating 15–20 ml. of water is added at first, and portions of 60–75

Raman spectra of liquid cyclopropyl cyanide Maillols

The Raman spectra of liquid cyclopropyl cyanide (range 50–4000 cm −1) are reported and found considerably different from those published by Daly and Wiberley. 1 A new assignment is given based on the study of both Raman and IR spectra (liquid and gas) and on a model NC treatment permitting to correlate them with the spectra of cyclopropane and acetonitrile.
