Abstract
N, N-ethylene higher alkyl urethanes were prepared by the reaction of higher alkyl chloroformates and an aqueous solution of ethyleneimine using sodium or ammonium carbonate as dehydrochloric acid agent, in the presence of a small quantity of non-ionic surface active agent under cooling and stirring. N, N-ethylene higher alkyl urethanes prepared in water as dispersion were separated and identified respectively.
N, N-ethylene stearyl urethane prepared in water was submitted to the finishing test on rayon fabric, with or without an urea-melamine-formaldehyde resin. The fabric after finishing possessed a durable and washable water-repellency.
