2-hydroxyethyl N-butylcarbamate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 274.8 grams of ethylene carbonate (3.12 moles) were placed in a round bottom flask equipped with stirrer, thermometer, addition funnel and reflux condenser. 228.2 grams (3.12 mole) of butylamine were charged to the addition funnel and added to the flask at a rate sufficient to maintain the flask contents at 50°-80° C. The resultant reaction product was allowed to stand overnight. Thereafter, stripping of the reaction product in a rotary evaporator gave 449.9 g of crude product. A portion of the crude product was distilled at a pressure of 2 mm Hg, and a temperature of from 124° C. to 126° C. to purify same. The HLB value of 2-hydroxyethyl 1 butyl carbamate calculated as previously described is 12.9. equipped with stirrer thermometer, addition funnel reflux condenser added to the flask at a rate sufficient to maintain the flask contents at 50°-80° C The resultant reaction product Thereafter, stripping of the reaction product in a rotary evaporator
