Reaction Conditions

Reaction Steps

Into a 2 liter reaction flask equipped with heating mantle, stirrer, Bidwell water trap, reflux condenser, thermometer and nitrogen blanket apparatus is placed 1,000 ml (8.4 moles) of diethyl carbonate, and 25 grams (0.45 moles) of sodium methoxide. The resulting mixture is heated to 85° C. While maintaining the reaction mass at 85°-86° C. over a period of 1 hour, 695 grams (4.5 moles) of a composition containing a major proportion of 4-cyclooctenyl formate having the structure: ##STR78## and a minor proportion of bicyclooctanyl formate having the structure: ##STR79## produced according to Example I, is added while removing ethyl formate reaction product from the reaction mass using the Bidwell trap. At the end of the 1 hour period, the reaction mass is stirred at a temperature of 85°-86° C. for an additional 1 hour.
