2-propoxyethyl chloroformate synthesis

1synthesis methods
-

Yield:90512-12-2 98.5 %Chromat.

Reaction Conditions:

in toluene at -5 - 5;Temperature;

Steps:

1.1.3 Preparation of 2-propoxyethyl chloroformate (CEP-1 )

Experiment number CEP-16: first put 2000g toluene, , the phosgene was absorbed at -5 ~ 0 degree C first, then the temperature was changed from 0 to 5 degrees C and 1000gCEP-0 was added to the photochemical reaction. The reaction temperature was controlled from 0 to 5 degrees C by dropping process. After the drip was finished, the temperature was kept from 0 to 5 degrees C, and the reaction was controlled to CEP-0 The content of CEP-1 was 98.5% by gas chromatography,the total amount of low boiling impurities is 0.7%.
