Yield:103-09-3 90.9%

Reaction Conditions:

with NKC-9 at 80; for 3 h;Catalytic behavior;Reagent/catalyst;Temperature;

Steps:


Transesterification reaction procedure: All the experiments were conducted in a 4-neck round bottom flask of volume250 mL equipped with a stirrer, a thermometer, a condenserpipe and a pressure-equalizing dropping funnel. The 4-neckround bottom flask was dipped in a constant temperature waterbath which was equipped with a temperature sensor. 2-Ethylhexanol and NKC-9 were put into the 4-neck round bottomflask. The temperature in the reactor was maintained within±1 °C with respect to the desired temperature. The measuredquantities of 2-ethylhexanol and NKC-9 were charged intothe 4-neck round bottom flask and methyl acetate was chargedto the constant pressure drop funnel. Once the desired temperature was achieved, the methyl acetate was being droppedinto the reactive mixture over a 2 h period. After the droppingwas finished, the temperature is maintained at the desiredtemperature for the fixed time. NKC-9 and the reactive liquidwere separated by vacuum filtration when it cooled down andthe NKC-9 was recycled at the same time. Finally the fractionbetween 130 and 140 °C was collected by reduced pressuredistillation and weighed this fraction.
