jackets ensure the circulation of a coolant fl fluid which is intended for heating or

for cooling the reactor.

￿ A heat exchanger: It allows to heat or to cool the coolant fluid circulating

through the reactor jacket. Heating is carried out by three electrical resistances
controlled by a dimmer for varying the heating power. It is intended to achieve
the required reaction temperature of the esteri

fl

cation. Cooling is provided by
circulating cold water through the heat exchanger. It is used to cool the reactor
when the reaction is completed.

A condenser: It allows to condense the steam generated during the reaction. It
plays an important role because it is also used to indicate the end of the reaction
which can be deduced when no more water is dripping out of the condenser.
