��N.B. — The heats of formation marked with an asterisk (*) are those which have been directly derived from the heats of combustion.
��Organic Acid Esters. — Their heat of combustion is generally a little higher than the sum of the heats of com- bustion of the alcohol and of the acid. The reaction
acid -h alcohol = ester + water
is slightly endothermic. It is also generally slow and incomplete.
The following tables are important from a physiological point of view.
