5.5 ESTER VALUE

5.5 ESTER VALUE

 ​            The ester value is the number of mg of potassium hydroxide required to saponify the esters present in 1 g of the substance. If the Saponification Value and the Acid Value have been determined, the difference between these two represents the Ester Value.

 ​            Determine the “Acid Value” (Appendix 5.4) of the substance and the “Saponification Value” (Appendix 5.7). Calculate the ester value from the equation:

 ​            Ester Value = Saponification Value − Acid Value.
