What Does Sap Value Mean

SAP values are the numeric values that allow you to calculate the precise amount of sodium hydroxide (NaOH) or potassium hydroxide (KOH) required to fully saponify a given weight of oil/s. … i.e. 4lb (1816g) of oils and 8.2oz (233g) sodium hydroxide will require approximately 1lb 8oz (680g) of water.

How is SAP value calculated?

Saponification Value = (A – B) x N x 56.1 W This method is used to determine the total acid content, both free and combined, of tall oil. … The saponification value is therefore a measure of tall oil quality. It is determined by measuring the alkali required to saponify the combined acids and neutralize the free acids.
