In this reaction, the triglyceride units of fats react with sodium hydroxide or potassium hydroxide and are converted to soap and glycerol. Coconut oil has a higher saponification value. :26266-57-9. Such a determined constant of saponification value is then sought and marked on the left hand side of the vertical scale SV. Code to add this calci to your website. Saponification value is represented by the milligrams of potassium hydroxide it takes to saponify (turn into soap) one gram of fat. Making shampoo bars is a very different process from making body soap in a lot of ways. Fatty acids are simply carboxylic acids with very long chains so a general formula may be something like this (of course the fatty acid doesn't have to be saturated or could be branched):. According to 1 H, 13 C, and X-ray data, this compound is a true 3,4-dihydroxythiophene. Sap value= mg of KOH/ NaOH required to break ALL the TG in the oil.

Saponification value definition is - a measure of the total free and combined acids especially in a fat, wax, or resin expressed as the number of milligrams of potassium hydroxide required for the complete saponification of one gram of substance. The most important element when making lye soap is the SAP Value (saponification values) of your oil. In this reaction, the triglyceride units of fats react with sodium hydroxide or potassium hydroxide and are converted to soap and glycerol. The Ester Value is the number of mg of potassium hydroxide required to saponify the esters in 1. Saponification value (or "saponification number"/"Koettstorfer number", also referred to as "sap" for short)Since saponifiable components of the original oil mixture do form soaps, the result of a soap making procedure is a mixture of soaps and other. The soap molecule has two parts: a polar group (-COO-Na +) and a non-polar group (R-hydrocarbon part). Figure 1 : The oxidation of oil over time as measured by peroxide value (PV), anisidine value (AV) and Totox value. Learn the principle, procedure of Paper Chromatography along with its types and applications. The process requires the presence of a strong base (hence, as you correctly assert, KOH (potassium hydroxide) or NaOH (sodium hydroxide) : To my knowledge there is no reason why sodium carbonate will not work, although it might be possible to heat the hell out of it to drive off the CO2. Alsberg and Alonzo E. Weight of KOH = Normality of KOH * Equivalent weight* volume of KOH in litres.
