This value is between 4 and 10.
Saponification is not applied to pure stearic acid; stearic acid esters are used.
Thymol is a good catalyst in saponification. I personally used it during chem prac class :)
saponification
it is an endothermic
Saponification is the reaction between triesters and alcohol.Mineral oil is composed of paraffins and alkanes ,it does'nt contain ester group hence it does not undergo saponification
Saponification value is the amount of pure sodium hydroxide needed to saponified 100 grams of oil No. saponified castor oil is from 12.5 to 13 grams
ethanol allows oil to be able to mix with water.
Glycerin and soap are the bye-products of saponification. The saponification value of glycerine are values of the percentage of lye it takes to convert one unit of fat, oil or fatty acid into glycerin.
This value is between 4 and 10.
This is just like the saponification of fats which produces soap.
Ethanol is added to hasten saponification.
Saponification is the process of producing soap. Refluxing is done in saponification to distill and remove fat droplets in order to complete the process.
To make soap from scratch requires treating an oil or fat with an alkali, such as lye. Oregano is an additive that can be added to the soap after the saponification process is complete.
Insoluble soaps are not likely to exist, they won't work when not IN water. For more you can trust on this: his process is called saponification: fat + sodium hydroxide -> Sodium salts of fatty acid (Soap) + glycerol
because alcohol is required for dissolving both KOH and lipid
what happen when fatti acid react with the NaOH
