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.

What are the by-product of saponification of fats and oils?
glycerin is the by-product
What is products of the saponification of NaOH?
Saponification is the hydrolysis of fat in presence of caustic soda (NaOH), the products are Soap and Glycerin CH2-CO-R1 CH2-OH R1-COONa | | CH-CO-R2 + 3NaOH --------> CH-OH + R2-COONa | | CH2-CO-R3 CH2-OH R3-COONa (Fat) (Glycerin) (Soap)
What is soap made of?
True soap is the result of a chemical reaction (saponification) of vegetable and/or animal fats with sodium hydroxide (lye) and it retains its natural glycerin. Most commercial "soap" is actually detergent and legally cannot be labeled as soap (for example, beauty bars). They remove the natural glycerin and sell it as a separate product.
Why refluxing is done in 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.
Is vaseline and glycerine the same?
No. Beewax is a '45 carbon-long chain' mono-ester that is a waxy solid (C15H31COOC30H61 melting point about 60oC) Glycerin is a 'three carbon-short chain' poly-alcohol viscous lquid (glycerol, C3H5(OH)3, propane-1,2,3-triol) The common link is you can use beewax in soap by itself and by the process of "saponification" which breaks the ester down into its component long-chain carboxylic salt (aka Soap) and medium-chain alcohol (which is glycerin if you use beef tallow but something different with saponified beeswax). If you look at saponification link, you'll see the general saponification reaction is R - CO - O - R' + NaOH --> R - CO - ONa (soap) + R' - OH (alcohol). Normally when fatty acid esters (from beef fat aka tallow, etc.) are saponified, you get conventional soap and glycerin. When you saponify beeswax instead of tallow you get a soap and an alcohol that is different from glycerin but is an "analog" of it.
What are the by-product of saponification of fats and oils?
glycerin is the by-product
Between butter and margarine which one got higher saponification value?
margarine has saponification value more then butter
What is products of the saponification of NaOH?
Saponification is the hydrolysis of fat in presence of caustic soda (NaOH), the products are Soap and Glycerin CH2-CO-R1 CH2-OH R1-COONa | | CH-CO-R2 + 3NaOH --------> CH-OH + R2-COONa | | CH2-CO-R3 CH2-OH R3-COONa (Fat) (Glycerin) (Soap)
What the saponification value of ocimum basilicum oil?
This value is between 4 and 10.
What is the saponification value of mentha arvensis essential oils?
Saponification value, or SAP value, is an approximated "value" assigned to the fats and oils used in soap making. Because essential oils contain no lipids, they will not saponify. Consequently, they have no SAP value.
What is the saponification value of castor oil?
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
Temperature related to saponification value?
Heat the flask on a steam bath.
Substance made when alkalis react with oils?
The process is called saponification, with which you make soap.

Why do you think ethanol is used in saponification process?
Ethanol is added to hasten saponification.

How is soap manafactured using sodium hydroxide?
Soap is manufactured in this way using a process called saponification of fats. Fats fall into a category of compounds called esters, molecules formed from an alcohol and a carboxylic acid. In the case of a fat the alcohol is glycerin (glycerol) and the acid is a fatty acid. Here is the generic, two-step equation for the saponification of an ester with a hydroxide (R represents the rest of each acid and ester). OH- + RO2-OR --> RO2H + RO- The ester is split into the corresponding acid and alkoxide ("salt" of an alcohol). RO- + RO2H --> ROH + RO2- Since ethoxides are highly basic they are quickly neutralized by the fatty acid. Resulting in the corresponding alcohol (glycerin) and fatter acid salt (the soap). The glycerin is then separated out.
