Don't miss out—hit that play button now! 🎬🧼🔬 Conditions of saponification 1. Industrial soap-making The blended fats (e.g. beef tallow and coconut oil) are mixed with concentrated sodium hydroxide in large vats called 'kettles'. • Steam jets are used to heat the alkaline mixture. • Following saponification, hot brine is added to precipitate ('salt out') and wash the soap. The soap curd separates from the aqueous layer. Salting out precipitates ionic substances by greatly increasing the concentration of ions in the solution. • The aqueous layer is pumped out and processed to extract the glycerol, which is purified and used for many applications, including toiletries, cosmetics and pharmaceuticals. Water is added to the soap curd to remove salts and alkali. • The soap is vacuum-dried before processing into soap bars, flakes or powders. 2. Laboratory It is impossible to prepare soap by heating the fat/oil mixture with steam and removing the glycerol to increase the product yield in the school laboratory without considerable difficulty, so a one-step process is more appropriate. It is also easier to use oil, such as olive oil. A fat/oil mixture requires more heating, so oil is a safer saponification method. Nor is it possible to use very high temperatures or pressures in the school laboratory, so the mixture is boiled instead. Salt can be added after the boiled solution has cooled. A suitable method for the production of soap in a school laboratory is as follows: 1. Add 10mL of olive oil to a beaker with boiling chips (to prevent superheating). 2. Determine the stoichiometric amount of 6 mol L-1 sodium hydroxide solution to use (around 200-300mL) and add this with care (it is extremely corrosive) to the beaker over a heater–stirring hot plate with a magnetic stirrer. 3. Allow simmering until no more oil is visible. 4. Cool and add 50mL sodium chloride to the mixture. 5. Heat for 10-15 minutes. 6. Cool and filter through glass wool to remove any solid sodium hydroxide or chloride. 7. Take a sample of the soap and add to water to see if it foams when agitated. Safety issues Wear safety glasses and protective clothing, as sodium hydroxide is caustic. The soap contains some excess alkali and should not touch the skin. Boiling should be gentle to avoid spitting. Place a clock glass over the beaker to prevent this from happening.
