describe the manufacturing of soaps and detergents?
Answers
Answer:
Saponification of fats and oils is the most widely used soap-making process. This method involves heating fats and oils and reacting them with a liquid alkali to produce soap and water (neat soap) plus glycerine. The other major soap-making process is the neutralization of fatty acids with an alkali.
Manufacturing of Soaps and Detergents
Soaps are the sodium salts and potassium salts of higher fatty acids such as steric acid and palmitic acid, oleic acid .
Sodium salts of fatty acids are hard soaps which are used for making shaving creams and shampoos.
Soaps are formed by using vegetable oils containing triglyceride by a process called saponification .
Oil and fat containing triglyceride is heated with Sodium Hydroxide or potassium hydroxide.
The Soaps is then collected and placed in moulds.
Detergents are the sodium salts of benzene H2SO4.
These are formed by the reaction of aromatic Hydrocarbons with concentrated acids.
This Reaction give the corresponding sulfuric acid.
Soaps and detergents are commonly used for washing our hands and clothes.
