Cosa (chi) è saponification$72029$ - definizione

NUMBER OF MILLIGRAMS OF POTASSIUM HYDROXIDE REQUIRED TO SAPONIFY 1G OF FAT UNDER THE CONDITIONS SPECIFIED
Unsaponifiable; Saponification number; Unsaponifiables; Unsaponifiable matter
  • Example of [[saponification]] reaction of a [[triglyceride]] molecule (left) with potassium hydroxide (KOH) yielding [[glycerol]] (purple) and salts of fatty acids ([[soap]]).

Saponification value         
Saponification value or saponification number (SV or SN) represents the number of milligrams of potassium hydroxide (KOH) or sodium hydroxide (NaOH) required to saponify one gram of fat under the conditions specified. It is a measure of the average molecular weight (or chain length) of all the fatty acids present in the sample as triglycerides.

Saponification value

Saponification value or saponification number (SV or SN) represents the number of milligrams of potassium hydroxide (KOH) or sodium hydroxide (NaOH) required to saponify one gram of fat under the conditions specified. It is a measure of the average molecular weight (or chain length) of all the fatty acids present in the sample in form of triglycerides. The higher the saponification value, the lower the fatty acids average length, the lighter the mean molecular weight of triglycerides and vice versa. Practically, fats or oils with high saponification value (such as coconut and palm oil) are more suitable for soap making.
