Saponification (grease), английский
Process in which a fat or some other compound of an acid and an alcohol reacts with an alkali to form a soap and glycerin or other alcohol.
Saponification number, английский
- The number of milligrams of potassium hydroxide (koh) that combine with one gram of oil under conditions specified by test method astm d 94. saponification number is an indication of the amount of fatty saponifiable material in compounded oil. caution must be used in interpreting test results if certain substances - such as sulfur compounds or halogens - are present in the oil, since these also react with koh, thereby increasing the apparent saponification number.
- (astm d-94) the number of milligrams of potassium hydroxide required to saponify the fats and/or esters in a one-g sample of a given material.

- A double decomposition reaction involving the addition of the elements of water and the formation of an acid and a base, an acid and an alcohol, or an acid and phenol.
- Chemical process where a mineral reacts with water.
Neutralization, английский
- Utilizing a lensometer to determine the dioptric power of an ophthalmic lens.
- Нейтрализация
- N нейтрали- зация
- [1] heavy gunfire to immobilize enemy activity in the area bombarded. [2] to render a mine incapable of firing, even though it may remain dangerous to handle.
