Standard Test Methods for Chemical Analysis of Soaps Containing Synthetic Detergents — 10 стр.
Реферат

These test methods detail the standard procedures for the chemical analysis of soaps containing synthetic detergents. The analytical procedures include the determination of the following chemical properties and substances: moisture and other matter volatile at a specified temperature; free alkali or free acid; anhydrous, salt-free soda soap; alcohol-soluble matter; matter insoluble in water; total alkalinity of matter insoluble in alcohol (alkaline salts); sodium silicate; phosphates; phosphates by colorimetric method using molybdenum blue); unsaponified and unsaponifiable matter; free fatty matter; chlorides in alcohol-soluble matter; rosin by McNicoll method; synthetic detergent by difference; and neutral inorganic salts.
