Название (англ.):
Acetic acid for industrial use; Methods of test; Part 4 : Determination of acetaldehyde monomer content; Titrimetric method
Описание (англ.):
The principle of the determination consists in reaction of the acetaldehyde present in a test portion with an excess of sodium hydrogen sulphite solution, and iodometric titration of the residual sodium hydrogen sulphite. The method is applicable to products having acetaldehyde monomer contents equal to or greater than 0,01 % (m/m). This International Standard as also been approved bythe International Union of Pure and Applied Chemistry (IUPAC).International Standards ISO 753/1 to ISO 753/11 cancel and replace ISO Recommendation R 753-1968.
