Phthalic anhydride for industrial use — Methods of test — Part 9: Determination of impurities oxidiz...
This method is not specific for maleic anhydride. The polarographic method specified in part 7 should be used. The principle is based on the oxidation of unsaturated organic acids and anhydrides in a test portion with an excess of cold standard volumetric potassium permanganate solution in the presence of sulphuric acid, followed by iodometric determination of the potassium permanganate remaining…
Phthalate esters for industrial use — Methods of test — Part 4: Determination of acidity to phenolph...
The principle consists in titration of the acidity in a test portion, in ethanolic medium, with standard volumetric sodium hydroxide solution using phenolphthalein as indicator. - ISO 1385, Part 1 to Part 5 replace ISO Recommendation R 1385-1970.
Phthalate esters for industrial use — Methods of test — Part 5: Determination of ester content — Tit...
The principle consists in the saponification of ester in a test portion, using a measured excess of potassium hydroxide ethanolic solution, followed by back-titration with standard volumetric hydrochloric acid solution in the presence of phenolphthalein as indicator. - ISO 1385, Part 1 to Part 5 replace ISO Recommendation R 1385-1970
