E.g. 1/10 mol. PMDA and 2/10 mol. o-phenylene diamine are intimately admixed and heated at 300 degrees C/3hrs. in an appts. which has been purged with N2. The pigment dyestuff so formed is ground finely and used directly for colouring the plastic material....
and subsequent ion-association withcrystal violet[757]formed the basis for the determination of ppb amounts by an extractive spectrofluorimetry. Of the few mixed ligand systems described for molybdenum[65–72], the one based on the use of bromopyrogallol red andethylviolet[66]is more sensitive ...
