12/1/2020 · Abstract. A novel method was developed for the sensitive and visual detection of p-phenylenediamine (PPD) via immobilizing the target specie PPD on dialdehyde cellulose membrane (DCM) followed by the reaction with salicylaldehyde. The obtained solid fluorescent membrane (S-PPD-DCM) emitted yellow fluorescence under 365 nm UV light.
The relatively high sensitization potential of p-phenylenediamine was also demon-strated in an experiment with man. In a “repeated insult patch test” 24 volunteers were pre-treated with p-phenylenediamine 9 times in the course of 3 weeks. In the provocation, see more details brought about by p-phenylenediamine. The experiments here described were designed to test this question of causation. Several groups of guineapigs guineapigs Subject Category: Organism Names see more details were given subcutaneous injections of the distilled chemical or of the hydrochloride or the oxidized form.
We claim: 1. A method for preparing an acid salt of a p-phenylenediamine-type free base color developer comprising: a. dissolving a purified p-phenylenediamine free base in a solvent wherein said free base is prepared by the process of subjecting a solution containing said free base color developer to short path distillation having a temperature less than about 250° C.

p-phenylenediamine as monomer in 0,1 M of hydrochloride acid. The second procedure consists on mixing a 0,01g of p-phenylenediamine dissolved in acetonitrile with 1g of graphite and an appropriate quantity of Nujol. Thereafter, the electrode was prepared as described in section 2.2 and immersed in the 0, 1 M of aqueous chloride solution free …
