WebOPD is an abbreviation for Overfilling Prevention Device, which is part of national fire and safety standards designed to make the use of propane even safer. An OPD is a safety … o-Phenylenediamine (OPD) is an organic compound with the formula C6H4(NH2)2. This aromatic diamine is an important precursor to many heterocyclic compounds. It is isomeric with m-phenylenediamine and p-phenylenediamine. Ver mais Commonly, 2-nitrochlorobenzene is treated with ammonia and the resulting 2-nitroaniline, whose nitro group is then reduced: ClC6H4NO2 + 2 NH3 → H2NC6H4NO2 + NH4Cl Ver mais o-Phenylenediamine condenses with ketones and aldehydes to give rise to a variety of useful products. Its reactions with Ver mais With an LD50 of 44 mg/L (in water), o-phenylenediamine is about 1000 times less toxic than the para-isomer. Anilines are typically handled as if they are carcinogenic. For many applications, OPD has been replaced by safer alternatives such as Ver mais WebOne OPD tablet and one urea hydrogen peroxide/buffer tablet, dissolved in 20 ml of water, provides 20 ml of ready-to-use substrate. When the tablet is dissolved in this manner, the final concentrations will be 0.4 mg/ml OPD, 0.4 mg/ml urea hydrogen peroxide, and 0.05 M phosphate-citrate, pH 5.0. Tablets are individually packaged in foil packets. fishingprince plays with array
