N-1-NAPHTHYLETHYLENEDIAMINE DIHYDROCHLORIDE MONOMETHANOLATE - Reference Information

EPA chemical substance information information provided by: ofmpeb.epa.gov (external link)
trait white to yellowish brown or gray crystalline solid or off-white powder.
naphthyl ethylenediamine hydrochloride colorimetric method naphthyl ethylenediamine hydrochloride colorimetric method is also called "Saltzman method". Solution absorption chemical method for the Colorimetric Determination of nitrogen oxides (NOx) after collection. The nitrogen oxides in the atmosphere are oxidized into NO2 through a Chromium Trioxide Oxidation tube, and then absorbed in solution to generate nitrous acid, and then the nitrogenation reaction with sulfanilic acid is carried out, and then the azo compound of Rose Red is generated by coupling with naphthalene ethylenediamine hydrochloride, according to the shade of color, colorimetric quantitative.
Storage Conditions keep the receptacle sealed and stored in a cool, dry place, ensure that the workshop has good ventilation or exhaust.
purpose reagent for determination of sulfonamides
Environmental protection reagent, hydrochloric acid naphthalene ethylenediamine colorimetric method for the determination of nitrogen oxides and other aniline in the atmosphere, as well as the determination of sulfonamides and nitrite, but also the Spectral determination of aminophenol, phenylenediamine, dinitroaniline, chloro aniline compounds, thiols and sulfonamides, etc.
for determination of folic acid, potassium, nitrite and sulfate; For spectrophotometric detection of aminophenol, phenylenediamine, dinitroaniline, chloroaniline, mercaptan and sulfanilamide
production method 1.? Will alpha? -Bromonaphthalene and ethylenediamine are reacted by heating under pressure, and then hydrochloric acid is added to the produced N-1-naphthyl ethylenediamine to form a salt, and crystals are precipitated.
