Determination of dichloroanilines in human urine by GC-MS, GC
WebObjective: In order to develop a screening test to detect human occupational exposure to aromatic amines such as 3,4-dichloroaniline (3,4-DCA) and 3,5-dichloroaniline (3,5-DCA), we first investigated the urinary excretion of these highly toxic compounds in the rat. The study was performed after both oral and dermal application, even though contact … WebDiazotization in Acetic Acid. [1 19] Acetic acid (4 mL) was added to a beaker containing 1.45 g (89.5 mmol) of 2,5-dichloroaniline. The reaction mixture was chilled in an ice bath to 12°C and sodium nitrite (0.81 g, 1 1 .74 mmol, 1 .07 equivalents) in 4 mL water was … easy bake recipes from scratch
