Appearance: Colorless to yellow liquid ; Assay：99%min by GC ; IR Identity: conform to standard ; HNMR： conform to standard ; carbon spectrum: conform to standard ; Water by K. F.:0.5% max or as per the customer’s request ; Loss on drying:0.5% max. or as per the customer’s request ; ================================================================================= Usage： 1. Pharmaceutical industry: used as pharmaceutical raw materials or intermediates 2. Dye intermediates: Their hydrochloride and sulfate salts can be used as color photographic developers 3. Research reagents: widely used in research fields such as molecular biology and pharmacology ============================================================================== Synthetic route Starting from N, N-diethylaniline, the product is obtained through a two-step reaction of nitrosation and reduction Nitrosation reaction Dissolve N, N-diethylaniline in hydrochloric acid aqueous solution and cool to 0-5 ° C. Slowly add sodium nitrite solution and perform electrophilic substitution reaction to generate p-nitroso-N, N-diethylaniline. After the reaction is complete, salt precipitation is carried out with salt, and the nitroso product is obtained by filtration. Restoration and Neutrality Add the nitroso product to an aqueous system containing iron powder and hydrochloric acid, and reduce it to an amino compound at 20-25 ° C. Add sodium carbonate for neutralization, then adjust the pH with liquid alkali to precipitate the product. After extraction, stratification, and vacuum distillation (120-150 ° C, 8 kPa), N, N-diethyl p-phenylenediamine (93-05-0) was obtained Uses : the pharmaceutical industry and dye intermediates, and their hydrochloride and sulfate salts can be used as color photographic developers Synonyms : P-AMINO-N,N-DIETHYLANILINE;P-AMINODIETHYLANILINE;N,N-DIETHYL-1,4-BENZENEDIAMINE;N,N-DIETHYL-1,4-PHENYLENEDIAMINE;N,N-DIETHYL-PHENYLENEDIAMINE;N,N-DIETHYL-P-PHENYLENEDIAMINE;N,N-DIETHYL-P-PHENYLENEDIAMINEE;4-(Diethylamino)aniline;N,N-diethylbenzene-1,4-diamine;N,N-diethylbenzene-1,2-diamine;2,3-diethylbenzene-1,4-diamine; Molecular Structure :
