| introduction | p-dimethylaminobenzaldehyde is an organic intermediate, which can be prepared from N,N-dimethylaniline and DMF. It is reported in the literature that p-dimethylaminobenzaldehyde can be used to prepare high-purity DAST source powder, and can also be used to make a color solution to analyze amino hydroxyurea. |
| applicazione | 1. dye intermediates and analytical reagents. The product is used for the determination of indole, skatole, urine blue mother, tryptophan and ergot alkali, etc., and is also used to distinguish serum rash and scarlet fever. 2. In terms of dyes, it can be used to synthesize pressure-sensitive dyes. It is also used in the production of cationic brilliant red G(C.I.BasicRed52). It can also be used as a dye intermediate; used as a reagent for the determination of urobilin, indole, alkaloids, etc. and a chromatographic analysis reagent. 3. Determination of indole, skatole, urine blue mother, tryptophan, albumin, hydrogen peroxide, arsine sodium, o-aminobenzoic acid, antipyrine ergot, etc. It is also used to distinguish serum rash and red fever. 4. Make dyes. 5. Reagents used to detect amino acids, peptides, amines, indole, hydrazine, hydrogen peroxide, anthranilic acid, antipyrine and ergot alkali; used as a chromogenic agent for tryptophan; used to detect tryptophan in protein; used to identify indole-producing microorganisms Test reagents; can react with pyrrole and primary amine to form colored condensation products (Schiff base). |
| preparation | in a 100ml three-mouth bottle, add 4.9g(0.032mol) of phosphorus oxychloride, slowly add 2.5g(0.031mol) of DMF in an ice bath, finish dropping (8min), stir for 10min, slowly add 3.66g(0.03mol) of N,N-dimethylaniline (10min) to the three-mouth bottle, and finish dropping, move the reaction solution to a boiling water bath for 2 hours. After the reaction, pour the reaction solution into 20ml of ice water, adjust the PH = 4 with 30% sodium hydroxide solution, stand for crystallization, filter the next day to obtain a light yellow or nearly colorless solid, and recrystallize with 30ml of ethanol-water (1:2.5V/V) to obtain the product p-dimethylaminobenzaldehyde. |

| metodo di produzione | using N,N-dimethylaniline as raw material, two methods can be used for production. (1) Methylene-N,N-dimethylaminobenzylamine is generated by the reaction of urotropine, and N,N-dimethylbenzyleneamine is generated by translocation, and then the product is hydrolyzed. (2) Reacts with dimethylformamide in the presence of phosphorus oxychloride. In addition, there is a laboratory preparation method that uses N,N-dimethylaniline, sodium nitrite, and formaldehyde as raw materials. |
| temperatura di combustione spontanea | 445°C |
