It is prepared by condensation of chloranil and 3-amino-N-ethylcarbazole. It has a centrosymmetric angular structure. [ 2 ] For many years, the structure was assigned, incorrectly, as having a "linear structure" ( EC no. 228-767-9, CAS RN 6358-30-1) which differ in terms of the carbazole ring fusion .
Bucherer carbazole synthesis. A third method for the synthesis of carbazole is the Graebe–Ullmann reaction. Graebe–Ullmann reaction. In the first step, an N-phenyl-1,2-diaminobenzene (N-phenyl-o-phenylenediamine) is converted into a diazonium salt which instantaneously forms a 1,2,3-triazole. The triazole is unstable and at elevated ...
Melting point: 66 °C (151 °F; 339 K) ... N-Vinylcarbazole is an organic compound used as a monomer in the ... It is produced by the vinylation of carbazole with ...
Chiyoda (Japan) uses MCH-TOL as the hydrogen carrier for its SPERA hydrogen delivery business. [16] According to reports for Chiyoda's demonstration plant, which has a production rate of 50 Nm 3 per hour, the dehydrogenation of MCH happens at 350 °C and with a Pt/Al 2 O 3 catalyst, with an MCH conversion rate greater than 95% and toluene ...
3-Amino-9-ethylcarbazole (AEC) is a chemical compound commonly used as a chromogenic substrate in immunohistochemistry, specifically for visualizing sections stained with HRP-conjugated secondary antibodies. [1]
Polyvinylcarbazole was discovered by the chemists Walter Reppe (1892-1969), Ernst Keyssner and Eugen Dorrer and patented by I.G. Farben in the USA in 1937. [4] [1] PVK was the first polymer whose photoconductivity was known.
Hantzsch ester refers to an organic compound with the formula HN(MeC=C(CO 2 Et)) 2 CH 2 where Me = methyl (CH 3) and Et = ethyl (C 2 H 5). It is a light yellow solid. The compound is an example of a 1,4-dihydropyridine. It is named after Arthur Rudolf Hantzsch who described its synthesis in 1881.
N-Ethyl-N-(2-chloroethyl)aniline is the organic compound with the formula C 6 H 5 N(Et)(CH 2 CH 2 Cl) (Et = ethyl). It is a low-melting colorless solid that is an alkylating agent . The compound is a precursor to several cationic azo dyes via reaction of the chloroethyl group with tertiary amines or pyridine followed by azo coupling .
