Pyrrole is a heterocyclic, aromatic, organic compound, a five-membered ring with the formula C 4 H 4 NH. [3] It is a colorless volatile liquid that darkens readily upon exposure to air. Substituted derivatives are also called pyrroles, e.g., N -methylpyrrole, C 4 H 4 NCH 3 .
Polypyrrole was used in the microwave fabrication of multiwalled carbon nanotubes, a rapid method to grow CNT's. [19] A water-resistant polyurethane sponge coated with a thin layer of polypyrrole absorbs 20 times its weight in oil and is reusable. [20] The wet-spun polypyrrole fibre can be prepared chemical polymerization pyrrole and DEHS as ...
DPP dyes are based on the bicyclic heterocyclic compound diketopyrrolopyrrole. 2,5-Dihydropyrrolo[3,4-c]pyrrole-1,4-dione is a basic body of Diketopyrrolopyrrole dye. DPP pigments are an important class of high-performance pigments used in inks, paints and plastic.
Tetrapyrroles are a class of chemical compounds that contain four pyrrole or pyrrole-like rings. The pyrrole/pyrrole derivatives are linked by (= (CH)-or -CH 2-units), in either a linear or a cyclic fashion. Pyrroles are a five-atom ring with four carbon atoms and one nitrogen atom.
Pyrrole-2-carboxylic acid is an organic compound with the formula HNC 4 H 3 CO 2 H. It is one of two monocarboxylic acids of pyrrole. It is a white solid. It arises in nature by dehydrogenation of the amino acid proline. [1] It also arises by carboxylation of pyrrole. [2] The ethyl ester of this acid is readily prepared from pyrrole. [3]
1. Tennis Ball. Tennis balls are so useful that you may want to buy some to keep around the house even if you don’t play. For example, half a tennis ball can help screw open tight caps.
Pyrrolidine is used as a building block in the synthesis of more complex organic compounds. It is used to activate ketones and aldehydes toward nucleophilic addition by formation of enamines (e.g. used in the Stork enamine alkylation ): [ 8 ]
