NCPs can function as fluorescent probes to detect 2,4,6-trinitrophenol in aqueous media with extremely high sensitivity, low detection limit and good anti-photobleaching properties. The value of quenching constants (Ksv) is by up to 1.72 x 10(7) M-1 and the detection limit is as low as ...
I'm researching the synthesis of picric acid (2,4,6-trinitrophenol), and while I found several recipes and some explanations, some questions still bug me. The best procedure I found (subjectively speaking) is the disulfonation of phenol followed by nitration. My questions are: ...
Phenol, any of a family of organic compounds characterized by a hydroxyl group attached to a carbon atom that is part of an aromatic ring. Besides serving as the generic name for the entire family, the term phenol is also the specific name for its simple
6.The positive photoresist composition according to claim 2, wherein the novolac phenol resin (B) is obtained by performing polycondensation of 2,5-xylenol and 4-hydroxybenzaldehyde in the presence of an acid catalyst to obtain a polycondensate represented by formula (2-1) below:and then allowin...
The article discusses a study about the synthesis and crystal structure of the organic compound 4-(4-chlorophenyl)-1-[3-(4-fluorobenzoyl)propyl]-4-hydroxypiperidin-1-ium 2,4,6-trinitrophenolate. According to the authors, the piperidium ring exhibits a less distorted chair conformation. They ...
The azirine 1 reacts with the more acidic 2,4,6-trinitrophenol (picric acid) to yield 3,3,6,6-tetramethylpiperazine-2,5-bis( N , N -dimethyliminium) dipicrate ( 21 , Scheme 4 ). The methacrylamidinium salt 22 is the only product (97% yield) in the reaction of 8-hydroxy-5,7...
The invention belongs to the field of explosive processing, in particular to a DPLG (dinitro-diazophenol) burster and a preparation method thereof. The burster is composed of a mixture of 3,5-dimethyl ureido-2,4,6 trinitrophenol combined lead nitrate and an oxidizing agent; and the weight ...
The adsorbing properties of the synthesized hybrid organo-inorganic nanoparticles in relation to aromatic guest molecules (2,4,6trinitrophenol, 2,4-dinitrophenol, 2-nitroaniline, 3-nitroaniline, 4-nitroaniline, 2,4-dinitroaniline) were studied in comparison with unmodified silicon dioxide particles....
pi packing to form 2D layer structures. Both the two complexes show highly selective detection of 2,4,6-trinitrophenol, 2,4-dinitrophenol, 4-nitrophenol and 2-nitrophenol from benzene based nitroaromatics (NACs), and efficient removal of Congo Red (CR) from aqueous solution....
