PEK was prepared from p-phenoxybenzoic acid, using polyphosphoric acid (PPA)9 as solvent and catalyst (equation 1). (1) The polymer was reported to have a melting point (Tm) of 360 °C and to be insoluble in organic solvents, but, surprisingly, was described as ‘essentially amorphous’...
3,5-Dichloro-2,4-difluoronitrobenzene can be prepared by reaction of 2,3,4,5-tetrachloronitrobenzene with fluorides of the heavy alkali metals in dimethyl sulphoxide (DMSO) or a DMSO-containing mixture, if the reaction is carried out at a temperature of 60-160 DEG C and for a reaction...
m-Nitrophenol can be prepared bydiazotizing m-nitroaniline and subsequently heating with a large volume of water;1by treating benzene with mercury nitrate and nitric acid in an atmosphere of carbon dioxide;2and by boiling m-nitrophenetole (from phenacetin by nitration, hydrolysis, and diazotizati...

It is prepared by the reaction between m-dinitrobenzene and potassium fluoride. 3.3 Usage 1-Fluoro-3-nitrobenzene is a di-substitiuted benzene derivative used for the synthesis of fluoroaromatic compounds through fluorodenitration and other pharmaceuticals. 1-Fluoro-3-nitrobenzene Preparation Products...
, and these changes might be due to changes in the soil environment. First, the biochar treatment increased the relative abundances ofMassilia,Sphingomonas, andSymbiobacteraceae.Massiliamight indirectly participate in the degradation of nitrobenzene by participating in the degradation of the benzene ...
It is observed that the sizes of NZVI particles range from 10 to 30 nm, which is attributed mainly to the intensified micromixing using the high gravity technique. The composition of the as-prepared NZVI was examined by X-ray diffraction (XRD). As shown in Fig. 2b, the main peaks are ...
