Nitrosation of m-xylene, anisole, 4-nitrophenyl phenylether and toluene in trifluoroacetic acid or in acetic–sulfuricacid mixtures under nitric oxidenitrosation, denitrosationChemInform is a weekly Abstracting Service, delivering concise information at a glance that was extracted from about 100 leading ...
A stainless-steel column packed with octadecyl silanized silica gel was used and the mobile phase was a mixed solution of methanol/water/acetic acid (20/80/0.2). The method is simple and specific. Urine can be analyzed directly, without solvent extraction or pretreatment. The method has a ...

of a lower fatty acid, e.g. acetic acid. The mixt. of I + II is very pure and has less colour and a lower content of fluorescent impurities. There is less corrosion of the plant, since fatty acid and halogen (cpds.) promoters are not present....
Satisfactory separation of these metabolites was obtained on TLC plates covered with silica gels and developed in chloroform acetic acid-water (4:1:1);p-dimethylaminobenzaldehyde in acetic acid anhydride was applied to develop the colour. The sensitivity of the method was 6 micrograms hippuric acid...
