PREPARATION:A 2-phenoxyethyl halide shown by the formula II (Y is halogen) is reacted with a metahydroxybenzoic acid amide derivative shown by the formula III in the absence of a solvent or in an inert organic solvent such as toluene, xylene, etc. in the presence of a dehydrohalogenating...
PROCESS:A halomethylcyclohexane of formula II (X is halogen) and an m-hydroxybenzoic acid amide derivative of formula III are heated at 50 deg.C- the refluxing temperature in the absence or presence of an organic solvent, e.g. toluene, with a dehydrohalogenating agent, e.g. Na2CO3, to ...

acidSolid-phaseextractionMilkA simple, fast, precise and eco-friendly method, based on ion chromatography (IC) with a suppressed conductivity detector, was proposed for the determination of benzoic acid (BA) in milk in this paper. The chromatographic separation was accomplished by using an anion ...
