Synthetic Route of 14187-32-7, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6. In a patent, introducing its new discovery.
Solvent extraction separation of vanadium with dibenzo-18-crown-6
A novel method is described for the simultaneous extraction and direct spectrophotometric determination of vanadium with dibenzo-18-crown-6 from 1.0 mol dm-3 potasium thiocyanate containing 3.0 mol dm-3 hydrochloric acid solution.The effect of concentrations of hydrochloric acid, potassium thiocyanate, crown ethers and role of diluents has been studied.Vanadium has been separated from many mixtures, containing, lead, cadmium, chromium, thallium, cerium, thorium and yttrium which are generally associated in ores, alloys and in steel samples.The proposed method is simple, sensitive, rapid, selective and permits extractive separation and direct spectrophotometric determination in one single operation.
