Reference of 652-12-0, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 652-12-0, Name is Tetrafluorophthalic anhydride,introducing its new discovery.
Process for the preparation of tetrafluorophthalic acid and/or tetrafluorophthalic anhydride
The present invention relates to a process for the preparation of tetrafluorophthalic acid and/or tetrafluorophthalic anhydride by reacting a compound of the formula STR1 in which X is a radical STR2 which is optionally mono- or polysubstituted on the aromatic nucleus by fluorine and/or chlorine and/or alkyl groups having 1 to 4 carbon atoms, or is a radical STR3 in which R1, R2 and R3 are as defined, with water, and subsequently removing the water still present by azeotropic distillation or extracting the tetrafluorophthalic acid and/or its anhydride with a water-insoluble solvent or solvent mixture.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 652-12-0, and how the biochemistry of the body works.Reference of 652-12-0
