Application In Synthesis of 3-HydroxybenzaldehydeIn 2019 ,ãFe3O4@nano-cellulose/Cu(II): a bio-based and magnetically recoverable nano-catalyst for the synthesis of 4H-pyrimido[2,1-b]benzothiazole derivativesã?appeared in RSC Advances. The author of the article were Safajoo, Nasrin; Mirjalili, Bi Bi Fatemah; Bamoniri, Abdolhamid. The article conveys some information:
Fe3O4@nano-cellulose/Cu(II) as a green bio-based magnetic catalyst was prepared through in situ co-precipitation of Fe2+ and Fe3+ ions in an aqueous suspension of nano-cellulose. The mentioned magnetically heterogeneous catalyst was characterized by FT-IR, XRD, VSM, FESEM, TEM, XRF, EDS and TGA. In this research, the synthesis of 4H-pyrimido[2,1-b]benzothiazole derivatives I (R = 4-Cl, 2-NO2, 3,4-(OH)2, etc.) was developed via a three component reaction of aromatic aldehydes RC6H4CHO, 2-aminobenzothiazole and Et acetoacetate using Fe3O4@nano-cellulose/Cu(II) under solvent-free condition at 80 °C. Some advantages of this protocol are good yields, environmentally benign, easy work-up and moderate reusability of the catalyst. After reading the article, we found that the author used 3-Hydroxybenzaldehyde(cas: 100-83-4Application In Synthesis of 3-Hydroxybenzaldehyde)
3-Hydroxybenzaldehyde(cas: 100-83-4) is used as an ionophore, during the development of an highly selective and sensitive PVC membrane sensor, which can be used as a Tb3+ ion selective electrode.Application In Synthesis of 3-Hydroxybenzaldehyde
