2,5-Thiophenedicarboxylic Acid

Incazelo emfushane:

I-adipic acid ne-thionyl chloride zixutshwe ngesilinganiso sesisindo esingu-1: (6-10) futhi zahlungwa kabusha amahora angama-20-60 phambi kwe-pyridine catalyst.I-solvent yahwamuka futhi insalela yashiswa ku-140-160 ℃ ku-3-7 H. I-Thiophene-2,5-dicarboxylic acid itholwe ngokwelashwa kwe-sodium hydroxide, imvula ye-asidi, i-filtration, i-decolorization kanye nokuhlanzwa.

Isicelo

I-ejenti emhlophe ye-fluorescent i-EBF ilungiswe ngokujiya komkhiqizo nge-o-aminophenol.Lesi sici esikhanyayo singasetshenziselwa inayiloni, i-polyester, i-polypropylene, i-chloro ne-triacetic acid fibers.Kungumkhiqizo onezakhiwo ezinhle kakhulu.Isetshenziswa kakhulu ekulungiseni i-agent emhlophe ekhanyayo, ikakhulukazi esetshenziselwa ukwenziwa mhlophe kwefayibha yokwenziwa, i-EVA, i-PVC, ipulasitiki nenjoloba, futhi ingasetshenziswa ekwenzeni mhlophe kwefilimu yepulasitiki, izinto zokubumba zokucindezelwa, izinto zokubumba umjovo, njll.
