3-Hydroxythiophene-2-carboxylic acid (CAS# 5118-07-0)
| Izimpawu Eziyingozi | Xi - Irritant |
Isingeniso
I-Acid iyinto ephilayo enefomula yamakhemikhali ye-C6H5O3S, eyakhiwe ngokuxhuma iqembu le-carboxylic acid kanye neqembu le-hydroxyl endaweni yesi-2 yendandatho ye-thiophene. Okulandelayo incazelo yemvelo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwe-polymer acid:
Imvelo:
-Ukubukeka: i-asidi iqinile emhlophe kuya kokuphuzi.
-Ukuncibilika: Kungancibilika emanzini nakwezinye izincibilikisi eziphilayo (ezifana notshwala nama-ketones).
-Indawo yokuncibilika: Indawo yayo yokuncibilika icishe ibe ngu-235-239°C.
Sebenzisa:
-I-Chemical synthesis: i-asidi ingasetshenziswa njengendawo ephakathi yokuhlanganiswa kwamanye ama-organic compounds, njengokulungiswa kwezinhlanganisela ze-thiophene, odayi kanye ne-intermediate yemithi.
Isayensi Yezinto Ezibalulekile: Ama-polymers ahlanganiswe nge-asidi angasetshenziswa ukulungisa amaseli elanga efilimu emincane emincane kanye nama-transistors we-organic field-effect namanye amadivaysi.
Indlela Yokulungiselela:
Kunezindlela eziningi zokwenza i-calcium acid. Enye indlela evame ukusetshenziswa ukusabela ku-3-hydroxythiophene ngenhlanganisela ye-asidi ye-hydrogen efanele (njengenhlanganisela ye-asidi chloride).
Ulwazi Lokuphepha:
-ayikho i-asidi ayinabo ubuthi obusobala kanye nemiphumela emibi ebikwe ngaphansi kwezimo ezijwayelekile zokusetshenziswa.
-Ngenxa yokuthi ukuzwela komuntu ngamunye kumakhemikhali kuhlukile, ukusetshenziswa kufanele kulandele izinqubo zokuphepha, njengokugqoka amagilavu okuzivikela, izibuko kanye nezingubo zaselabhu, ukugwema ukuthintana nesikhumba noma emehlweni.
-Lapho ugcina, gcina i-asidi endaweni eyomile nengena umoya, kude nemithombo yokushisa nezinto ezivuthayo.
Sicela uqaphele ukuthi imininingwane engenhla ingeyereferensi kuphela. Sicela uqaphe lapho usebenzisa noma uphatha i-asidi, futhi ubhekisele ezincwadini zamakhemikhali ezinokwethenjelwa ukuze uthole ukwaziswa okwengeziwe nokunembile.
