3-Hydroxythiophene-2-carboxylic acid (CAS# 5118-07-0)
| Iimpawu ezinobungozi | Xi – Irritant |
Intshayelelo
I-Acid yinto ephilayo ene-chemical formula ye-C6H5O3S, eyenziwa ngokudibanisa iqela le-carboxylic acid kunye neqela le-hydroxyl kwindawo ye-2 yendandatho ye-thiophene. Oku kulandelayo yinkcazo yendalo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwe-polymer acid:
Indalo:
-Inkangeleko: iasidi yinto eqinileyo emhlophe ukuya koluthubi.
-I-Solubility: Inokuchithwa emanzini kunye nezinye i-solvents eziphilayo (ezifana ne-alcohols kunye ne-ketones).
-Indawo yokunyibilika: Indawo yayo yokunyibilika imalunga ne-235-239°C.
Sebenzisa:
-I-Chemical synthesis: i-asidi ingasetyenziselwa njengento ephakathi kwi-synthesis yezinye izinto eziphilayo, ezifana nokulungiselela i-thiophene compounds, idayi kunye ne-pharmaceutical intermediates.
-Izinto zenzululwazi: Iipolymers ezenziwe ngeasidi zingasetyenziselwa ukulungiselela iiseli zelanga zelanga ezibhityileyo zefilimu kunye ne-organic field-effect transistors kunye nezinye izixhobo.
Indlela yokulungiselela:
Kukho iindlela ezininzi zokulungiselela i-calcium acid. Enye indlela esetyenziswa ngokuqhelekileyo kukusabela kwi-3-hydroxythiophene kunye ne-acid hydrogen compound efanelekileyo (njenge-acid chloride compound).
Ulwazi ngoKhuseleko:
-ayikho i-asidi ayinayo ityhefu ebonakalayo kunye nemiphumo emibi echazwe phantsi kweemeko eziqhelekileyo zokusetyenziswa.
-Ngenxa yokuba uvakalelo lomntu ngamnye kwiikhemikhali luhlukile, ukusetyenziswa kufuneka kulandele iinkqubo zokhuseleko, njengokugqoka iiglavu zokukhusela, iiglasi kunye neempahla zebhu, ukuphepha ukudibanisa nesikhumba okanye emehlweni.
-Xa ugcina, gcina iasidi kwindawo eyomileyo nengena umoya, kude nemithombo yobushushu kunye nezinto ezinokutsha.
Nceda uqaphele ukuba ezi nkcukacha zingentla zenzelwe ireferensi kuphela. Nceda ulumke xa usebenzisa okanye uphethe iasidi, kwaye ubhekisele kuncwadi oluthembekileyo lwemichiza ukuze ufumane inkcazelo engakumbi nechane ngakumbi.
