Intshayelelo
I-Acid (i-asidi) yi-organic compound. Oku kulandelayo yintshayelelo kubume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:
Indalo:
-Ukubonakala: Ifom eqhelekileyo imhlophe ukuya kwi-crystal powder emhlophe.
-Indawo yokunyibilika: Indawo enyibilikayo yekhompawundi ngokuqhelekileyo iphakathi kwe-100-105 ° C.
-I-Solubility: Ine-solubility efanelekileyo kwezinye izinyibilikisi ze-polar, ezifana ne-ethanol, i-dimethyl sulfoxide, njl. Kodwa ukunyibilika kwamanzi kuphantsi.
Sebenzisa:
-asidi yindawo ephakathi esetyenziswa ngokuqhelekileyo kwintsimi ye-organic synthesis. Ingasetyenziselwa ukudibanisa iintlobo ezahlukeneyo zepyrazole okanye i-pyrimidine compounds.
-Le khompawundi inokusetyenziswa kwakhona njengento ekrwada kwintsimi yamayeza.
Indlela yokulungiselela:
-Ukulungiswa kwe-asidi kunokufezekiswa ngokuphendula kwamanyathelo amaninzi. Indlela eqhelekileyo yokwenziwa kukuqala kwinto yepyrazole kwaye ekugqibeleni udibanise imveliso ekujoliswe kuyo ngothotho lweempendulo zemichiza.
-Indlela yokulungiselela ethile inokwahluka ngokuxhomekeke kwinjongo yophononongo, ukufumaneka kwedatha, njl. njl., kwaye ungabhekisa kuncwadi olufanelekileyo lwenzululwazi okanye lwelungelo elilodwa lomenzi wechiza ngolwazi oluthe kratya.
Ulwazi ngoKhuseleko:
-i-asidi ngokuqhelekileyo i-compound ezinzile phantsi kokusetyenziswa ngokuchanekileyo kunye nokugcinwa. Nangona kunjalo, njengayo nayiphi na imichiza, isafuna ukuphathwa ngononophelo.
-Inokukhathazeka, ngoko kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa nesikhumba, amehlo okanye umgudu wokuphefumula.
-Xa usebenzisa kunye nokuphatha, landela iinkqubo zebhubhoratri ezichanekileyo kunye namanyathelo okukhusela umntu, kwaye uqinisekise iimeko ezifanelekileyo zokungenisa umoya.
