I-anhydride yeCitraconic yikhompawundi ekhethekileyo neguquguqukayo yendalo eneempawu ezahlukeneyo kunye nokusetyenziswa kwayo. Le kristale solid engenambala iyafumaneka kurhwebo kwaye inokwenziwa ngeendlela ezahlukeneyo.
I-anhydride ye-citraconic ikwiqela leekhompawundi ezaziwa ngokuba zii-anhydrides ezijikelezayo ezisetyenziswa kakhulu ekuqulunqweni kweekhemikhali, ukwenziwa kwe-polymerization, kunye nezinye iinkqubo zoshishino. Ikwasetyenziswa kakhulu ekuvelisweni kweeresini, ii-coating, iipeyinti kunye nee-adhesives.
Enye yezona mpawu zibalaseleyo ze-citraconic anhydride kukusebenza kwayo kwiinucleophiles ezahlukeneyo kunye nee-electrophiles, nto leyo eyenza ukuba ikwazi ukwenza ii-chemical reactions ezininzi. Umzekelo, ingasetyenziswa njengebhloko yokwakha ezinye ii-organic compounds ezifana ne-maleic anhydride, i-acridine kunye ne-pyridine derivatives. Ngaphezu koko, ingasetyenziswa njenge-arhente yokuguqula ii-polymers okanye ezinye ii-compounds ngeenjongo ezahlukeneyo ezifana nokuphucula iipropati zazo zomzimba, zeekhemikhali okanye zebhayoloji.
Enye yezona ndlela ziphambili zokusetyenziswa kwe-citraconic anhydride kukwicandelo lokwenziwa kwe-polymer. Ngenxa ye-reactivity yayo ephezulu, isetyenziswa kakhulu njenge-monomer okanye i-comonomer ekuveliseni iintlobo ezahlukeneyo ze-polymers ezifana nee-polyesters, ii-polyamides kunye nee-vinyl polymers. Izifundo zibonise ukuba ii-citraconic anhydride-modified polymers zibonisa iipropati eziphezulu ze-mechanical, thermal, kunye ne-biochemical xa kuthelekiswa nee-polymers ezingatshintshwanga. Oku kuyenza ibe yinto ekhangayo yokusetyenziswa kwizixhobo zonyango ezifana nee-implants, iinkqubo zokuhambisa amayeza kunye nee-scaffolds zobunjineli bezicubu.
Enye indlela enomdla yokusebenzisa i-citraconic anhydride kukuyinyibilikisa kwiindlela ezahlukeneyo zeekhemikhali. Oku kungenxa yeempawu zayo ezintle zokunyibilikisa, ezivumela ukuba inyibilikise iintlobo ngeentlobo zeekhompawundi ze-organic kunye ne-inorganic. Ezinye izifundo zikwabonise ukuba ineempawu zokulwa neentsholongwane kunye ne-fungus, nto leyo eyenza ukuba ibe luncedo ekwenzeni izibulali-ntsholongwane kunye neengubo ze-antimicrobial.
I-anhydride ye-citraconic ikwasetyenziswa kwicandelo lokwenziwa kwezinto eziphilayo. Ingasetyenziswa njenge-reactant okanye izinto zokuqala ukulungiselela iikhompawundi ezahlukeneyo zezinto eziphilayo ezifana nee-organic acids, ii-carboxylates, ii-amides, ii-ketones, kunye nee-aldehydes. I-reactivity ephezulu ye-citraconic anhydride eneentlobo ngeentlobo zee-nucleophiles kunye nee-electrophiles yenza ukuba ibe ngumviwa ofanelekileyo wokwenziwa kwee-molecules zezinto eziphilayo ezintsonkothileyo.
Okokugqibela, i-citraconic anhydride ingasetyenziswa njengesongezelelo sokutya ukuphucula ubunjani, incasa kunye nexabiso lesondlo lokutya okuhlukeneyo. Sisithako esiqhelekileyo ekuvelisweni kwesonka, iikeyiki kunye nezinye izinto ezibhakiweyo. Ingasetyenziswa njengesigcini sokwandisa ubomi bokutya okonakalayo.
Ukuqukumbela, iipropati kunye nokusetyenziswa kwe-citraconic anhydride zibanzi kwaye zahlukahlukene. Le khompawundi yendalo eguquguqukayo ifumene indlela yayo kwiinkqubo ezininzi zoshishino, kwaye ukusetyenziswa kwayo kuya kwanda kuphela njengoko kufunyanwa usetyenziso olutsha. Ukusabela kwayo okumangalisayo kunye neepropati zokuyisombulula zenza ukuba ibe yinto ekhangayo kwiintlobo ngeentlobo zezicelo zeekhemikhali, zonyango kunye nokutya.
