Citraconic anhydride chinhu chakasiyana uye chinoshandiswa zvakasiyana-siyana cheorganic chine hunhu hwakasiyana-siyana uye mashandisirwo azvo. Ichi chinhu chisina ruvara checrystalline solid chinowanikwa mukutengeserana uye chinogona kugadzirwa nenzira dzakasiyana-siyana.
Citraconic anhydride iboka remakemikari anozivikanwa secyclic anhydride anoshandiswa zvakanyanya mukugadzirwa kwemakemikari, polymerization, uye mamwe maitiro emaindasitiri. Inoshandiswawo zvakanyanya mukugadzira maresini, machira, pendi uye manamati.
Chimwe chezvinhu zvinoshamisa zve citraconic anhydride ndechekuti inoshanda sei kune ma nucleophiles akasiyana-siyana uye ma electrophiles, izvo zvinoita kuti ikwanise kuita maitiro akawanda emakemikari. Semuenzaniso, inogona kushandiswa sechivako chemamwe ma organic compounds akadai se maleic anhydride, acridine uye pyridine derivatives. Uyezve, inogona kushandiswa semushonga wekugadzirisa ma polymers kana mamwe ma compositions kune zvinangwa zvakasiyana-siyana zvakaita sekuvandudza hunhu hwavo hwepanyama, hwemakemikari kana hwebhayoloji.
Imwe yenzira huru dzekushandisa citraconic anhydride ndeyekugadzira polymer. Nekuda kwekushanda kwayo zvakanyanya, inowanzoshandiswa se monomer kana comonomer mukugadzira mhando dzakasiyana dzepolymer dzakadai se polyesters, polyamides uye vinyl polymers. Zvidzidzo zvakaratidza kuti citraconic anhydride-modified polymers inoratidza hunhu hwepamusoro hwemakanika, kupisa, uye biochemical zvichienzaniswa ne unmodified polymers. Izvi zvinoita kuti ive chinhu chinokwezva chekushandisa muzvishandiso zvekurapa zvakaita se implants, mishonga yekuendesa uye scaffolds yekugadzira tissue.
Imwe nzira inonakidza yekushandisa citraconic anhydride ndeyekunyungudutsa mumakemikari akasiyana-siyana. Izvi zvinokonzerwa nekuti ine hunhu hwakanaka hwekunyungudutsa, izvo zvinoita kuti ikwanise kunyungudutsa mhando dzakasiyana dzemakemikari asina kugadzirwa. Dzimwe ongororo dzakaratidzawo kuti ine hunhu hwemabhakitiriya nehutachiona, zvichiita kuti ishande mukugadzira mishonga inouraya utachiona nekudzivirira utachiona.
Citraconic anhydride inoshandiswawo mumunda wekugadzirwa kwezvinhu zvipenyu. Inogona kushandiswa se reactant kana kutanga kugadzira zvinhu zvakasiyana-siyana zveorganic zvakaita se organic acids, carboxylates, amides, ketones, uye aldehydes. Kuwanda kwe citraconic anhydride ine nucleophiles dzakasiyana-siyana uye electrophiles kunoita kuti ive yakakodzera kugadzirwa kwemamorekuru akaomarara eorganic.
Chekupedzisira, citraconic anhydride inogona kushandiswa sechikafu chinowedzera kunaka, kunaka uye kukosha kwekudya kwezvikafu zvakasiyana-siyana. Chinhu chinowanikwa mukugadzirwa kwechingwa, makeke nezvimwe zvinhu zvakabikwa. Inogonawo kushandiswa sechinochengetedza kuti iwedzere hupenyu hwechikafu chinoora.
Mukupedzisa, hunhu uye mashandisirwo ecitraconic anhydride akasiyana-siyana. Iyi organic compound ine simba rakawanda yakawanikwa mumaindasitiri akawanda, uye kushandiswa kwayo kuchawedzera chete kana mashandisirwo matsva awanikwa. Kushanda kwayo zvinoshamisa uye hunhu hwekugadziriswa kwemvura zvinoita kuti ive chinhu chinokwezva kune akasiyana-siyana mashandisirwo ane chekuita nemakemikari, kurapa uye chikafu.
