i-trichloroaceticanhydride CAS:4124-31-6

I-Trichloroacetic anhydride (TCAA) isetshenziswa kakhulu ezinhlotsheni ezahlukahlukene emkhakheni wokwenziwa kwezinto eziphilayo. Njenge-acylation reagent, i-TCAA isabela kahle nge-spectrum ebanzi yama-nucleophiles, okuhlanganisa ama-alcohols, ama-amine, nama-thiols, ukuze yakhe ama-acylated derivatives. Lokhu kusebenza kwenza i-TCAA ibe ithuluzi eliwusizo lokuguqulwa nokusebenza kwamakhemikhali e-organic kokubili ezindaweni zelebhu kanye nezimboni. Embonini yezemithi, i-TCAA isetshenziswa ekuhlanganisweni kwezidakamizwa eziphakathi kanye nezithako ezisebenzayo zezemithi (ama-API). Izakhiwo zayo ze-acylating zivumela ukuguqulwa okukhethiwe kwamaqembu athile asebenzayo ngaphakathi kwama-molecule ayinkimbinkimbi, okufaka isandla ekuthuthukisweni kwamakhemikhali amasha emithi anemisebenzi yebhayoloji ethuthukisiwe. Ngaphezu kwalokho, i-TCAA ithola ukusetshenziswa ekukhiqizweni kwamakhemikhali ezolimo, lapho isebenza khona njengesisekelo esiyinhloko sokuhlanganiswa kwemithi yokubulala ukhula, izibulala-zinambuzane, kanye nabalawuli bokukhula kwezitshalo. Ngokwenza kube lula ukwethulwa kwamaqembu e-acyl kuma-molecule aqondiwe, i-TCAA ivumela ukwakheka nokudalwa kwemikhiqizo ye-agrochemical ethuthukisiwe ngempumelelo ethuthukisiwe kanye nomthelela oncishisiwe wemvelo. Ngaphezu kwendima yayo kwezemithi namakhemikhali ezolimo, i-TCAA isetshenziswa ekuhlanganiseni amakhemikhali akhethekile namakhemikhali amahle. Ukusetshenziswa kwayo kufinyelela ekuguqulweni kwemikhiqizo yemvelo, ekulungiseleleni izinto zocwaningo lwamakhemikhali, nasekudalweni kwamakhemikhali asebenzayo athuthukisiwe ezicelo ezahlukahlukene zezimboni. Sekukonke, i-trichloroacetic anhydride (TCAA) imele njenge-reagent eguquguqukayo futhi ebalulekile ekuhlanganisweni kwezinto eziphilayo, idlala indima ebalulekile ekuguqulweni, ekuhlukaniseni, nasekudalweni kwezinto ezibalulekile zamakhemikhali emikhakheni eminingi, kufaka phakathi imithi, amakhemikhali ezolimo, namakhemikhali amahle. Amandla ayo okukhetha ngokukhetha ama-nucleophile ahlukahlukene agcizelela ukubaluleka kwayo njengesisekelo sokwakha ekufuneni izixazululo zamakhemikhali ezintsha zezinselele namathuba anamuhla.
