Isicelo seMveliso:
I-n-Butyric anhydride isetyenziswa ikakhulu njenge-acylation reagent kwi-organic synthesis. Inokusabela ngee-alcohols, i-phenols, i-amines, njl njl ukwenza i-esters ehambelanayo, i-phenolic ethers, i-amides kunye nezinye iikhompawundi. Ibutyric anhydride isenokusetyenziswa njengemathiriyeli ekrwada yepeyinti, iidayi kunye neeplastiki.
Ulwazi ngoKhuseleko:
1.n-I-Butyric anhydride iyacaphukisa kwaye iyatshisa kwaye inokubangela ukucaphuka kwamehlo, ulusu, umjelo wokuphefumla kunye nenkqubo yokwetyisa.
2.Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa nolusu kunye namehlo kunye nokuqinisekisa ukuba umsebenzi wenziwa phantsi kweemeko zomoya.
3. Kwimeko yokunxibelelana ngokungalindelekanga ne-butyric anhydride, gubha ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango.
4.Ngexesha lokugcinwa kunye nokuthutha, kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa nama-oxidising agents kunye nezinto ezinokutsha.
