Intshayelelo
I-butyl butyrate yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-butyrate:
Umgangatho:
- Imbonakalo: Ibutyl butyrate lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba elimnandi.
- Ukunyibilika: Ibutyl butyrate inokunyibilika kwii-alcohols, ii-ethers kunye nezinyibilikisi eziphilayo, kwaye zinyibilika kancinane emanzini.
Sebenzisa:
- Izinyibilikisi: I-butyl butyrate ingasetyenziswa njenge-solvent ye-organic kwizinto zokwaleka, ii-inki, izinto zokuncamathelisa, njl.
- Ukwenziwa kweekhemikhali: Ibutyl butyrate isenokusetyenziswa njengendawo ephakathi kwi-chemical synthesis yokudityaniswa kwee-esters, ethers, etherketones kunye nezinye iikhompawundi eziphilayo.
Indlela:
Ibutyl butyrate inokwenziwa yi-acid-catalyzed reactions:
Kwisixhobo esifanelekileyo sokuphendula, i-asidi ye-butyric kunye ne-butanol yongezwa kwisitya sokusabela kwisahlulo esithile.
Yongeza ii-catalysts (umz. i-asidi yesulfuric, i-phosphoric acid, njl.).
Fudumeza umxube wokusabela kwaye ugcine ubushushu obufanelekileyo, ngokuqhelekileyo i-60-80 ° C.
Emva kwexesha elithile, ukusabela kuphelile, kwaye imveliso inokufumaneka nge-distillation okanye ezinye iindlela zokwahlula kunye nokucoca.
Ulwazi ngoKhuseleko:
- Ibutyl butyrate yinto enetyhefu ephantsi kwaye ayinabungozi ebantwini phantsi kweemeko eziqhelekileyo zokusetyenziswa.
- Ngexesha lokugcinwa kunye nokuphatha, thintela ukudibanisa ne-oxidants, i-acids eqinile, i-alkali enamandla kunye nezinye izinto ukuphepha ukuphendula okuyingozi.
- Kwimveliso yeshishini kunye nokusetyenziswa, kuyimfuneko ukulandela iinkqubo zokusebenza ezikhuselekileyo kwaye unxibe izixhobo ezifanelekileyo zokukhusela ukuqinisekisa ukusetyenziswa okukhuselekileyo.
