I-2-Methyl-Propanoic Acid Pentyl Ester(CAS#2445-72-9)
Intshayelelo
I-Amyl isobutyrate. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
I-Amyl isobutyrate lulwelo olungenambala kunye nencasa yamanzi ecaphukisayo kunye ne-pungent. Iyanyibilika kwii-alcohols, ii-ethers kunye ne-organic solvents, kwaye ayinyibiliki emanzini.
Sebenzisa:
I-Amyl isobutyrate isetyenziswa ikakhulu kwizinyibilikisi, izicoci zemizi-mveliso, iipeyinti kunye nezaleko, ii-inki, iziqholo kunye nencasa. Ihlala isetyenziswa njenge-solvent esebenzayo eguquguqukayo kwishishini, enokuthi inyibilikise ngokufanelekileyo izinto ezininzi eziphilayo. Ikwasetyenziswa ngokuqhelekileyo njengemathiriyeli ekrwada kwizinto ezithambisayo, izithambiso kunye neeplastiki.
Indlela:
Ukulungiswa kwe-amyl isobutyrate ngokuqhelekileyo kufumaneka ngokuphendula kwe-isobutanol nge-valeric acid. Kwintsebenzo ethile, i-isobutanol kunye ne-valeric acid zongezwa kwibhotile yokusabela kwinqanaba elithile, kwaye i-catalyst yongezwa ukwenza i-esterification reaction. Emva kokuba impendulo igqityiwe, iimveliso ziyahlukana kwaye zihlanjululwe ngeendlela ezifana ne-distillation.
Ulwazi ngoKhuseleko:
I-Amyl isobutyrate yinto evuthayo evuthayo kwaye iqhume xa ishushu ngomlilo ovulekileyo, ubushushu obuphezulu okanye ilangatye elivulekileyo. Ngethuba lokusetyenziswa okanye ukugcinwa, kufuneka kugcinwe kude namadangatye avulekileyo kunye nemithombo yokushisa, kwaye ibekwe kwindawo epholileyo. Kwimeko yokuvuza ngengozi, amanyathelo okhuseleko ayimfuneko kufuneka athathwe ngexesha, njengokunxiba iiglavu zokukhusela kunye neziphefumla, ukuthintela ukudibana nolusu kunye nokuphefumla umphunga. Kuphephe ukudibana nezinto ezinjengee-oxidants ezinamandla, iiasidi ezinamandla kunye neziseko eziqinileyo zokuthintela ukusabela okuyingozi. Xa uphatha kunye nokuthutha, iindlela ezifanelekileyo zokusebenza ezikhuselekileyo kufuneka ziqwalaselwe, kwaye isixa soqhagamshelwano nomzimba womntu kufuneka silawulwe ngokungqongqo.
