Intshayelelo
I-Methyl 2-methylbutyrate. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-Methyl 2-methylbutyrate yinto engamanzi engenambala kunye nevumba elibi.
- Ukunyibilika: I-Methyl 2-methylbutyrate iyanyibilika kwii-alcohols kunye ne-ethers, kodwa ayinyibiliki emanzini.
Sebenzisa:
- Ukusetyenziswa kwemizi-mveliso: I-Methyl 2-methylbutyrate isetyenziswa rhoqo njenge-solvent ekwenzeni iiplastiki, i-resin, i-coatings, njl.
- Ukusetyenziswa kwelebhu yeMichiza: Ikwasetyenziswa ngokuqhelekileyo njengesixhobo sokwenza izinto kwi-organic synthesis reactions.
Indlela:
Ukulungiswa kwe-methyl 2-methylbutyrate ngokuqhelekileyo kufezekiswa nge-acid-catalyzed esterification reaction. Ngokukodwa, i-ethanol iphendulwa nge-isobutyric acid, kwaye phantsi kweemeko ezifanelekileyo zokuphendula, ezifana nokongezwa kwe-sulfuric acid catalyst kunye nokulawula ubushushu, ukusabela kuvelisa i-methyl 2-methylbutyrate.
Ulwazi ngoKhuseleko:
- I-Methyl 2-methylbutyrate iyilwelo oluvuthayo olunokuvelisa iigesi ezinobuthi kwiqondo lokushisa eliphezulu.
- Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa nee-oxidizing agents ezinamandla xa usebenzisa okanye ukugcinwa.
- Ukudibana nolusu kunokubangela ukucaphuka kunye nokungaguquki, iiglavu ezikhuselayo, iiglasi kunye nempahla ekhuselayo kufuneka inxibe ngexesha lokuphatha.
- Ukuba i-methyl 2-methylbutyrate ifakwe okanye ifakwe, yiya kwindawo ekhupha umoya ngokukhawuleza kwaye ufune unyango ngokukhawuleza.
