Isingeniso

Phenylethyl isovalerate; I-Phenyl 3-methylbutylrate, ifomula yamakhemikhali yi-C12H16O2, isisindo samangqamuzana yi-192.25.

 

Imvelo:

1. Ukubukeka: uketshezi olungenambala, iphunga elimnandi.

2. Ukunyibilika: kuncibilika kuma-alcohols, ethers kanye nezincibilikisi eziningi eziphilayo, ezingancibiliki emanzini.

3. Iphuzu Elincibilikayo:-45 ℃

4. Iphuzu elibilayo: 232-234 ℃

5. Ukuminyana: 1.003g/cm3

6. Inkomba ye-Refractive: 1.502-1.504

7. Iphoyinti elikhanyayo: 99 ℃

 

Sebenzisa:

I-Phenylethyl isovalerate;I-Phenethyl 3-methylbutylrate ivamise ukusetshenziswa njengesithako ezinongo nezinambitheka ezinikeza imikhiqizo iphunga elimnandi lesithelo, njengoshukela wezithelo, iziphuzo zezithelo no-ayisikhilimu. Ngaphezu kwalokho, ingasetshenziswa futhi njengempahla eluhlaza yokuhlanza ama-ejenti, ama-solvents nama-lubricant.

 

Indlela Yokulungiselela:

Phenylethyl isovalerate; I-Phenyl 3-methylbutanol ivame ukulungiswa ukusabela kwe-acetophenone ne-isopropanol phambi kwe-catalyst. Indlela eqondile yokulungiselela imi kanje:

1. Hlanganisa i-acetophenone ne-isopropanol ku-molar ratio.

2. Engeza inani elifanele le-acid catalyst (njenge-sulfuric acid).

3. Hlanganisa isisombululo sokusabela ekushiseni okuphansi (ngokuvamile ku-0-10 ° C). Ezimweni ezivamile, isikhathi sokuphendula singamahora ambalwa kuya kwamashumi amahora.

4. Ngemuva kokuthi ukusabela kuqediwe, umkhiqizo uhlanjululwa ngezinyathelo zokufingqa, ukuhlukaniswa, ukugeza kanye ne-distillation.

 

Ulwazi Lokuphepha:

I-Phenylethyl isovalerate;I-Phenethyl 3-methylbutylrate ngokuvamile ibhekwa njengephephile ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Nokho, iwuketshezi oluvuthayo, gwema ukuchayeka ngokuqondile emalangabini avulekile noma amazinga okushisa aphezulu. Kufanele igcinwe endaweni epholile, enomoya omuhle. Lapho usetshenziswa, gqoka izinto zokuzivikela ezifanele njengamagilavu ​​nezingilazi zokuzivikela. Uma uthinta isikhumba noma amehlo akho ngephutha, hlambulula ngokushesha ngamanzi amaningi. Uma uhogelwe noma ungenwe ngephutha, funa usizo lwezokwelapha ngokushesha.
