Isingeniso

I-Ethyl allylenate. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-ethyl allylate:

 

Ikhwalithi:

- I-Ethyl allyl proponate iwuketshezi olunephunga elimnandi, elincibilika ezinhlobonhlobo zezinyibilikisi eziphilayo njengotshwala, ama-ether, njll., kodwa ezingancibiliki emanzini.

- I-Ethyl allyl proponate inokusimama okuhle, kodwa i-polymerization ivela ekukhanyeni kwelanga.

 

Sebenzisa:

- I-Ethyl allyl propionate ibalulekile ekuhlanganiseni kwe-organic synthesis, engasetshenziswa ekukhiqizeni imikhiqizo yamakhemikhali njengezinongo, amapulasitiki, nodayi.

- Ingasetshenziswa futhi njenge-solvent emikhakheni yezimboni ezifana nama-coatings, ama-inki, ama-glues, njll.

- I-Ethyl allyl ingasetshenziswa futhi ekulungiseni ama-resin, izinto zokugcoba kanye nama-plasticizers.

 

Indlela:

- I-Ethyl allyl ivame ukwakhiwa ukusabela kwe-ethylene nge-acrylic acid, esuke ifakwe emanzini ku-ethyl allylate.

- Embonini, ama-catalysts afana ne-sulfuric acid avame ukusetshenziselwa ukusiza ukusabela.

 

Ulwazi Lokuphepha:

- I-Ethyl allyl iwuketshezi oluvuthayo futhi kufanele igwenywe ukuthintana namalangabi avulekile, amazinga okushisa aphezulu, nama-oxidizing agents.

- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu, izibuko, nezingubo zokuzivikela lapho usetshenziswa.

- Gwema ukuthinta isikhumba, amehlo kanye nomgudu wokuphefumula we-ethyl allylenate, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha uma kwenzeka.

- Izimo ezinhle zokungenisa umoya kufanele zithathwe lapho ugcina futhi usebenzisa i-ethyl allylenate.

- Uma ulahla imfucuza, landela imithetho yendawo yendawo.
