Izakhiwo Zomzimba Nezamakhemikhali Izakhiwo zekhemikhali i-3-ethoxy-1,2-propanediol (3-ethoxy-1,2-propanediol), iyi-alphatic ether solvent ye-glycerol emfushane, i-viscous, uketshezi olumunca amanzi oluzinzile, olungenambala futhi olungenaphunga, oluxubana namanzi. , i-ethanol kanye nezinhlobonhlobo zezinyibilikisi eziphilayo.
Sebenzisa Isebenzisa i-3-ethoxy -1, i-2-propanediol iyisiphakathi esibalulekile sokuhlanganiswa kwezinhlanganisela ze-dioxolane. Izingxube ze-Dioxolane ziwumkhiqizo wamakhemikhali owusizo kakhulu, ongaxutshwa nodizili njengophethiloli. I-Dioxolane compounds equkethe ama-athomu e-carbon angu-6-8 ayingxube ye-oxidation enhle kakhulu, futhi ukuxuba nophethiloli we-diesel kunganciphisa Kakhulu ukukhishwa kwezinhlayiya eziqinile kanye ne-NOx ebangelwa ukusha kukadizili.

Isingeniso

I-3-ethoxy-1,2-propanediol iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha kwento:

 

Ikhwalithi:

- Ukubukeka: I-3-Ethoxy-1,2-propanediol iwuketshezi olungenambala oluphuzi olukhanyayo.

- I-Solubility: Incibilika emanzini nasezincibilikisini eziningi eziphilayo, njengotshwala nama-ether.

 

Sebenzisa:

- I-3-ethoxy-1,2-propanediol ivame ukusetshenziswa njengesixazululi nesimaphakathi.

- Ngenxa yokuncibilika kwayo okuhle nokuzinza, ibuye isetshenziswe kabanzi ekulungiseleleni odayi nama-emulsions.

 

Indlela:

Ukuhlanganiswa kwe-3-ethoxy-1,2-propanediol kungenziwa ngezindlela ezilandelayo:

I-1,2-Propanediol isabela nge-chloroethanol.

- Ukusabela kwe-1,2-propanediol ene-ether elandelwa yi-esterification.

 

Ulwazi Lokuphepha:

- Uma uthinta isikhumba noma amehlo, geza ngokushesha ngamanzi amaningi.

- Kufanele igcinwe esitsheni esingangenisi umoya, kude nalapho kubaselwa khona nasezintweni ezikhipha i-oxidizer, ukugwema ingozi yomlilo nokuqhuma.

- Landela umkhuba omuhle waselabhorethri futhi ugqoke izinto zokuzivikela ezifanele ngesikhathi sokusetshenziswa.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
