Iyini i-2-ethylhexanol nokuthi ungayithenga kanjani i-2-ethylhexanol?

Iyini i-2-ethylhexanol?

I-2-ethylhexanol iyinhlanganisela ye-organic ene-molecular formula C8H18O. Iwuketshezi olungenambala oluvuthayo olunephunga elihlukile.

I-2-ethylhexanol isetshenziswa kakhulu ekukhiqizeni i-plasticizer, i-defoamer, i-dispersant, i-ejenti yokuqedela kanye ne-ejenti yokugcwalisa uwoyela, esetshenziselwa ukuphrinta nokudaya, upende, ifilimu nezinye izici.

Izakhiwo zomzimba ze-2-ethylhexanol

Iphuzu lokuqandisa le I-2-ethylhexanol ingu -75℃, ukuminyana okuhlobene ngu-0.8344 (20/20℃), inkomba ye-refractive ngu-1.4316, i-flash point ingu-81.1℃, i-viscosity (20℃) ingu-9.8mPa·s, umfutho womhwamuko (20℃) ngu-20℃. Ixubene notshwala, i-ether ne-chloroform, inyibilika cishe izikhathi ezingama-720 emanzini. Ku-20℃, ukuncibilika kwe-2-ethylhexanol emanzini ngu-0.1%. I-azeotrope eyenziwe yi-2-ethylhexanol futhi amanzi anephuzu lokubilisa lika-99.1%.

Yiziphi ukusetshenziswa kwe-2-ethylhexanol?

· I-2-ethylhexanol isetshenziselwa ukukhiqizwa kwe-plasticizer, imikhiqizo eyinhloko yilezi: i-octyl phthalate (DOP), i-octyl glycolate (DOA) emibili, i-triphenyl trioctyl ester (TOTM), kanye ne-phthalate, i-azelelic acid, i-sebacic acid kanye nezinye kanambambili i-carboxylic acid ester ester plasticizer kanye ne-plasticizer ebandayo.

· I-2-ethylhexanol ingasetshenziswa njenge-defoamer ye-latex emhlophe, kodwa amandla ayo okuphula amabhamuza futhi avimbele amabhamuza ampofu.

· Uma i-2-ethylhexanol isetshenziselwa ukulungisa isincibilikisi esixubile sikapende we-nitro spray, ingavimbela ifilimu kapende ukuthi ibe mhlophe.

· I-2-ethylhexanol iyi-solvent enhle kakhulu, ingasetshenziselwa ukulinganisa iphepha, i-latex nokuthatha izithombe.

· I-2-ethylhexanol iphinde isetshenziswe ekukhiqizeni ama-surfactants, ama-disperants, ama-lubricant, ama-emulsifiers, ama-antioxidants, ama-dressing agents, ama-mercerizing agents kanye nezithasiselo ze-petroleum.

· I-2-ethylhexanol iyisinongo esivunyelwe futhi isetshenziswa kakhulu ezintweni ezibhakwayo, emikhiqizweni yobisi eqandisiwe kanye nophudingi.

Indlela yokukhiqiza i-2-ethylhexanol?

1. I-carbonyl synthesis

I-Butyl aldehyde ihlanganiswa kusuka ku-propylene kanye ne-syngas nge-carbonyl synthesis. I-2-ethyl (-2-) i-hexenal itholakala ngokuphelelwa amandla kwamanzi, futhi i-2-ethyl (-1-) i-hexanol itholakala nge-hydrogenation.

2. I-acetaldehyde condensation

I-Acetaldehyde ifinyezwa ku-butanol aldehyde, bese i-croton aldehyde itholakala ngokuphelelwa amanzi emzimbeni, futhi i-n-butanal itholakala nge-hydrogenation. I-2-ethyl (-2-) i-hexenal itholwe nge-condensation dehydration yama-molecule amabili we-n-butyral, futhi i-2-ethyl (-1-) i-hexanol itholwe nge-hydrogenation.

3. Ezinye izindlela

Indlela ye-Ethanol condensation, i-rhodium catalyst catalyst heptene indlela, i-copper-chromium catalytic oil kakhukhunathi nezinye izindlela.
