Propyl utshwala: izindawo kanye nezicelo

I-propyl utshwala inezinhlobo eziningi zokusebenza. I-solvent ehle kakhulu yama-alkaloids, amafutha amaningi abalulekile, amanye ama-resin zokwenziwa, njll.

Ukuthandwa kwe-isopropyl utshwala kuhlobene nokuthi iningi lezinto eziphilayo (ama-esters, amafutha, ama-waxes, lipids, njll). Embonini, i-isopropanol ikhiqizwa yi- hydration ngqo ye-propylene. Into esemqoka yokusetshenziswa kwe-isopropanol iyinxenye yepropylene ye-pyrolysis gesi yamafutha kanye nengxenyana ye-propane-propylene yama-gas cracking gas.

I-propyl utshwala isetshenziselwa ukunyathelisa, amafutha, amakhemikhali, ezokwelapha, ukudla, ifenisha, izimboni zamakhemikhali namapulangwe.

Ekunyatheliseni, i-isopropanol isetshenziselwa ukunyathelisa izinqubo zokumisa. I-Propyl utshwala yiyona eyinhloko yokwakheka kwe-acetone, i-isopropyl ethanoate, namanye ama-esters. Ukukhiqizwa kwamaplastiki yanamuhla akuyona ngaphandle kokusebenzisa i-isopropanol.

I-propyl utshwala isetshenziselwa ukugeza i-polypropylene. Imbonini yePaint kanye ne-varnish lokhu kusetshenziswa i-ethyl, i-acetyl ne-nitrocellulose njengesixazululo esisizayo. I-Isopropanol - esinye sezixazululo ezibaluleke kakhulu ekukhiqizeni i-nitro-lacquers. Lesi sitho sithola isicelo ekuthuthweni kwe-nitrocellulose.

I-Isopropyl alcohol ingathengwa cishe kuzo zonke izitolo ezikhethekile. Ungayithenga enkampanini ethengisa amakhemikhali. I-Isopropyl utshwala yi- antiseptic enhle kakhulu . Izakhiwo zalo zokubulala amagciwane ziphakeme kakhulu kune-ethanol. Ngenxa yezindawo zayo eziyingqayizivele, i-isopropanol isetshenziswa:

- ekwenzeni izimonyo namafutha;

- ekwenzeni izinhlayiya, izakhi, ama-extractants ezempilo;

- njenge-antiseptic;

- njenge-solvent ngenkathi kusetshenzwa kabusha futhi njenge-preservative;

- embonini yamakhemikhali yezinkuni ukukhishwa kwama-resin ezikhuni;

- embonini yefenisha njengesixazululo sezinhlobonhlobo zama-adhesives namafutha;

- embonini yamakhemikhali yokudonswa kwe-ethanol ngenkathi kulungiselelwa ukuqhuma amanzi;

- ku-aircraft isetshenziselwa ukuqiniswa kwe-anti-icing kanye ne-aviation gasoline;

- njenge-windshield washer fluid.

Namuhla, isidingo se-isopropanol sikhula ngokushesha, okubangelwa ukusetshenziswa kwalesi sici njengengxenye yamaprolithi okwandisa inombolo yayo ye- octane. Ngokusetshenziswa kwalokhu utshwala, ukusebenza kwephethiloli kuyithuthukisiwe (ukumelana nokukhwabanisa kwanda, ukukhishwa kwezinto ezinobuthi - CH, CO) kuncishisiwe. Iningi lamabhizinisi amakhemikhali ezwe lakithi "ahlomile" ngobuchwepheshe banamuhla kanye nemishini emisha, eyenza bakwazi ukukhiqiza imikhiqizo enokuncintisana nephezulu. Kusukela emaqinisweni angenhla kungaphetha ngokuthi i-isopropanol iyindlela ejwayelekile futhi efunwa yizo zonke izinhlobo zemikhiqizo yokukhiqiza nemisebenzi yabantu.
