Umehluko phakathi kwe-1,3 propantoloy kanye ne-1,2 propanediol

I-1,3-propanediol ne-1,2-Propathediol zombili zezinhlanganisela ze-organic ezingesigaba sama-diols, okusho ukuthi banamaqembu amabili asebenzayo (-Of). Naphezu kokufana kwabo kwesakhiwo, babonisa izakhiwo ezihlukile futhi banezicelo ezihlukile ngenxa yokuhlelwa kwalawa maqembu asebenzayo ngaphakathi kwezinhlaka zawo zamangqamuzana. 

I-1,3-Propanediol:

I-1,3-Propathediol, evame ukufushaniswa njenge-1,3-PDO, inefomula yamakhemikhali C3H8O2. Kungamatshe angenamibala, angenamphunga, futhi angenambitha emazingeni okushisa asekamelweni. Umehluko osemqoka esakhiweni sawo ukuthi amaqembu amabili e-hydroxyl asuselwa kuma-athomu ekhabhoni ehlukaniswe yi-athomu elilodwa lekhabhoni. Lokhu kunikeza i-1,3-PDO yayo ehlukile.

Izakhiwo kanye nokusetshenziswa kwe-1,3-Propanediol:

Solvent:I-1,3-PDO iyi-solvent ewusizo ye-polar ehlukahlukene ye-polar kanye ne-nopolar anpolar ngenxa yesakhiwo sayo esiyingqayizivele samakhemikhali.

Antifreeze:Isetshenziswa kakhulu njenge-ejenti ye-antifreeze ezisetshenziswayo zezimoto nezimboni ngoba inendawo ephansi ebabazekayo kunasemanzini.

Ukukhiqizwa kwe-Polymer: I-1,3-PDO isetshenziswa ekukhiqizweni kwama-polymers afana ne-polymers afana ne-polyrimethylene terephthalate (PTT). Lawa ma-biopolymers anezicelo ezitsheni nasekupakisheni.

I-1,2-Propanediol:

I-1,2-Propanediol, eyaziwa nangokuthi i-PlyLene Glycol, inefomula yamakhemikhali C3H8O2. Umehluko osemqoka ukuthi amaqembu ayo amabili ama-hydroxyl asuselwa kuma-athomu e-carbon aseduze ngaphakathi kwe-molecule.

Izakhiwo kanye nokusetshenziswa kwe-1,2-Propanediol (i-Porylene Glycol):

I-Antifreeze ne-Decing ejenti: I-PlyLene Glycol ivame ukusetshenziswa njenge-antifreeze ekusebenzeni kokudla, ukufudumeza kanye nezinhlelo zokupholisa. Iphinde isetshenziswe njenge-ejenti yokujezisa izindiza.

Zimisele:Isetshenziswa emikhiqizweni ehlukahlukene yokunakekelwa kwezimonyo kanye neyomuntu siqu njengokuzithoba kokugcina umswakama.

Isengezo sokudla:I-Propellene Glycol ihlukaniswa ngokuthi "yamukelwa ngokuvamile njengephephile" (GRAS) yi-US Food and Drug Administration (FDA) futhi isetshenziswa njengempahla yokudla, ngokuyinhloko njengenkampani yenethiwekhi embonini yokudla.

Izemithi:Isetshenziswa kwezinye izindlela zokwehla kwemithi njenge-solvent kanye nenkampani yenethiwekhi yezidakamizwa.

Ngamafuphi, umehluko osemqoka phakathi kwe-1,3-propanediol kanye ne-1,2-propanediol ehlelweni lwamaqembu abo e-hydroxyl ngaphakathi kwesakhiwo samangqamuzana. Lo mehluko wesakhiwo uholela ezizalweni ezihlukile nezinhlelo zokusebenza ezahlukahlukene zalezi zinto ezimbili, ezine-1,3-Propanediol esetshenziswa kuma-solvents, antifreeze, kanti i-1,2-plycol (i-plylene glycol (i-plylene glycol) ithola izinhlelo zokusebenza e-antifreeze, ukudla, izimonyo, kanye nemithi.
