Umahluko phakathi kwe-1,3 propadiol kunye ne-1,2 propadiol

I-1,3-propadiol kunye ne-1,2-propadiol zizinto eziphilayo zeklasi yeklasi yeDiols, okuthetha ukuba zinee-hydroxyl ezimbini (---). Ngaphandle kokufana nolwakhiwo, babonisa iipropathi ezahlukeneyo kwaye banezicelo ezahlukeneyo ngenxa yezi qela zisebenzayo ngaphakathi kwezakhiwo zazo zemolekyuli. 

I-1,3-propadiol:

I-1,3-propadineol, ihlala ifinyezwe njenge-1,3-iphedo, ineefomula zekhemicamicamicaco c3h8h8o2. Yinto engenamibala, engenamanzi, kwaye ingenalo i-olwed engathandekiyo kubushushu begumbi. Umahluko ophambili kwisakhiwo sayo kukuba amaqela amabini e-hydroxyl ami kwi-atom yekharbon ahlukaniswe yi-atom enye yecarbon. Oku kunika i-1,3-PDO Ipropathi yayo eyahlukileyo.

Iipropathi kunye nokusetyenziswa kwe-1,3-propadiol:

I-Solvent:I-1,3-PDO yiShorvent elungileyo ye-polar kunye ne-nonpolar emanzini ngenxa yesakhiwo sayo esikhethekileyo.

I-Antifowreeze:Ihlala isetyenziswa njengearhente ye-antifreeze kwizicelo zemoto kunye nezixhobo kuba inendawo ephantsi yenkunkuma kunamanzi.

Imveliso yePolymer: I-1,3-PDO isetyenziswa ekuvelisweni kwee-billys ezinobungozi njenge-polytrimene terephthane terephrhane terephthalate (PTT). Ezi biopolymers zinokufakwa kwezicelo kunye nokupakisha.

I-1,2-propadiol:

I-1,2-propadinediol, ebizwa ngokuba yi-propylene glycone, inefomula yekhemicamicamicaco C3H8H8H8H8O2 ngokunjalo. Umahluko ophambili kukuba amaqela ayo amabini e-hydroxyl ami kwi-atom akufuphi kwimolekyuli.

Iipropathi kunye nokusetyenziswa kwe-1,2-propadiol (Propylene Glycol):

Iarhente ye-antifowrole kunye ne-Depylene Glycol isetyenziswa njengokuhonjiswa okukuko, ukufudumeza, kunye neenkqubo zokupholisa. Ikwasetyenziswa njenge-arhente yokusebenza ngenqwelomoya.

Himectant:Isetyenziswe kwiimveliso ezahlukeneyo zokhathalelo kunye neemveliso zobuqu njengezimgangatho wokugcina umswakama.

UkutyaI-propylene glycol ihlelwe njenge "ishwankathelwa njengezinto ezikhuselekileyo" (i-GRAs) nguLawulo lwe-US (i-FDA) kwaye isetyenziswa njengokuthwayo, ikakhulu njengomphathi weencasa kunye nemibala kwishishini lokutya.

Amayeza:Isetyenziswe kwifomu ethile yeyeza njengesinyibilikisi kunye nomphathi weziyobisi.

Isishwankathelo, umahluko ophambili phakathi kwe-1,3-propadiol kunye ne-1,2-propadiol ilele kulungiselelo lwamaqela abo e-hydroxyl ngaphakathi kwesakhiwo semolekyuli. Umahluko wesakhiwo ukhokelela kwizicelo ezahlukileyo kunye nezicelo ezahlukileyo kwezi zimbini, isetyenziswa kwi-1,3-propadiol, i-antifleze, ne-1,2-propacol (i-propadiol (propayini) ifumana izicelo zokungasebenziyo, ukutya, kunye namayeza.
