Qhov sib txawv ntawm 1,3 propanediol thiab 1,2 propanediol

 

1,3-Propanediol:

1,3-Propanediol, feem ntau cov ntawv luv li 1,3-PDO, muaj cov tshuaj noj tshuaj c3h8o2. Nws yog ib qho tsis muaj kob, tsis muaj ntxhiab, thiab qab ua kua ntawm chav sov. Qhov tseem ceeb sib txawv hauv nws cov qauv yog tias pawg hydroxyl yog nyob ntawm cov roj ntsha atoms uas tau sib cais los ntawm ib cov roj aff. Qhov no muab 1,3-PD end nws cov khoom tshwj xeeb.

Cov khoom thiab cov ntawv thov ntawm 1,3-Propanediol:

Kuab:1,3-PDO yog qhov siv tau siv tau rau ntau lub ncov qaumteb qabteb thiab tsis yog cov duab sib dhos vim nws cov qauv tshuaj tshwj xeeb.

Nws yog ib qho uas siv los ua cov antifrroide tus neeg sawv cev hauv kev siv tsheb thiab kev siv khoom vim tias nws muaj qhov taw tes khov nyob hauv qab dej.

Polymer ntau lawm: 1,3-PDO yog siv nyob rau hauv kev tsim cov khoom lag luam biodegradable polymers zoo li polytrimethylene terephthalate (PTT). Cov biopolers muaj cov ntawv thov hauv textiles thiab ntim khoom.

1,2-propanediol:

1,2-propanediol, tseem hu ua propylene glycol, muaj cov tshuaj noj tshuaj c3h8o2 zoo li. Cov ntsiab lus tseem ceeb yog tias nws ob pawg hydroxyl yog nyob ntawm cov roj ntsha uas nyob ib sab nyob rau hauv cov molecule.

Cov Khoom Siv thiab Kev Siv ntawm 1,2-Propanediol (Propylene Glycol):

Cov tshuaj tiv thaiv kab mob thiab cov neeg sawv cev lav: Propylene Glycol yog ib txwm siv los ua cov tshuaj pleev ib ce hauv kev ua zaub mov noj, cua sov. Nws tseem siv los ua tus neeg saib xyuas kev ua haujlwm rau cov dav hlau.

Humectant:Nws tau siv hauv ntau cov chaw pleev tshuaj thiab cov khoom saib xyuas kev saib xyuas tus kheej ua tus nyiam ua kom muaj ya raws.

Khoom Noj Khoom Haus Ntxiv:

Kws Tshuaj:Nws tau siv nyob rau hauv qee cov kws kho tshuaj ua haujlwm raws li cov kuab tshuaj thiab cov cab kuj rau cov tshuaj.

Hauv cov ntsiab lus, cov ntsiab lus sib txawv ntawm 1,3-Propanediol thiab 1,2-Propanediol lus dag nyob rau hauv kev npaj ntawm lawv cov qauv hydroxyl nyob hauv cov qauv molecular. Cov qauv kev sib txawv no ua rau cov khoom siv sib txawv thiab cov khoom siv sib txawv, nrog rau 1,3-propanediol (propenze glycole, thiab cov protiflec) pom cov tshuaj tua kab mob, khoom noj khoom haus, thiab tshuaj pleev zaub mov.
