Musiyano pakati pe1,3 propanediol uye 1,2 propanediol

1,3-propanediol uye 1,2-propanediol ese ari maviri organic compounds ari ekirasi ye diols, zvinoreva kuti ane maviri hydroxyl (-OH) anoshanda mapoka.Pasinei nekufanana kwavo kwechimiro, vanoratidza zvivakwa zvakasiyana uye vane mashandisirwo akasiyana nekuda kwekurongeka kwemapoka anoshanda mukati mezvimiro zvavo zvemamorekuru. 

1,3-Propanediol:

1,3-propanediol, inowanzopfupikiswa se1,3-PDO, ine chimiro chemakemikari C3H8O2.Imvura isina ruvara, isinganhuhwi, uye isinganakidze patembiricha yepakamuri.Musiyano wakakosha muchimiro chayo ndewekuti mapoka maviri ehydroxyl ari pamaatomu ecarbon anopatsanurwa neatomu kabhoni imwe.Izvi zvinopa 1,3-PDO yayo yakasarudzika zvivakwa.

Zvivakwa uye Zvishandiso zve1,3-Propanediol:

Solvent:1,3-PDO inonyungudutsa inobatsira kune akasiyana polar uye nonpolar makomisheni nekuda kweiyo yakasarudzika chimiro chemakemikari.

Antifreeze:Inowanzo shandiswa seantifreeze agent mumotokari uye mumaindasitiri maapplication nekuti ine yakaderera yechando pane mvura.

Kugadzirwa kwePolymer: 1,3-PDO inoshandiswa mukugadzirwa kwemapolymeri anoomeswa senge polytrimethylene terephthalate (PTT).Aya ma biopolymers ane maapplication mumachira uye kurongedza.

1,2-Propanediol:

1,2-propanediol, inozivikanwawo sepropylene glycol, ine chimiro chemakemikari C3H8O2 zvakare.Musiyano wakakosha ndewekuti mapoka ayo maviri ehydroxyl ari padyo neatomu kabhoni mukati memorekuru.

Zvivakwa uye Zvishandiso zve1,2-Propanediol (Propylene Glycol):

Antifreeze uye Deicing Agent: Propylene glycol inowanzoshandiswa se antifreeze mukugadzira chikafu, kupisa, uye kutonhora masisitimu.Inoshandiswawo se deicing agent kune ndege.

Humectant:Inoshandiswa mune dzakasiyana siyana zvekuzora uye zvega zvekuchengetedza zvigadzirwa sehumectant kuchengetedza unyoro.

Chikafu Chinowedzera:Propylene glycol inorondedzerwa se "inowanzo zivikanwa seyakachengeteka" (GRAS) neUS Food and Drug Administration (FDA) uye inoshandiswa sekuwedzera kwechikafu, kunyanya semutakuri wekunaka uye mavara muindasitiri yechikafu.

Pharmaceuticals:Inoshandiswa mune mamwe magadzirirwo emishonga semushonga uye mutakuri wemishonga.

Muchidimbu, mutsauko wakakosha pakati pe1,3-propanediol uye 1,2-propanediol iri mukurongeka kwemapoka avo ehydroxyl mukati meiyo molecular chimiro.Uyu mutsauko wechimiro unotungamira kune akasiyana zvivakwa uye akasiyana mashandisirwo eaya diols maviri, aine 1,3-propanediol iri kushandiswa muzvinonyungudutsa, antifreeze, uye biodegradable polymers, nepo 1,2-propanediol (propylene glycol) inowana maapplication muantifreeze, chikafu, cosmetics. , nemishonga.
