Musiyano uripo pakati pe1,3 propanediol ne1,2 propanediol

1,3-propanediol ne1,2-propanediol zvese zviri zviviri organic compounds zviri muboka re diols, zvinoreva kuti zvine mapoka maviri anoshanda e hydroxyl (-OH). Pasinei nekufanana kwemaumbirwo azvo, zvinoratidza hunhu hwakasiyana uye zvine mashandisirwo akasiyana nekuda kwekurongeka kwemapoka aya anoshanda mukati memaumbirwo awo emamorekuru. 

1,3-Propanediol:

1,3-propanediol, inowanzo pfupikiswa se1,3-PDO, ine fomura yemakemikari C3H8O2. Imvura isina ruvara, isina hwema, uye isina kuravira patembiricha yemumba. Musiyano mukuru muchimiro chayo ndewekuti mapoka maviri ehydroxyl ari pamaatomu ekabhoni akaparadzaniswa neatomu imwe chete ekabhoni. Izvi zvinopa 1,3-PDO hunhu hwayo hwakasiyana.

Hunhu uye Mashandisirwo e1,3-Propanediol:

Chinonyungudutsa:1,3-PDO chinhu chinobatsira pakugadzira zvinhu zvakasiyana-siyana zvepolar nenonpolar nekuda kwechimiro chayo chemakemikari chakasiyana.

Mushonga wekudzivirira kutonhora:Inowanzoshandiswa semushonga unodzivirira kuoma kwechando mumotokari nemumaindasitiri nekuti ine nzvimbo yekuomesa yakaderera pane mvura.

Kugadzirwa kwePolymer: 1,3-PDO inoshandiswa mukugadzira mapolymer anogona kuora senge polytrimethylene terephthalate (PTT). Mabiopolymer aya anoshandiswa mumachira uye mumapakeji.

1,2-Propanediol:

1,2-propanediol, inozivikanwawo sepropylene glycol, ine fomura yemakemikari inonzi C3H8O2 zvakare. Musiyano mukuru ndewekuti mapoka ayo maviri ehydroxyl ari pamaatomu ekabhoni ari pedyo mukati memorekuru.

Hunhu uye Mashandisirwo e1,2-Propanediol (Propylene Glycol):

Mushonga wekudzivirira kuoma nechando: Propylene glycol inowanzo shandiswa semushonga wekudzivirira kuoma nechando mukugadzira chikafu, kudziyisa, uye kutonhodza. Inoshandiswawo semushonga wekudzivirira kuoma nechando mundege.

Chinonhuhwirira:Inoshandiswa muzvigadzirwa zvakasiyana-siyana zvekunakisa uye zvekuchengetedza muviri semushonga wekuchengetedza hunyoro.

Chinowedzera Kudya:Propylene glycol inoiswa muchikamu che "zvinozivikanwa seyakachengeteka" (GRAS) neUS Food and Drug Administration (FDA) uye inoshandiswa sechinhu chinowedzera chikafu, kunyanya sechinotakura manakiro nemavara muindasitiri yechikafu.

Mishonga:Inoshandiswa mune mamwe maformu emishonga semushonga wekugadzirisa uye wekutakura mishonga.

Muchidimbu, musiyano mukuru uripo pakati pe1,3-propanediol ne1,2-propanediol uri mukurongeka kwemapoka avo ehydroxyl mukati mechimiro chemamorekuru. Musiyano uyu wechimiro unotungamira kune hunhu hwakasiyana uye mashandisirwo akasiyana-siyana ema diol maviri aya, ne1,3-propanediol ichishandiswa muzvinonyungudutsa, antifreeze, uye biodegradable polymers, nepo 1,2-propanediol (propylene glycol) ichiwana mashandisirwo mu antifreeze, chikafu, zvizoro, uye mishonga.
