1,3-propanediol na 1,2-propanediol byombi ni ibinyabuzima kama bigizwe nicyiciro cya diol, bivuze ko bifite amatsinda abiri ya hydroxyl (-OH).Nubwo imiterere yabo ihuye, irerekana imitungo itandukanye kandi ifite porogaramu zitandukanye bitewe nuburyo imitunganyirize yaya matsinda ikora murwego rwimikorere ya molekile.
1,3-propanediol, ikunze kwitwa 1,3-PDO, ifite imiti ya C3H8O2.Nibintu bitagira ibara, bidafite impumuro nziza, kandi bitaryoshye mubushyuhe bwicyumba.Itandukaniro ryingenzi mumiterere yaryo nuko amatsinda abiri ya hydroxyl aherereye kuri atome ya karubone itandukanijwe na atome imwe ya karubone.Ibi bitanga 1,3-PDO imiterere yihariye.
Ibyiza nibisabwa bya 1,3-Propanediol:
Umuti:1,3-PDO nigisubizo cyingirakamaro kubintu bitandukanye bya polar na nonpolar bitewe nuburyo bwihariye bwimiti.
Antifreeze:Bikunze gukoreshwa nka antifreeze agent mubikorwa byimodoka ninganda kuko bifite aho bikonje kuruta amazi.
Umusaruro wa Polymer: 1,3-PDO ikoreshwa mugukora polymers ibinyabuzima nka polytrimethylene terephthalate (PTT).Izi biopolymers zifite porogaramu mumyenda no gupakira.
1,2-Propanediol:
1,2-propanediol, izwi kandi nka propylene glycol, ifite imiti ya C3H8O2 nayo.Itandukaniro ryingenzi nuko amatsinda abiri ya hydroxyl aherereye kuri atome ya karubone yegeranye muri molekile.
Ibyiza nibisabwa bya 1,2-Propanediol (Propylene Glycol):
Antifreeze na Deices Agent: Propylene glycol isanzwe ikoreshwa nka antifreeze mugutunganya ibiryo, gushyushya, no gukonjesha.Ikoreshwa kandi nk'umukozi ushinzwe indege.
Urwenya:Ikoreshwa mubintu bitandukanye byo kwisiga no kwita kubantu kugiti cyabo nka humectant kugirango igumane ubushuhe.
Ibiryo byongera ibiryo:Propylene glycol ishyirwa mu rwego rwa "muri rusange izwi nk’umutekano" (GRAS) n’ikigo cy’Amerika gishinzwe ibiribwa n’ibiyobyabwenge (FDA) kandi ikoreshwa nk'inyongeramusaruro, cyane cyane nk'itwara uburyohe n'amabara mu nganda y'ibiribwa.
Imiti:Ikoreshwa mubintu bimwe na bimwe bya farumasi nkibishishwa kandi bitwara ibiyobyabwenge.
Muncamake, itandukaniro ryibanze hagati ya 1,3-propanediol na 1,2-propanediol iri muburyo bwo gutunganya amatsinda ya hydroxyl mumiterere ya molekile.Itandukaniro ryimiterere riganisha kumiterere itandukanye hamwe nuburyo butandukanye bukoreshwa kuri ziriya diol zombi, hamwe na 1,3-propanediol ikoreshwa mumashanyarazi, antifreeze, na biodegradable polymers, mugihe 1,2-propanediol (propylene glycol) isanga ikoreshwa muri antifreeze, ibiryo, kwisiga. , n'imiti.
