Itandukaniro riri hagati ya 1,3 propanediol na 1,2 propanediol

1,3-propanediol na 1,2-propanediol byombi ni ibintu by’umwimerere biri mu itsinda rya diols, bivuze ko bifite amatsinda abiri y’imikorere ya hydroxyl (-OH). Nubwo imiterere yazo isa, zigaragaza imiterere itandukanye kandi zifite ikoreshwa ritandukanye bitewe n’imiterere y’aya matsinda y’imikorere mu miterere yayo ya molekile. 

1,3-Propanediol:

1,3-propanediol, akenshi ihinnye nka 1,3-PDO, ifite formula ya chimique C3H8O2. Ni amazi adafite ibara, adafite impumuro, kandi adafite uburyohe mu bushyuhe bw'icyumba. Itandukaniro rikomeye mu miterere yayo ni uko amatsinda abiri ya hydroxyl aherereye kuri atome za karuboni zitandukanyijwe na atome imwe ya karuboni. Ibi biha 1,3-PDO imiterere yayo yihariye.

Imiterere n'imikorere ya 1,3-Propanediol:

Umushongi:1,3-PDO ni umuti w'ingirakamaro ku bintu bitandukanye byo mu kirere n'ibitari byo mu kirere bitewe n'imiterere yawo yihariye ya shimi.

Irinda gukonjesha:Ikunze gukoreshwa nk'ikintu kirwanya ubukonje mu modoka no mu nganda kuko ifite ubukonje buke ugereranyije n'amazi.

Umusaruro wa polymer: 1,3-PDO ikoreshwa mu gukora polymer zishobora kubora nka polytrimethylene terephthalate (PTT). Izi biopolymer zifite akamaro mu myenda no mu gupfunyika.

1,2-Propanediol:

1,2-propanediol, izwi kandi nka propylene glycol, ifite formula ya chimique C3H8O2. Itandukaniro rikomeye ni uko amatsinda yayo abiri ya hydroxyl aherereye ku atome za karuboni zegeranye muri molekile.

Imiterere n'imikorere ya 1,2-Propanediol (Propylene Glycol):

Irwanya ubukonje n'ubukonje: Propylene glycol ikunze gukoreshwa nk'irwanya ubukonje mu gutunganya ibiribwa, gushyushya no gukonjesha. Ikoreshwa kandi nk'ikoreshwa ry'ubukonje mu ndege.

Humectant:Ikoreshwa mu bikoresho bitandukanye byo kwisiga no kwita ku buzima bwite nk'umuti utuma amazi agumana ubushuhe.

Inyongeramusaruro ku biribwa:Propylene glycol ishyirwa mu cyiciro cya "GRAS" (muri rusange cyemerwa nk'ikidahinduka) n'Ikigo gishinzwe ibiribwa n'imiti muri Amerika (FDA) kandi ikoreshwa nk'inyongeramusaruro ku biribwa, cyane cyane nk'iy'uburyohe n'amabara mu nganda z'ibiribwa.

Imiti:Ikoreshwa mu miti imwe n'imwe nk'umuti uhumanya kandi utwara imiti.

Muri make, itandukaniro rikomeye riri hagati ya 1,3-propanediol na 1,2-propanediol riri mu miterere y’amatsinda ya hydroxyl mu miterere ya molekile. Iri tandukaniro ry’imiterere rituma habaho imiterere itandukanye n’uburyo butandukanye bwo kuyikoresha kuri izi diol ebyiri, aho 1,3-propanediol ikoreshwa mu bintu bishongesha, mu buryo burwanya gukonjesha, no muri polymer zishobora kubora, mu gihe 1,2-propanediol (propylene glycol) ikoreshwa mu buryo burwanya gukonjesha, mu biribwa, mu byo kwisiga, no mu miti.
