Itandukaniro riri hagati ya 1,2-propanediol na 1,3-propanediol mu kwisiga

Propylene glycol ni ikintu ukunze kubona ku rutonde rw'ibikoreshwa mu kwisiga buri munsi. Bimwe byanditseho 1,2-propanediol ibindi byanditseho1,3-propanediol, none itandukaniro ni irihe?
1,2-Propylene glycol, CAS No. 57-55-6, formula ya molekile C3H8O2, ni ikintu gikoreshwa mu gukora ibinyabutabire, gishobora kuvangwa n'amazi, ethanol n'ibindi bintu byinshi bikomoka ku bimera. Ni amazi adafite ibara kandi adafite impumuro nziza, hafi ya yose nta mpumuro kandi aryoshye gato iyo ahumuye neza.
Ishobora gukoreshwa nk'umuti wo gutosesha mu mavuta yo kwisiga, mu muti wo koza amenyo no mu isabune hamwe na glycerin cyangwa sorbitol. Ikoreshwa nk'umuti wo gutosesha no kugabanya ubushyuhe mu marangi y'umusatsi ndetse no mu muti urwanya gukonjesha.
1,3-Propyleneglycol, CAS No. 504-63-2, formula ya molekile ni C3H8O2, ni amazi adafite ibara, adafite impumuro, umunyu, afite hygroscopic viscosity, ashobora gukurwamo oxidized, esterized, kuvanga n'amazi, kuvanga muri ethanol, ether.
Ishobora gukoreshwa mu gukora ubwoko bwinshi bw'imiti, polyester PTT nshya, imiti ikoreshwa mu buvuzi ndetse n'irwanya okisidanti nshya. Ni ibikoresho fatizo byo gukora polyester idafite amazi, plasticizer, surfactant, emulsifier na emulsion breaker.
Byombi bifite formula imwe ya molekile kandi ni isomers.
1,2-Propylene glycol ikoreshwa nk'umuti urwanya bagiteri cyangwa ikintu gitera imbaraga mu kwisiga ku rugero rwo hejuru.
Iyo ikoze ku rugero ruto, muri rusange ikoreshwa nk'umuti wo koroshya cyangwa ubufasha bwo gusukura.
Iyo ikoze mu buryo buke, ishobora gukoreshwa nk'ikintu gifasha mu gukora ibintu bikora.
Ubushyuhe bw'uruhu n'umutekano warwo ku rugero rutandukanye biratandukanye rwose.
1,3-Propylene glycol ikoreshwa cyane cyane nk'umusemburo mu kwisiga. Ni umusemburo w'umwimerere wa polyol ufasha ibintu byo kwisiga kwinjira mu ruhu.
Ifite imbaraga zo koroshya kurusha glycerin, 1,2-propanediol na 1,3-butanediol. Ntifite ubukana, ubushyuhe, kandi nta kibazo cyo gushyuha igira.
Uburyo bw'ingenzi bwo gukora 1,2-propanediol ni ubu:
1. Uburyo bwo gutobesha oxide ya propylene;
2. Uburyo bwo gukaranga icyuma cya Propylene;
3. Uburyo bwo gukwirakwiza ester; 4. uburyo bwo gukora glycerol hydrolysis.
1,3-Propylene glycol ikorwa ahanini na:
1. Uburyo bwo gukoresha amazi ya Acrolein;
2. Uburyo bwa etileni okiside;
3. Uburyo bwo gukora Gliseroli hidrolisi;
4. Uburyo bwa mikorobe.
1,3-Propylene glycol irahenze kurusha 1,2-Propylene glycol.1,3-Propyleneglycol iragoye gato kuyikora kandi itanga umusaruro muto, bityo igiciro cyayo kiracyari hejuru.
Ariko, amakuru amwe agaragaza ko 1,3-propanediol idatera uruhu ku buryo budatera uruhu ku buryo budatera uruhu ku buryo budatera uruhu ku buryo budatera uruhu ku buryo budatera uruhu ku buryo bukabije kurusha 1,2-propanediol, ndetse ikaba yagera ku rwego rwo kudatera uruhu ku buryo buteye uburyaryate.
Kubera iyo mpamvu, mu myaka ya vuba aha, bamwe mu bakora ibintu byasimbuje 1,2-propanediol na 1,3-propanediol mu bintu byo kwisiga kugira ngo bagabanye ububabare bushobora kugaragara ku ruhu.
Kubabara k'uruhu guterwa n'amavuta yo kwisiga bishobora kudaterwa na 1,2-propanediol cyangwa 1,3-propanediol gusa, ahubwo bishobora no guterwa n'ibintu bitandukanye. Uko abantu batekereza ku buzima n'umutekano by'ubwiza bikomeza kwiyongera, isoko rirushaho gukenera cyane rizatera inganda nyinshi gukora ibicuruzwa byiza kugira ngo bihuze n'ibyo abakunzi b'ubwiza bakeneye!
