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

Propylene glycol nikintu ukunze kubona murutonde rwibintu byo kwisiga kugirango ukoreshe burimunsi.Bimwe byanditseho 1,2-propanediol nabandi nka1,3-propanediol, ni irihe tandukaniro?
1,2-Propylene glycol, CAS No 57-55-6, molekile ya molekile C3H8O2, ni reagent ya chimique, idashobora gukoreshwa namazi, Ethanol hamwe nudukoko twinshi kama.Nibisukari bitagira ibara byamazi muburyo busanzwe, hafi impumuro nziza kandi biryoshye gato kumpumuro nziza.
Irashobora gukoreshwa nkibikoresho byo kwisiga, kwisiga amenyo hamwe nisabune hamwe na glycerine cyangwa sorbitol.Ikoreshwa nkibikoresho byo guhanagura no kuringaniza amarangi yimisatsi kandi nka antifreeze.
1,3-Propyleneglycol, CAS No 504-63-2, formule ya molekuline ni C3H8O2, ni ibara ritagira ibara, ridafite impumuro nziza, umunyu, hygroscopique viscous fluid, rishobora kuba okiside, esterifike, ikabangikanywa namazi, ikaboneka muri Ethanol, ether.
Irashobora gukoreshwa muguhuza ubwoko bwinshi bwibiyobyabwenge, polyester nshya PTT, abahuza imiti na antioxydants nshya.Nibikoresho fatizo byo gukora polyester idahagije, plasitike, surfactant, emulsifier na emulsion breaker.
Byombi bifite formule imwe kandi ni isomers.
1,2-Propylene glycol ikoreshwa nka antibacterial agent cyangwa porotokoro yinjira muri cosmetike yibanda cyane.
Mugihe cyo hasi cyane, ikoreshwa nkibikoresho bitanga amazi cyangwa ibikoresho byoza.
Mugihe cyo hasi cyane, irashobora gukoreshwa nka pro-solvent kubintu bikora.
Kurakara kuruhu numutekano mubitekerezo bitandukanye biratandukanye rwose.
1,3-Propylene glycol ikoreshwa cyane nkumuti wo kwisiga.Nibikoresho bya polyol organic moisturizing solvent ifasha ibintu byo kwisiga byinjira muruhu.
Ifite imbaraga zohejuru kurusha glycerine, 1,2-propanediol na 1,3-butanediol.Ntabwo ifite gukomera, nta gutwika, nta kibazo cyo kurakara.
Uburyo nyamukuru bwo gukora bwa 1,2-propanediol ni:
1. Uburyo bwa hydride ya propylene;
2. Uburyo bwa propylene butaziguye bwa okiside;
3. Uburyo bwo guhana Ester;4.glycerol hydrolysis synthesis.
1,3-Propylene glycol ikorwa cyane na:
1. Uburyo bw'amazi ya Acrolein;
2. Uburyo bwa okiside ya Ethylene;
3. Uburyo bwa synthesis ya Glycerol hydrolysis;
4. Uburyo bwa Microbiologiya.
1,3-Propylene glycol ihenze kuruta 1,2-Propylene glycol.1,3-Propyleneglycol iraruhije gato kubyara kandi ifite umusaruro muke, igiciro cyayo kiracyari hejuru.
Nyamara, amakuru amwe yerekana ko 1,3-propanediol idatera uburakari kandi itorohewe kuruhu kurenza 1,2-propanediol, ndetse igera no kurwego rwo kutitwara neza.
Kubwibyo, mu myaka yashize, bamwe mu bakora inganda basimbuye 1,2-propanediol na 1,3-propanediol mu bintu byo kwisiga kugira ngo bagabanye ibibazo bishobora kuba ku ruhu.
Kubura uruhu biterwa no kwisiga ntibishobora guterwa na 1,2-propanediol cyangwa 1,3-propanediol yonyine, ariko birashobora no guterwa nimpamvu zitandukanye.Mugihe imyumvire yabantu yubuzima bwo kwisiga n’umutekano igenda yiyongera, isoko rikenewe cyane rizatuma abashoramari benshi batezimbere ibicuruzwa byiza kugirango bahuze ibyifuzo bya benshi mubakunda ubwiza!
