I-Propylene glycol CAS:57-55-6
Isingeniso somkhiqizo
Igama lesayensi le-propylene glycol lithi "1,2-propanediol". I-racemate iwuketshezi lwe-hygroscopic viscous olunokunambitheka okubaba kancane. Iyaxubeka emanzini, i-acetone, i-ethyl acetate ne-chloroform, futhi inyibilika ku-ether. Incibilika emafutheni amaningi abalulekile, kodwa ayihlangani ne-petroleum ether, upharafini namafutha. Iyazinza ekushiseni nasekukhanyeni, futhi izinzile emazingeni okushisa aphansi. I-Propylene glycol ingafakwa i-oxidized ibe yi-propionaldehyde, i-lactic acid, i-pyruvic acid ne-acetic acid emazingeni okushisa aphezulu.
I-Propylene glycol iyi-diol futhi inezindawo zotshwala obujwayelekile. Ihlangana nama-asidi e-organic kanye nama-asidi angaphili ukukhiqiza ama-monoester noma ama-diester. Isabela nge-propylene oxide ukuze ikhiqize i-ether. Isabela nge-hydrogen halide ukukhiqiza ama-halohydrin. Ihlangana ne-acetaldehyde yenze i-methyldioxolane, uketshezi olungenambala, olubonakalayo noluzinzile olumunca amanzi, olucishe lungabinambitheka futhi lungabi naphunga. Ixubene namanzi, i-ethanol nezinyibilikisi ezihlukahlukene eziphilayo.
Inkambu yohlelo lokusebenza
Isetshenziswa njengempahla eluhlaza yama-resin, ama-plasticizers, ama-surfactants, ama-emulsifiers nama-demulsifiers, kanye ne-antifreeze kanye nezithwali zokushisa.
