Propylene glycol CAS:57-55-6

wehewehe pōkole:

ʻO ka inoa ʻepekema o propylene glycol ʻo "1,2-propanediol". ʻO ka racemate he wai hygroscopic viscous me kahi ʻono ʻono iki. Hiki ke komo i loko o ka wai, acetone, ethyl acetate a me chloroform, a hiki ke hoʻoheheʻe ʻia i ka etera. Hiki ke hoʻoheheʻe ʻia i loko o nā ʻaila koʻikoʻi he nui, akā hiki ʻole ke hui pū me ka petroleum ether, paraffin a me ka momona. He kūpaʻa i ka wela a me ka māmā, a ʻoi aku ka paʻa i nā haʻahaʻa haʻahaʻa. Hiki ke hoʻoheheʻe ʻia ka propylene glycol i propionaldehyde, lactic acid, pyruvic acid a me acetic acid i nā wela kiʻekiʻe.
ʻO ka propylene glycol he diol a loaʻa iā ia nā waiwai o nā waiʻona maʻamau. Hoʻopili me nā ʻakika organik a me nā ʻakika inorganic e hana i nā monoesters a i ʻole nā ​​mea make. Hoʻopili me ka propylene oxide e hana i ka etera. Hoʻopili me ka hydrogen halide e hana i nā halohydrin. Hoʻopili me ka acetaldehyde e hana i ka methyldioxolane.
Ma ke ʻano he mea bacteriostatic, ua like ka propylene glycol me ka ethanol, a ʻo kona pono i ka pale ʻana i ka mold e like me ka glycerin a haʻahaʻa iki ma mua o ka ethanol. Hoʻohana maʻamau ʻia ka propylene glycol ma ke ʻano he plasticizer i nā mea uhi kiʻiʻoniʻoni wai. Hiki i ka hui ʻana o nā ʻāpana like me ka wai ke lohi i ka hydrolysis o kekahi mau lāʻau lapaʻau a hoʻonui i ka paʻa o ka hoʻomākaukau.
ʻAʻole waihoʻoluʻu, ʻeleʻele a paʻa ka wai hoʻopaʻa wai, aneane ʻaʻohe ʻono a ʻala ʻole. Hiki ke hui pū me ka wai, ethanol a me nā mea hoʻoheheʻe organik like ʻole. Hoʻohana ʻia e like me ka mea maka no nā resins, plasticizers, surfactants, emulsifiers a me demulsifiers, a me ka antifreeze a me nā mea lawe wela.
