Propylene glycol me CAS 57-55-6
Ko te 1, 2-propylene glycol he memeha ki te wai, te acetone me te chloroform, ka memeha ki te etera. Ka rewa ki roto i te maha o nga hinu tino nui, engari kaore e uru ki te hinu etera, paraffin me te hinu. Pumau ki te wera me te marama, he pai ake i te pāmahana iti. Ko te 187 ~ 189 ℃ te ira koropupū o te levosome, me te hurihanga motuhake [α]D20-15.0°. Ka taea te oxidized propylene glycol ki propional, waikawa lactic, pyruvate me te waikawa acetic i te pāmahana teitei.

1.Whakamahia rite te kapia, plasticizer, surfactant, emulsifier me te demulsifier raw rauemi, ka taea hoki te whakamahi hei antifreeze me te kawe wera hei whakamahi i te hau chromatographic fixative, whakarewa, antifreeze, plasticizer me te kaihoko dehydrating
2.Carrier whakarewa;
3.Whakamahia mo nga momo mea kakara, nga karaehe, te whakarewa whakamarumaru, te pīni vanilla, te kawhe kawhe pahuhu, te whakarewa tangohanga reka. He kai makuku me te whakangawari mo te reka, te taro, te kai takai, te tiihi, me etahi atu. Ka taea hoki te whakamahi hei kihu, te momo matua mo te aukati koriri AIDS.
Ko te 4.0Propylene glycol he takawaenga i roto i te phenoxymethyclozole fungicide. Ka rite ki te whakarewa, ka taea e ia te whakakore i nga korou, nga poaka, nga antioxidants me etahi atu taapiri kai he uaua ki te memeha ki te wai, katahi ka taapiri atu ki te kai; He kaha te hygroscopic rawa, he makuku me te whakatio i runga i te kai.
