I-1,8-Octanediol(CAS#629-41-4) Isingeniso
I-1,8-Octanediol iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-1,8-octandiol:
Ikhwalithi:
I-1,8-Caprylyl glycol iwuketshezi olungenambala futhi olusobala olunokunambitheka okumnandi. Inomfutho we-vapor ophansi kanye ne-viscosity ekamelweni lokushisa futhi iyancibilika emanzini nasezincibilikilweni eziningi eziphilayo.
Sebenzisa:
I-1,8-Octanediol inohlu lwezinhlelo zokusebenza. Isetshenziswa kaningi njengezinto ezingavuthiwe zokuthambisa, ama-plasticizer kanye nezinto zokuthambisa.
Indlela:
I-1,8-Octanediol ingalungiswa nge-oxidation ye-octanol. Indlela evamile ukusabela kwe-catalytic oxidation ye-octanol ne-oxygen, lapho i-copper-chromium catalyst ivame ukusetshenziswa.
Ulwazi Lokuphepha:
I-1,8-Octanediol iyinhlanganisela ephephile uma kuqhathaniswa ngaphansi kwezimo ezijwayelekile. Ukuchayeka noma ukuhogela umoya wokugxila okuphezulu kwe-1,8-caprylydiol kungase kubangele ukucasuka emehlweni, isikhumba, kanye nendlela yokuphefumula. Lapho uphatha i-1,8-octanediol, izibuko zokuzivikela, amagilavu namamaski kufanele kugqokwe ukuze kuqinisekiswe umoya omuhle. Qaphela ukuthi ugweme ukuthintana nama-oxidants aqinile kanye nemithombo yokuthungela ukuze uvimbele umlilo noma ukuqhuma. Lapho ugcina futhi uphatha i-1,8-caprylydiol, landela amazinga okusebenza okuphepha afanele nemithethonqubo.
