I-Ethylene glycol CAS 107-21-1

I-Ethylene glycol, eyaziwa nangokuthi i-glycol, iyi-aliphatic diol elula kakhulu. Inezakhiwo zamakhemikhali zama-alcohols, njengekhono lokukhiqiza ama-ether nama-ester, ukuze afakwe i-oxidized ukuze akhiqize ama-aldehydes noma ama-acid, futhi ajiye ukuze akhiqize ama-ether. Ingashintshwa futhi ngama-halogen. Uma isabela ngama-acyl chloride noma ama-anhydride e-acid, ama-diester avame ukwakheka. Uma ishiswa phambi kwe-catalyst (i-manganese dioxide, i-aluminium oxide, i-zinc oxide noma i-sulfuric acid), ingasuswa emanzini ngaphakathi noma ngaphakathi kwe-molecular ukuze ikhiqize i-cyclic ethylene glycol acetal, esabela ne-nitric acid ukuze ikhiqize i-ethylene glycol dinitrate (into eqhumayo). I-Ethylene glycol iyinto eluhlaza yokukhiqiza ama-polyester resins, ama-alkyd resins, kanye nemicu ye-polyester. Iphinde isetshenziswe njenge-antifreeze yezimoto kanye ne-aircraft engine refrigerant.

Ukubukeka: Uketshezi olungenambala, olubonakalayo, oluqinile

Ukusetshenziswa I-Ethylene glycol isetshenziswa kakhulu njengezinto zokusetshenziswa zemicu ye-polyester, futhi isetshenziswa nakwamanye ama-resin e-polyester, ama-resin e-polyester angagcwali kanye nopende lwe-polyester ka-1730. Izinhlobo ezahlukene zama-surfactants zingatholakala ku-ethylene glycol kanye ne-polyethylene glycol. I-dinitro compound yayo i-dinitroethylene glycol iyisiqhumane. I-Ethylene glycol inganciphisa izinga lokubanda kwezixazululo zamanzi, ngakho-ke ivame ukusetshenziswa njenge-ejenti yokulwa nokubanda.

Indlela yokukhiqiza

1. Indlela yokumanzisa ngqo ye-ethylene oxide

2. Indlela ye-ethylene oxide sulfuric acid catalytic hydration
