Ethylene oxide (ETO)

Usoro nka

Ethylene oxide bụ otu n'ime ether cyclic kacha dị mfe. Ọ bụ ogige heterocyclic. Usoro ọgwụ ya bụ C2H4O. Ọ bụ carcinogen na-egbu egbu na ngwaahịa petrochemical dị mkpa. Njirimara kemịkalụ nke ethylene oxide na-arụ ọrụ nke ukwuu. Ọ nwere ike nweta mmeghachi omume mgbakwunye mgbanaka na ọtụtụ ogige ma nwee ike ibelata nitrate ọlaọcha. Ọ dị mfe iji polymerize mgbe a kpochara ya ma nwee ike ire ere n'ihu nnu ígwè ma ọ bụ oxygen. Ethylene oxide bụ mmiri mmiri na-enweghị agba na nke na-apụta ìhè n'obere okpomọkụ, yana gas na-enweghị ụcha nke nwere ether na-esi ísì na okpomọkụ.

Ethylene oxide nwere mmetụta nje bacteria, ọ naghị emebi emebi na ọla, enweghị isi ọ bụla, ma nwee ike igbu nje bacteria (na endospores ya), ebu na fungi, n'ihi ya, a pụrụ iji ya mee ihe iji kpochapụ ihe ụfọdụ na ihe ndị na-enweghị ike iguzogide okpomọkụ dị elu. . . Ethylene oxide bụ ọgwụ nje kemịkalụ ọgbọ nke abụọ na-esote formaldehyde. Ọ ka bụ otu n'ime ọgwụ nje oyi kacha mma. Ọ bụkwa ihe anọ bụ isi teknụzụ sterilization dị ala (plasma dị ala, uzuoku formaldehyde dị ala, ethylene oxide). , Glutaraldehyde) onye kacha mkpa.

①Sterilization:

Ethylene oxide nwere mmetụta nje bacteria, ọ naghị emebi emebi na ọla, enweghị isi ọ bụla, ma nwee ike igbu nje bacteria (na endospores ya), ebu na fungi, n'ihi ya, a pụrụ iji ya mee ihe iji kpochapụ ihe ụfọdụ na ihe ndị na-enweghị ike iguzogide okpomọkụ dị elu. .
