Daim duab 01: Cov qauv ntawm Formaldehyde
Formaldehyde aqueous tov yog flammable thiab corrosive. Thaum npaj cov tshuaj formaldehyde, methanol ntxiv los tiv thaiv formaldehyde los ntawm precipitating li paraformaldehyde. Nyob rau hauv txias txias, formaldehyde nyhav tsim cloudiness nyob rau hauv cov tshuaj vim yog tsim ntawm macromolecules ntawm formaldehyde polymerization.
Muaj ntau daim ntawv thov ntawm formaldehyde hauv kev lag luam thiab lwm qhov chaw. Nws yog siv los ua ib qho precursor rau ntau cov txheej txheem organic synthesis; Piv txwv li, resins xws li melamine resin, phenol-formaldehyde resin. Tsis tas li ntawd, nws yog siv los ua tshuaj tua kab mob. Nws tuaj yeem tua cov kab mob thiab cov kab mob ntawm cov ntoo. Txawm li cas los xij, formaldehyde yog tshuaj lom thiab paub tias yog carcinogenic.
Glutaraldehyde yog dab tsi?
Glutaraldehyde yog ib qho aldehyde molecule uas yog muag li "Cidex". Nws yog ib hom tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tua kab mob, thiab tshuaj kho. Cov tshuaj formula ntawm no compound yog C5H8O2 Nws tshwm sim ua kua ntshiab uas a tsw ntxhiab tsw. Tsis tas li ntawd, cov kua dej no yog miscible nrog dej.
Daim duab 02: Cov qauv tshuaj ntawm Glutaraldehyde
Glutaraldehyde muaj txiaj ntsig zoo li tshuaj tua kab mob, thiab peb tuaj yeem siv cov kua no los ua kom tsis muaj menyuam cov cuab yeej phais thiab lwm qhov chaw hauv tsev kho mob. Glutaraldehyde tuaj yeem siv los ua tshuaj, thiab peb tuaj yeem siv los kho cov kab mob hauv qab ntawm ko taw. Cov tshuaj no yog siv rau hauv nws daim ntawv ua kua.
Txawm li cas los xij, tuaj yeem muaj qee qhov kev mob tshwm sim ntawm glutaraldehyde, suav nrog kev khaus tawv nqaij. Kev raug ntau tuaj yeem ua rau xeev siab, mob taub hau, thiab ua tsis taus pa. Yog li ntawd, peb yuav tsum siv cov cuab yeej tiv thaiv thaum tuav glutaraldehyde. Feem ntau, glutaraldehyde zoo tiv thaiv ntau hom kab mob, xws li spores.
Thaum xav txog cov txheej txheem ntawm kev ua haujlwm hauv glutaraldehyde, nws nyiam ua rau cov amine pawg thiab thiol pawg, zoo ib yam li feem ntau ntawm cov aldehydes peb paub. (amines thiab thiols yog cov pab pawg ua haujlwm hauv cov proteins). Ntxiv mus, nws yog qhov muaj peev xwm sib txuas.
Qhov txawv ntawm Formaldehyde thiab Glutaraldehyde yog dab tsi?
Formaldehyde thiab glutaraldehyde yog cov aldehyde tebchaw uas muaj -CHO ua haujlwm pab pawg. Qhov sib txawv tseem ceeb ntawm formaldehyde thiab glutaraldehyde yog formaldehyde muaj ib pawg aldehyde ua haujlwm, thaum glutaraldehyde muaj ob pawg aldehyde ua haujlwm.
Ntxiv mus, formaldehyde yog tshuaj lom me ntsis thaum glutaraldehyde yog tshuaj lom heev. Tsis tas li ntawd, formaldehyde yog siv los ua cov txheej txheem ua ntej rau ntau cov txheej txheem organic synthesis, ua cov tshuaj tua kab mob, thiab lwm yam thaum glutaraldehyde yog siv los ua tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tua kab mob thiab tshuaj tua kab mob.
Cov hauv qab no infographic teev qhov sib txawv ntawm formaldehyde thiab glutaraldehyde hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Formaldehyde vs Glutaraldehyde
Formaldehyde yog qhov yooj yim tshaj plaws aldehyde compound. Glutaraldehyde yog ib hom di-aldehyde. Qhov sib txawv tseem ceeb ntawm formaldehyde thiab glutaraldehyde yog formaldehyde muaj ib pawg aldehyde ua haujlwm, hos glutaraldehyde muaj ob pawg aldehyde ua haujlwm.
