1. Izici:
Ukubukeka nokuma komzimba: I-2-Methoxyethanol iwuketshezi olucwebezingenambala olunephunga elincane le-ether. Ihlinzekwa ngamakhwalithi ahlukahlukene (ezobuchwepheshe, i-reagent, i-HPLC, engenamanzi) ngobumsulwa obusuka ku-≥99,0% kuya ku-≥99,8%.
Ukuncibilika: I-2-Methoxyethanol ixubana ngokuphelele namanzi, i-ethanol, i-ether, i-acetone, i-glycerol, i-N,N-dimethylformamide kanye nezincibilikisi eziningi ze-organic. Indalo yayo ekabili ye-hydrophilic (utshwala) ne-lipophilic (ether) ivumela ukuncibilikisa izinto eziningi ezihlukahlukene ze-polar ne-non-polar, kuhlanganise namafutha, ama-resin, i-nitrocellulose, odayi kanye nama-lacquer.
Izici zamakhemikhali: I-2-Methoxyethanol iyi-glycol ether ehlanganisa izici zotshwala ne-ether. Lokhu kuwuketshezi oluzinzile, olungenambala, olusha kalula olunezinga lokubila elingu-124–125°C kanye nezinga lokugqama elingu-39–40°C. Umusi usinda kunomoya (ukujiya komusi 2.62) futhi ungakha izingxube eziqhumayo nomoya (imikhawulo yokuqhuma: 1.8–24.5% ngevolumu). Le nto ingakha ama-peroxide aqhumayo uma ithintana nomoya noma ukukhanya futhi isabela nama-oxidizing agents anamandla. I-2-Methoxyethanol inobuthi futhi ihlukaniswa njenge-reproductive toxicant.
2. Ukusetshenziswa:
Upende, izinto zokumboza kanye noyinki wokunyathelisa (okuyinhloko): Isetshenziswa kakhulu njengesincibilikisi se-nitrocellulose, izinhlaka zemvelo nezenziwe, ama-lacquer, ama-enamel kanye ne-stain yokhuni. Isetshenziswa njengesihlukanisi sikapende, isikhuthazi esoma ngokushesha samavanishi nesihlukanisi sezembozo. Kuyingxenye yokopende bokunyathelisa, odayi kanye nezingubo ze-epoxy.
Uphethiloli wendiza: Isetshenziswa njengesengezo sokulwa neqhwa kuphethiloli wendiza.
Imboni yezindwangu nezesikhumba: Isetshenziswa njenge-ejenti yokungena nokulinganisa ekudayeni izindwangu. Isetshenziswa ekucubunguleni isikhumba.
Imboni ye-elekthroniki: Isetshenziswa ezinqubweni ze-photolithography embonini ye-semiconductor.
Izinhlelo zokusebenzisa elabhorethri nokuhlaziya: Isetshenziswa njengendlela yokulinganisa kanye nesincibilikisi se-HPLC, kanye nasezilinganisweni ze-spectrophotometric.
Ukuhlanganiswa kwamakhemikhali: Isebenza njengesandulela ekuhlanganiseni kwezinto eziphilayo, kuhlanganise nokuhlanganiswa kwekhompleksi ye-Vaska kanye nama-photocatalyst asekelwe ku-iridium.
Okunye ukusetshenziswa: Izihlanzi zasezimbonini kanye nezisusa amafutha, amapulasitiki athintana nokudla, isithombe.
3. Indlela yokukhiqiza:
Inqubo yezimboni: I-2-Methoxyethanol itholakala ngokusabela kwe-ethylene oxide ne-methanol. Umkhiqizo uhlanjululwa nge-rectification.
4. Ulwazi lokuphepha:
Ukuhlukaniswa kwengozi: I-2-Methoxyethanol ihlukaniswa njengento eyingozi enezinkomba zengozi: R10 (Kusha kalula), R20/21/22 (Kuyingozi uma kuhogwa, uma kuthintwa isikhumba noma uma kugwinya), R60 (Ingaphazamisa ukuzala), R61 (Ingase ilimaze ingane ezayo). Igama lesignali: Ingozi. Inombolo ye-UN: 1188 (Ikilasi 3, Iqembu lokupakisha III). NFPA 704: Ingozi yezempilo 2, Ukusha 2, Ukungazinzi 1.
Izingozi empilweni: Amaphara angabangela ukukhwehlela, ubuhlungu bomphimbo, ikhanda elibuhlungu, isiyezi, ukozela, isicanucanu nokudideka kwengqondo. Angase angene ngesikhumba. Abangela ukucasuka kwamehlo nesikhumba. Ukuchayeka isikhathi eside kungabangela ukulimala kwe-CNS, igazi, umnkantsha wamathambo, izinso nesibindi. Kubalwa njenge-reproductive toxicant.
Izinyathelo zosizo lokuqala: Uma kungena emehlweni – geza ngamanzi; esikhumbeni – geza ngamanzi nensipho; uma kuhogelwa – umoya omusha; uma kugwinya – hlambulula umlomo, UNGAHLANZI, nikeza amanzi, bheka udokotela.
Ingozi yomlilo nokuqhuma: I-liquid evutha kalula (izinga lokuvutha 39–40°C). Amagesi angakha izingxube eziqhumayo nomoya (1,8–24,5% ngevolumu). Uma kunesomlilo sebenzisa amanzi afafazayo, igwebu, impushana noma i-CO₂.
Ukugcinwa nokuzinza: Gcina ezitsheni ezivalwe ngokuqinile endaweni epholile, eyomile, enomoya ohamba kahle. Into ingakha ama-peroxide; ivamise ukuzinziswa nge-BHT. Isikhathi sokusebenza: izinyanga ezingama-24–60 ezitsheni zoqobo ezivaliwe.
Ukuhambisana nomthetho: I-2-Methoxyethanol (CAS#109-86-4, EC#203-713-7) ifakiwe kumarejista e-EINECS, TSCA, DSL. Ilawulwa yi-OSHA, NIOSH (PEL: 0,1 ppm) kanye ne-ACGIH (TLV: 0,1 ppm). Ihlukaniswa njenge-reproductive toxicant (Isigaba 1B). Ukuze uthole ulwazi oluphelele, bheka i-Safety Data Sheet (SDS).
