. Izici:
Ukubukeka nokuma komzimba: I-2-Ethoxyethanol (EGEE) iwuketshezi olucwebile, olungenambala, olunokubambelela kancane olunephunga elimnandi, elinjenge-ether. Itholakala ngamakhwalithi ahlukahlukene (ezobuchwepheshe, i-ReagentPlus®, ezihlaziyayo, zokuhlanzeka okuphezulu) ngenani lezinto eziyisisekelo elisuka ku-≥99% kuya ku-≥99.8%.
Ukuncibilika: I-2-Ethoxyethanol ixubana ngokuphelele namanzi, i-ethanol, i-ether, i-acetone kanye nezincibilikisi eziningi eziphilayo. Indalo yayo ekabili ye-hydrophilic (utshwala) ne-lipophilic (i-ether) ivumela ukuncibilikisa izinto eziningi ezihlukahlukene ze-polar ne-non-polar, kuhlanganise namafutha, ama-resin, amafutha amaningi, ama-wax, i-nitrocellulose namalaka.
Izici zamakhemikhali: I-2-Ethoxyethanol iyi-glycol ether ehlanganisa izici zotshwala ne-ether. Lokhu kuwuketshezi oluzinzile, olungenambala, olusha kakhulu olunezinga lokubila elingu-135°C nezinga lokusha elingu-40–44°C. Amagesi asindayo kunomoya (ukukhuluphala kwamagesi 3,1) futhi angakha izingxube eziqhumayo nomoya (imikhawulo yokuqhuma: 1,8–15,7% ngevolumu). Into ingakha ama-peroxide aqhumayo futhi isabela nama-oxidizer anamandla, idale ingozi yomlilo nokuqhuma. Idla amapulasitiki amaningi kanye ne-rubber. Isebenza njengesandulela se-ethoxyacetic acid nezinye izinhlanganisela eziphilayo.
2. Ukusetshenziswa:
Ama-paint, ama-coating kanye noyinki wokunyathelisa (okuyinhloko): Isetshenziswa kabanzi njenge-solvent ye-nitrocellulose, izinhlaka zemvelo nezenziwe, kanye namavarnish. Isetshenziswa njengesihlukanisi sikapende, isihlanzi se-varnish kanye nesisusa samafutha. Kuyingxenye yamapende okunyathelisa, imibala kanye noyinki.
Ukuhlanza kwezimboni: Isetshenziswa ezixazululweni zokukhipha amafutha nasezihlanzeni zezimboni. Kuyisakhi esibalulekile sezinto zokususa amavarnish.
Ukuhlanganiswa kwamakhemikhali: Isebenza njengesandulela se-ethoxyacetic acid nezinye izinhlanganisela eziphilayo. Isetshenziswa njenge-semiproduct ekukhiqizeni i-2-ethoxyethyl acetate.
Ukusetshenziswa kwe-analytical kanye nelebhu: Isetshenziswa njenge-extractant ku-HPLC, isincibilizi ku-spectrophotometry, i-co-surfactant ku-microemulsion electrokinetic chromatography.
Okunye ukusetshenziswa: Isiqinisi sokugcina emulshini, umdwebo wesikhumba, ingxenye yoketshezi lwe-hydraulic kanye nezinto zokuvimbela iqhwa, ukuhlanza izingxenye ze-elekthroniki.
3. Indlela yokukhiqiza:
Inqubo yezimboni: I-2-ethoxyethanol ikhiqizwa ngokusabela kwe-ethylene oxide ne-ethanol engamanzi. Umkhiqizo uhlanjululwa nge-rectification. Waqala ukwenziwa ngo-1924 futhi wethulwa ngokwentengiso njenge-Cellosolve.
4. Ulwazi lokuphepha:
Ukuhlukaniswa kwezingozi: I-2-Ethoxyethanol ihlukaniswa njengento eyingozi enezinkomba zengozi: H226 (Ukugeleza okushisayo kanye nomhwamuko), H302 (Kuyingozi uma kugwinya), H331 (Enobuthi uma ihogwa), H360FD (Kungase kulimaze ukuzala. Kungase kulimaze ingane ezayo), H373 (Ingalimaza izitho uma isetshenziswa isikhathi eside noma iphindwa). Igama lesignali: Kuyingozi . Inombolo ye-UN: 1171 (Ikilasi 3, Iqembu Lokupakisha III). NFPA 704: Ingozi yezempilo 2, Ukusha 2, Ukungazinzi 0.
Izingozi empilweni: Inobuthi uma ihogwa. Umusi ungabangela ukukhwehlela, ukozela, ikhanda elibuhlungu nokuphefumula kanzima. Ingangena esikhumbeni. Idala ukucasuka kwamehlo nesikhumba. Ingase ilimaze inzalo noma ingane ezayo. Ukuchayeka isikhathi eside kungabangela ukulimala kohlelo lwezinzwa, igazi, izinso, nesibindi.
Izinyathelo zosizo lokuqala: Uma ingena emehlweni – geza ngamanzi; esikhumbeni – geza ngamanzi nensipho; uma ihogwa – umoya omusha; uma igwinya – hlambulula umlomo, UNGAHLANZI, nikeza amanzi, bheka udokotela.
Ingozi yomlilo nokuqhuma: Ukugeleza okusha kakhulu (izinga lokusha 40–44°C). Umoya ungakha izingxube eziqhumayo nomoya (1.8–15.7% vol.). Uma kunesomlilo sebenzisa amanzi afafazayo, igwebu, impushana noma i-CO₂.
Ukugcinwa nokuzinza: Gcina ezitsheni ezivalwe ngokuqinile endaweni epholile, eyomile, enomoya omuhle. Into ingakha ama-peroxide; ivamise ukuzinziswa nge-BHT. Isikhathi sokusebenza: izinyanga ezingama-24–60 ezitsheni zokuqala ezivaliwe.
Ukuhambisana nomthetho: I-2-Ethoxyethanol (CAS#110-80-5, EC#203-804-1) ifakiwe kumarejista e-EINECS, TSCA, DSL. Ilawulwa yi-OSHA, NIOSH (PEL: 0.5 ppm), ACGIH (TLV: 5 ppm). Ihlukaniswa njenge-toxicant yokuzala (Isigaba 1B). Ukuze uthole ulwazi oluphelele, bheka i-Pasipoti Yokuphepha (SDS).
