1. Izici:
Ukubukeka nokuma komzimba: I-Diethylene glycol monoethyl ether (i-Carbitol) iwuketshezi olucwebe, olungenambala, olunokubambelela okuncane olunephunga elimnandi elincane lezithelo. Kutholakala ngamazinga ahlukahlukene okuhlanzeka okuphezulu (≥99.0% nge-GC) okusetshenziselwa izimboni, ilabhorethri kanye nokusetshenziswa okukhethekile.
Ukuncibilika: I-Carbitol ixubana ngokuphelele namanzi kanye nezincibilikisi eziningi eziphilayo, kufaka phakathi i-acetone, i-benzene, i-chloroform, i-ethanol, i-ethyl ether kanye ne-pyridine. Inhlanganisela yayo yezici ze-hydrophilic ne-hydrophobic ivumela ukuncibilikisa izinhlobonhlobo zezinto, kuhlanganise namafutha, amafutha amaningi, ama-wax, odayi, ama-resin emvelo nawokwenziwa, i-shellac, i-rosin nama-ester e-cellulose.
Izici zamakhemikhali: I-Diethylene glycol monoethyl ether (C₆H₁₄O₃) iyi-glycol ether enezinga lokubila eliphezulu elingu-202°C kanye nezinga lokusha elingu-86–96°C. Inokuguquguquka okuphansi (ingcindezi yomusi <0.07 mm Hg ku-20°C) kanye nezinga lokuhwamuka elihamba kancane, okwenza kube yi-coalescent ephumelelayo kanye ne-film former ezinhlanganisweni zokumboza. Inhlanganisela iyadonsa umswakama futhi kufanele ivikelwe emswakameni womoya. Izinzile ngamakhemikhali, kodwa isabela nama-oxidizing agents anamandla, ama-acids anamandla, ama-acid chlorides kanye nama-acid anhydrides. I-Carbitol inobubanzi obukhulu bokuqhuma (1.8–12.2% ngevolumu) futhi iyasha.
2. Ukusetshenziswa:
Ama-paint, izinto zokumboza kanye neyinki yokunyathelisa (okuyinhloko – isincibilikisi kanye ne-coalescent): I-Carbitol isetshenziswa njenge-coalescent kumapende e-latex, isiza ukwehlisa izinga lokushisa eliphansi lokwakheka kwefilimu. Iyisincibilikisi esingena ngaphakathi kuma-mordants okhuni. Isebenza njengesincibilikisi ezinhlanganisweni zikayinki wokunyathelisa. Iyisincibilikisi esisebenzayo se-cellulose acetate butyrate, nitrocellulose, ama-epoxy resins nezinye izinto zokumboza. Isetshenziswa ezintweni zokuhlanza upende namavarnish.
Ukuhlanza kwezimboni nasemakhaya: I-Carbitol iyingxenye yezihlanzi zemboni, izinto zokususa amafutha kanye nezinto zokuhlanza izindawo eziqinile. Ivimbela ukwakheka kwejeli ezintweni zokuhlanza eziwuketshezi. Isetshenziswa kuzihlanza izinjini zezimoto.
Imboni yezindwangu nezesikhumba: I-Carbitol isebenza njengesincibilikisi sodayi lapho kuphrintwa futhi kudaywa imicu nezindwangu. Isetshenziswa njenge-ejenti yokulungisa intambo nezindwangu. Isebenza njengesincibilikisi, isithwali sombala kanye nesizinzisi se-emulsion ekucutshungulweni kwesikhumba.
Imboni yezimoto kanye noketshezi lwamabhuleki: Ngenxa yezinga lokushisa eliphansi lokuqina kanye nokubambelela okuphansi emazingeni okushisa aphansi, i-Carbitol isetshenziswa ekukhiqizeni uketshezi lwamabhuleki.
Izimonyo nezinto zokuzihlanza: I-Carbitol yenza imisebenzi yokuthambisa, yokunukisa kanye nokuncibilikisa emikhiqizweni yezimonyo. Isetshenziswa ekukhiqizeni insipho nezinto zokudaya.
Ukuhlanganiswa kwamakhemikhali kanye nemikhiqizo ephakathi nendawo: I-Carbitol isebenza njengomkhiqizo waphakathi nendawo ekuhlanganiseni amanye amakhemikhali. Isetshenziswa njenge-extractant yokuhlanza i-vitamin B12 nezinye imikhiqizo yemvelo.
3. Indlela yokukhiqiza:
Inqubo yemboni: I-Diethylene glycol monoethyl ether itholakala ngokuhlanganisa i-ethylene oxide nomoya (ethanol) bese kuhlanjululwa ngokukhishwa kwe-distillation. Umkhiqizo oluhlaza uhlanjululwa uze ube msulwa kakhulu (≥99.0% nge-GC).
4. Ulwazi lokuphepha:
Ukuhlukaniswa kwengozi: I-Carbitol ihlukaniswa njengoketshezi oluvuthayo. Iqukethe izinkomba zengozi: R20 (Ingozi uma ihogwa), nengozi engaba khona yokulimaza ingane ezayo. Igama lesignali: Qaphela. Ayinikeziwe inombolo ye-UN. NFPA 704: Ingozi yezempilo 2, Ukusha 2, Ukungazinzi 0.
Izingozi zempilo: Ingozi uma ihogelwa. Umusi ungabangela ukucasuka kwemigudu yokuphefumula, ikhanda elibuhlungu kanye nokozela. Kungabangela ukucasuka kwesikhumba namehlo. Ingozi uma igwinyiwe. Kungenzeka ingozi enganeni ezayo. Ukuchayeka isikhathi eside kungabangela ukulimala kwesibindi nezinso.
Izinyathelo zosizo lokuqala: Uma ingena emehlweni – geza ngamanzi imizuzu engu-15. Esikhumbeni – geza ngamanzi nensipho. Uma uhogela – umoya omusha. Uma ugwinya – hlambulula umlomo, UNGAHLANZI, bheka udokotela.
Ingozi yomlilo nokuqhuma: Uketshezi oluvuthayo (izinga lokushisa lokuvutha 86–96°C). Ngaphezu kuka-86°C umusi ungakha izingxube eziqhumayo nomoya (1,8–12,2% vol.). Uma kunesomlilo sebenzisa igwebu elimelana notshwala, impushana noma i-CO₂.
Ukugcinwa nokuzinza: Gcina ezitsheni ezivalwe ngokuqinile endaweni epholile, eyomile, enomoya omuhle ngaphansi kuka-+30°C. Isikhathi sokusebenza: izinyanga ezingama-24–60 ezitsheni zokuqala ezivaliwe.
Ukuhambisana nemithetho: I-Diethylene glycol monoethyl ether (CAS#111-90-0, EC#203-919-7) ifakiwe kumarejista e-EINECS, TSCA, DSL. Ilawulwa yi-OSHA ne-ACGIH (PEL: 50 ppm). Ukuze uthole ulwazi oluphelele, bheka i-Pasipoti Yokuphepha (SDS).
