1. Izici:
Ukubukeka nokuma komzimba: I-Pentyl acetate (n-amyl acetate) iwuketshezi olucwebe olungenambala uma lucwebile; izinhlobo zezentengiselwano zingaba nombala ophuzi. Inephunga elimnandi elikhethekile likabhanana noma likapheya. Itholakala ngezinhlobo ezahlukene (indinganiso yokuhlaziya, ukuhlanzeka kwe-GC ≥99.5%, ezimbonini).
Ukuncibilika: I-Pentyl acetate incibilika kancane emanzini (10 g/l ku-20°C) futhi ixubana neningi lama-solvent e-organic, kufaka phakathi i-ethanol, i-diethyl ether, i-benzene, i-chloroform ne-carbon disulfide.
Izici zamakhemikhali: I-Pentyl acetate iyi-ester eyakhiwa ukuhlanganiswa kwe-acetic acid ne-1-pentanol (i-amyl alcohol). Lokhu kuwuketshezi olusha olunomlilo onezinga lokushisa lokuvutha okungu-25°C (isitsha esivaliwe) kanye nobubanzi bokugquma emoyeni (1.1–7.5% ngevolumu). Inezinga lokubila elingu-149°C futhi ukuminyana komusi ngu-4,5 (isinda kunomoya).
2. Ukusetshenziswa:
Upende, izinto zokumboza kanye noyinki wokunyathelisa: Isetshenziswa kabanzi njenge-solvent yama-lacquer, upende, i-nitrocellulose nezihlahla. Ingxenye yama-lacquer wezinzipho kanye noyinki bokuphrinta.
Ama-aroma nama-fragrance: Isetshenziswa njenge-flavour kukudla (amaphimbo kabhanana nopele) futhi njengephunga emikhiqizweni yezimonyo neyamakha.
Imboni yezemithi: Isebenza njenge-solvent yokukhipha i-penicillin.
Izicelo zezimboni nezikhethekile: Isetshenziswa ekukhiqizeni ifilimu yezithombe, njengesincibilikisi sama-luminophore ezibani ze-luminescent, ezinhlakeni zama-polish esikhumba, ekuhlobiseni izingubo nasekuhlanganiseni izinkuni, kanye ne-odorant eyisixwayiso emikhiqizweni yezentengiselwano.
3. Indlela yokukhiqiza:
Inqubo yezimboni: I-Pentyl acetate itholakala ngokufaka i-amyl alcohol (1-pentanol) ku-acetic acid ngaphansi kwe-sulfuric acid catalyst bese ilandela i-rectification. Umkhiqizo uhlanjululwa ufinyelele ukuhlanzeka okungu-≥98,5–99,5%.
4. Ulwazi lokuphepha:
Ukuhlukaniswa kwengozi: I-Pentyl acetate ihlukaniswa njengoketshezi oluvutha kalula olunezitatimende zengozi: R10 (Kuyasha), R66 (Ukuphindaphinda kokuchayeka kungabangela ukoma noma ukuqhekeka kwesikhumba). Igama lesignali: Qaphela. Inombolo ye-UN: 1104 (Ikilasi 3, Iqembu lokupakisha III). NFPA 704: Ingozi yezempilo 1, Ukusha 3, Ukungazinzi 0.
Izingozi empilweni: Umhwamuko ungabangela ukucasuka kwemigudu yokuphefumula, ikhanda elibuhlungu, ukozela nesiyezi. Kubangela ukucasuka kwesikhumba namehlo.
Izinyathelo zosizo lokuqala: Uma ingena emehlweni – geza ngamanzi imizuzu engu-15. Esikhumbeni – geza ngamanzi nensipho. Uma ihogela – umoya omusha. Uma kugwinya – UNGAHLANZI, nikeza amanzi noma ubisi, bheka udokotela.
Ingozi yomlilo nokuqhuma: I-liquid evutha kalula (izinga lokuvutha ngu-25°C). Umusi ungakha izingxube eziqhumayo nomoya (1,1–7,5% ngevolumu). Uma kunesomlilo sebenzisa igwebu elimelana notshwala, impushana noma i-CO₂.
Ukugcinwa nokuzinza: Gcina ezitsheni ezivalwe ngokuqinile endaweni epholile, eyomile, enomoya omuhle. Isikhathi sokusebenza: izinyanga ezingama-24–60 ezitsheni zoqobo ezivaliwe.
Ukuhambisana nemithetho: I-Pentyl acetate (CAS#628-63-7, EC#211-047-3) ifakiwe kumarejista e-EINECS, TSCA, DSL. Ilawulwa yi-OSHA (PEL: 100 ppm) kanye ne-ACGIH (TLV: 100 ppm). Ukuze uthole ulwazi oluphelele, bheka i-Pasipoti Yokuphepha (SDS).
