1. Izici:

• Ukubukeka nangokomzimba: I-4-Methyl-2-pentanol (MIBC) iwuketshezi olucwebezelayo olungenambala olukhipha iphunga elincane lotshwala. Ithunyelwa ngamakhwalithi ahlukene (ezimbonini ≥98.5%, ezinobumsulwa obuphezulu ≥99.9%, zokwenziwa kwamakhemikhali).

• Ukuncibilika: I-MIBK incibilika kancane emanzini (2% ngesisindo ku-20°C) futhi ixubana neningi lama-solvent e-organic, okuhlanganisa i-ethanol, ama-hydrocarbon kanye nama-solvent anephunga. Ukuncibilika kwayo okuphansi emanzini nokuxubana kwayo okuhle ne-organic kuyenza ibe i-solvent esebenzayo yezinhlaka ezingamanzi, amafutha kanye nama-wax.

• Izici zamakhemikhali: I-MIBK iyi-secondary alcohol enamagatsha. Inezinga lokushisa eliphakathi lokubila (131–135°C), izinga lokushisa lomlilo elingu-41°C (isitsha esivaliwe) futhi ihlukaniswa njengoketshezi oluvuthayo lwekilasi II. Umusi usinda kunomoya futhi ungakha izingxube eziqhumayo nomoya (1.0–5.5% ngevolumu). I-MIBK izinzile ngamakhemikhali, kodwa isabela nama-oxidizer anamandla.

2. Ukusetshenziswa:

• Imboni yezimayini (okuyinhloko – isihlukanisi sokugcwalisa emanzini nge-flotation): I-MIBK ingesinye sezinto ezisetshenziswa kakhulu zokugcwalisa amagwebu ekuhlukaniseni amaminerali e-sulfide kanye ne-non-sulfide, kufaka phakathi amaminerali ethusi, i-molybdenum, i-lead-zinc kanye namalahle.

• Upende, izinto zokumboza kanye noyinki wokunyathelisa: Isetshenziswa njenge-solvent efihliwe ku-nitrocellulose lacquers ukukhulisa ukucwebezela, ukuthuthukisa ukulingana nokunciphisa ukufiphala. Incibilikisa i-nitrocellulose, izinhlaka, ama-wax nemibala. Isetshenziswa kuma-printing inks.

• Izinto zokugcoba kanye nezingxenye zamakhemikhali eziphakathi: Izinto zokusetshenziswa eziyisisekelo zokwenziwa kwe-zinc-dialkyldithiophosphates (ZDDP) – izithasiselo zokulwa nokuguga kanye nokulwa nokugqwala kumafutha enjini. Isebenza njengesandulela ekwenziweni kwezithambisi.

• Ezinye izinto ezisetshenziswayo: Ingxenye yamafutha okubhuleka kanye namafutha e-hydraulic; isincibilikisi ekucubunguleni kwezindwangu, izinamathiselo kanye nezihlanzi zezimboni.

3. Indlela yokuthola:

• Inqubo yezimboni: I-MIBK itholakala ngokufakwa kwe-hydrogen ye-catalytic ye-mesityl oxide, yona etholakala ku-acetone. Umkhiqizo uhlanjululwa nge-rectification ukuze ube nobumsulwa obungu-≥98.5–99.9%.

4. Ulwazi lokuphepha:

• Ukuhlukaniswa kwengozi: I-MIBC ihlukaniswa njengoketshezi oluvutha kalula olunezinkomba zobungozi: R10 (Kuvutha kalula), R37 (Iyacasula imigudu yokuphefumula). Igama lesignali: Qaphela. Inombolo ye-UN: 2053 (Ikilasi 3, Iqembu lokupakisha III). NFPA 704: Ingozi yezempilo 2, Ukusha 2, Ukungazinzi 0.

• Izingozi empilweni: Umoya ongcolile ungabangela ukucasuka kwemigudu yokuphefumula, ikhanda elibuhlungu, ukozela kanye nokulahlekelwa ukwazi. Kubangela ukucasuka kwesikhumba namehlo.

• Izinyathelo zosizo lokuqala: Uma kungena emehlweni – geza ngamanzi imizuzu engu-15. Esikhumbeni – geza ngamanzi nensipho. Uma kuhogela – umoya omusha. Uma kugwinya – phuza umlomo, UNGAHLANZI, bheka udokotela.

• Ingozi yomlilo nokuqhuma: Uketshezi olushisa kalula (izinga lokushisa lomlilo 41°C). Umusi ungakha izingxube eziqhumayo nomoya (1.0–5.5% ngevolumu). Uma kunesomlilo sebenzisa igwebu elimelana notshwala, impushana noma i-CO₂.

• Ukugcinwa nokuzinza: Gcina ezitsheni ezivalwe ngokuqinile endaweni epholile, eyomile, enomoya ohamba kahle. Isikhathi sokusebenza: izinyanga ezingama-24–60 ezitsheni zoqobo ezivaliwe.

• Ukuhambisana nomthetho: I-4-Methyl-2-pentanol (CAS#108-11-2, EC#203-551-7) ifakiwe kurejista ye-EINECS, TSCA, DSL. Ilawulwa yi-OSHA, NIOSH (PEL: 25 ppm) kanye ne-ACGIH (TLV: 20 ppm). Ukuze uthole ulwazi oluphelele, bheka i-Pasipoti Yokuphepha (SDS).
  
  

  

  Ukulayishwa kwesithombe kuyaqhubeka.....

  Ukulanda kwesithombe sangaphandle kwehlulekile. Ukuze umamukeli abone lesi sithombe, sicela ususe lesi sithombe, bese ulanda isithombe endaweni yakho, bese usinamathisela ku-imeyili. https://xinchem.ru/upload/userfiles/images/e64b7fe03a490d42c709685669632f79.jpg
