I-Esidi ye-Acetic ye-Glacial ehlanzekileko – Isitjhukumisi esiHlaza satjani se-Organic Synthesis
Iinzuzo eziqakathekileko
Ukuhlanzeka okuphezulu khulu nokuzinza:
≥99.5% ukuhlanzeka kuqinisekisa ukusabela okusebenzako, okukhiqiza khulu, okuhle khulu ekuhlanganisweni okubucayi (isib., izinto eziphakathi kwemithi, izinto ezima-liquid crystal).
2.Ubujamo obuhlukahlukeneko:
Izinga lelebhu: Ilungele ukuthuthukisa ukuphendula okuncani kanye neemfundo zendlela.
Izinga lezamabubulo: Ivumelana neenkambo zokukhiqiza ezijayelekileko neziragela phambili, okufaka hlangana ama-microwave reactors kanye namasistimu we-high-pressure.
3.Ukuphepha nokusimama:
Ukuphakheja okuvaliweko (umklamo ongavuzi + ukugcwaliswa kwegesi engasebenziko) kuvimbela ukuhwamuka nokusilaphazeka, ngokukhambisana namazinga wezebhoduluko we-ISO 14001.
Ingasetjenziswa kabutjha ngokusebenzisa iindlela zokuvundiswa nofana zokudonsa, ukwehlisa ukulahlwa ngama-70%.
Ukusebenza ngeendleko:
Ithatha indawo yama-esidi avuvukako (isib., i-esidi ye-sulfuric) njengesikhuthazi esiqinileko se-asidi, ukunciphisa ukugqwala kwemitjhini.
Isebenzisana nama-ionic liquids ukuthuthukisa isivuno nokunciphisa isikhathi sokuphendula.
Iinsetjenziswa ezijayelekileko
Imithi:
Ukukhiqizwa kwe-ibuprofen (ukukhiqiza okufika ku-98%).
Ukuhlanganiswa kwe-cefalexin (ukukhetha kwanda ngama-20%).
Amakhemikhali amahle:
Ukuhlanganiswa kwefleyiva: Ukukhiqizwa okuhlaza kwama-ester wemvelo (isib., isoamyl acetate, benzyl acetate).
Iinsetjenziswa eziphakathi zedayi: Ukutjhugululwa kwe-oksijini ye-benzoic acid (izinga lokutjhisa lokusabela lehliswe nge-15%).
Isayensi yePholima:
Ukwenziwa kwe-polyester resin: Ukukhiqizwa kwe-PET okunobungani nemvelo ngokusebenzisa i-transesterification.
I-cellulose acetate: Isetjenziselwa ukugqoka kwezokwelapha kanye nokupakisha okubolako.
Ikhemistri yokuhlaziya:
I-polar solvent yokulungiselela isigaba se-HPLC.
Ukulungiswa kwangaphambili kwesampula: Ukuncibilika kwamakhompawundi angancibiliki kuhle (isib., ama-alkaloid, ama-steroid).

Ukupakisha nokugcina
Ubukhulu belebhu: 500mL/1L yamabhodlela weklasi (ama-PTFE stoppers, amelana nomswakama).
Ubukhulu bebubulo: 25kg/200L ISO-standard steel drums (polyethylene-layinied, corrosion-resistant).
Iinsombululo ezikhethekileko: Itholakala ngamaviyoli angama-500mL wokuhlola okusezingeni eliphezulu.
Ubujamo bokubulunga:
Gcina ku-≤30°C eentweni ezivikelwe emkhanyweni; ipilo yetjhelfu iinyanga ezili-12.
Hlala kude nemithombo yokuvutha kanye nama-oksidiza aqinileko; isitoreji esiphakanyisiweko emakhabetheni angaqhumi.
Ikhambisana nokuhlukaniswa kwamakhemikhali we-GHS; I-MSDS (Iphepha Ledatha Yokuphepha Kwezinto) linikelwe.
