I-High Purity Glacial Acetic Acid – I-Catalyst Ehlukahlukene kanye ne-Green Solvent Yokwenziwa Kwezinto Eziphilayo
Izinzuzo Eziyinhloko
1. Ukuhlanzeka Okuphezulu Nokuzinza:
Ubumsulwa obungu-≥99.5% buqinisekisa ukusabela okuphumelelayo nokunesivuno esikhulu, okulungele ukwenziwa okubucayi (isb., izinto zokwelapha ezisetshenziswayo, izinto zekristalu eliwuketshezi).
2. Ukuguquguquka:
Ibanga Lelebhu: Ifanelekela ukwenziwa ngcono kokusabela kwezinga elincane kanye nezifundo zemishini.
Izinga Lezimboni: Iyahambisana nezinqubo zokukhiqiza ezisezingeni lokuhlola kanye neziqhubekayo, okuhlanganisa ama-microwave reactors kanye nezinhlelo zokucindezela okuphezulu.
3. Ukuphepha Nokuzinza:
Ukupakishwa okuvaliwe (umklamo ongavuzi + ukugcwaliswa kwegesi engasebenzi) kuvimbela ukuhwamuka kanye nokungcola, kuhambisana nezindinganiso zemvelo ze-ISO 14001.
Ingaphinde isetshenziswe ngezindlela zokuhluza noma zokufaka i-adsorption, kunciphisa imfucuza ngamaphesenti angaphezu kuka-70.
4. Ukusebenza Kahle Kwezindleko:
Ithatha indawo yama-asidi aqothulayo (isb., i-sulfuric acid) njenge-catalyst enamandla ye-asidi, inciphisa ukugqwala kwemishini.
Isebenzisana noketshezi lwe-ionic ukuze ithuthukise isivuno futhi inciphise izikhathi zokusabela.
Izicelo Ezijwayelekile
Imithi:
Ukuqinisekiswa kwe-ibuprofen (inzuzo ifinyelela ku-98%).
Ukwanda kwe-cefalexin (ukukhetha kukhuphuke ngo-20%).
Amakhemikhali Amahle:
Ukwenziwa kokunambitheka: Ukukhiqizwa okuluhlaza kwama-ester emvelo (isb., i-isoamyl acetate, i-benzyl acetate).
Izinto ezihlanganisa udayi: Ukushiswa kwe-catalytic kwe-benzoic acid derivatives (izinga lokushisa lokusabela lincishiswe ngo-15%).
Isayensi yePolymer:
Ukwenziwa kwe-resin ye-polyester: Ukukhiqizwa kwe-PET enobungani nemvelo ngokusebenzisa i-transesterification.
I-Cellulose acetate: Isetshenziswa ekufakweni kwemithi nasekupakishweni okubolayo.
I-Analytical Chemistry:
Isinyibilikisi se-polar sokulungiselela isigaba seselula se-HPLC.
Isampula yokwelashwa kwangaphambi kwesikhathi: Ukuncibilika kwamakhemikhali angancibiliki kahle (isb., ama-alkaloid, ama-steroids).

Ukupakisha Nokugcina Izinto
Usayizi Welebhu: Amabhodlela engilazi angu-500mL/1L (izivalo ze-PTFE, ezingamelani nomswakama).
Usayizi Wezimboni: Izigubhu zensimbi ezijwayelekile ze-ISO ezingama-25kg/200L (ezimbozwe nge-polyethylene, ezingagqwali).
Izixazululo Zenziwe Ngokwezifiso: Itholakala emabhodleleni angu-500mL ukuze kuhlolwe umthamo ophezulu.
Izimo Zokugcina:
Gcina ku-≤30°C ezitsheni ezivikelwe ukukhanya; isikhathi sokugcinwa kweshalofu izinyanga ezingu-12.
Gcina kude nemithombo yokushisa kanye nama-oxidizer aqinile; kutuswa ukuthi ugcine emakhabetheni angaqhumi.
Ihambisana nokuhlukaniswa kwamakhemikhali e-GHS; i-MSDS (Ishidi Ledatha Yokuphepha Kwezinto Ezibalulekile) inikeziwe.
