Acid ea Glacial Acetic e Hloekileng Haholo – Sethapo se Feto-fetohang le Sethapo se Setala bakeng sa ho Kopanya Lintho tsa Kaho
Melemo ea Bohlokoa
1. Bohloeki le botsitso bo phahameng ka ho fetisisa:
Bohloeki ba ≥99.5% bo netefatsa liketso tse sebetsang hantle, tse nang le chai e ngata, tse loketseng tlhahiso e bonolo (mohlala, metsoako ea meriana, thepa ea kristale ea metsi).
2. Ho feto-fetoha ha maemo:
Sehlopha sa Lab: E loketse ntlafatso ea karabelo e nyane le lithuto tsa mechini.
Boemo ba Indasteri: E lumellana le lits'ebetso tsa tlhahiso tse tsoelang pele le tse tloaelehileng, ho kenyeletsoa li-reactor tsa microwave le litsamaiso tsa khatello e phahameng.
3. Polokeho le Botsitso:
Sephutheloana se koetsoeng (moralo o thibelang ho dutla + ho tlatswa ha khase e sa sebetseng) se thibela mouoane le tšilafalo, se latela maemo a tikoloho a ISO 14001.
E ka sebelisoa hape ka mekhoa ea ho qhibilihisa kapa ea ho monya metsi, e fokotsang litšila ka ho feta 70%.
4. Katleho ea Litšenyehelo:
E nkela li-acid tse senyang sebaka (mohlala, sulfuric acid) sebaka e le sesebelisoa se matla sa asiti, e fokotsang ho bola ha lisebelisoa.
E sebelisana 'moho le li-ionic liquids ho ntlafatsa chai le ho khutsufatsa linako tsa karabelo.
Likopo tse Tloaelehileng
Meriana:
Ho esterization ea ibuprofen (e hlahisa ho fihlela ho 98%).
Ho ba teng ha cefalexin (khetho e eketsehile ka 20%).
Lik'hemik'hale tse Ntle:
Ho kopanya tatso: Tlhahiso e tala ea li-ester tsa tlhaho (mohlala, isoamyl acetate, benzyl acetate).
Di-intermediate tsa dae: Oxidation ya catalytic ya di-derivatives tsa benzoic acid (mocheso wa karabelo o fokotswa ka 15%).
Saense ea Polymer:
Ho etsoa ha resin ea polyester: Tlhahiso ea PET e mosa tikolohong ka transesterification.
Cellulose acetate: E sebelisoa liphahlong tsa bongaka le liphuthelong tse bolang.
Khemistri ea Tlhahlobo:
Solvent ea polar bakeng sa ho lokisa mohato oa HPLC o tsamaeang.
Mohlala oa kalafo pele ho kalafo: Ho qhibiliha ha metsoako e sa qhibiliheng hantle (mohlala, li-alkaloid, li-steroid).

Sephutheloana le Polokelo
Boholo ba laboratori: Libotlolo tsa khalase tsa 500mL/1L (li-PTFE stopper, tse hanelang mongobo).
Boholo ba Indasteri: Meropa ea tšepe ea 25kg/200L ea ISO (e nang le polyethylene, e hanelang mafome).
Litharollo tse Ikhethileng: E fumaneha ka har'a libotlolo tsa 500mL bakeng sa tlhahlobo ea phallo e phahameng.
