A thianghlimmi Glacial Acetic Acid – Organic sernak caah a phunphun in hman khawhmi le a hringmi thlennak
A Biapimi Ṭhatnak
1.A sang tukmi thianhlimnak le fek tein um khawhnak:
≥99.5% thianhlimnak nih ttha tein, a ttha ngaimi thlennak a chuahter, a ttha ngaimi sernak caah a ttha (tahchunhnak ah, sii lei thilri, ti bantuk thilri).
2.A phunphun in hman khawhnak:
Lab-Grade: A hmete in lehrulhnak tthaternak le riantuan ning hlathlainak caah aa tlak.
Industrial-Grade: Microwave reactors le high-pressure systems telh in pilot-scale le pehzulh tein thilchuah ning he aa tlak.
3.Himnak & Hmunhma:
A kharmi thilri chiahnak (a luang kho lomi suaisam + inert gas filling) nih ISO 14001 pawngkam phunglam he aa tlakmi, ti a luannak le thurhnawmhnak a kham.
Distillation asiloah adsorption lam in hman tthan khawh a si, thilri rawhralnak 70% leng a zorter.
4.Man-Tthatnak:
A rawkmi acid (tahchunhnak ah, sulphuric acid) kha a fekmi acid thlennak ah a thlen, thilri rawhnak a zorter.
Ionic liquids he riantuan ti in chuahmi a karhter i a lehrulhnak caan a tawiter.
A tlangpi in hmanmi
Sii:
Ibuprofen esterification (98% tiang chuah khawhnak).
Cefalexin cawhnak (thim khawhnak 20% in a karh).
Chemical ttha:
Thil thlum sernak: Thilnung ester (tahchunhnak ah, isoamyl acetate, benzyl acetate) a hringmi chuahternak.
Dye karlak thilri: Benzoic acid chuahmi thilri hna i a tthawngmi oxidation (15% in a zormi thlennak lumnak).
Polymer Science:
Polyester resin sernak: Transesterification hmangin pawngkam caah a ttha mi PET sernak.
Cellulose acetate: Sii lei thilthuam le a rawk khomi thilri chiahnak ah hman a si.
Hlathlainak Chemistry:
HPLC mobile phase timhtuahnak caah polar solvent.
Sample pretreatment: A rawk kho lomi thilri (tahchunhnak ah, alkaloids, steroids) hna i cawhnak.
