High Purity Glacial Acetic Acid – Catalyst leyi tirhisiwaka hi tindlela to hambana hambana na Green Solvent ya Organic Synthesis
Swipfuno Swa Nkoka
1.Ultra-High Ku basa & ku tshamiseka:
≥99.5% wa ku basa switiyisisa ku tirha kahle, ku cinca cinca ka mbuyelo wale henhla, leswinga kahle eka ti syntheses letinga sensitive (xikombiso, ti pharmaceutical intermediates, switirhisiwa swa liquid crystal).
2.Ku cinca-cinca ka swilo:
Lab-Grade: Yi lulamerile eka swikalo leswintsongo swa reaction optimization na tidyondzo ta mechanistic.
Industrial-Grade: Yi fambelana na maendlelo ya xikalo xa xikambelo na maendlelo ya vuhumelerisi lawa ya yaka emahlweni, kukatsa na ti microwave reactors na tisisiteme ta ntshikelelo wale henhla.
3.Vuhlayiseki & Ku tshamiseka:
Ku pakiwa loku pfaleriweke (leak-proof design + inert gas filling) swi sivela ku khuluka na ku thyakisa, ku landzelela swipimelo swa mbango swa ISO 14001.
Yitlhela yitirhisiwa hiku tirhisa tindlela ta distillation kumbe adsorption, leswi hungutaka thyaka hiku tlula 70%.
4.Ku tirhisiwa ka mali:
Yi cinca ti acids letinga bola (xikombiso, sulfuric acid) tani hi acid catalyst yo tiya, leswi hungutaka ku bola ka switirhisiwa.
Yi tirhisana na ti ionic liquids kuva yi tlakusa mbuyelo xikan’we naku pfuxeta minkarhi ya reaction.
Switirhisiwa leswi Tolovelekeke
Switirhisiwa swa mirhi: .
Esterification ya ibuprofen (mbuyelo kuya fika eka 98%).
Amidation ya cefalexin (ku hlawula ku engetelekile hi 20%).
Tikhemikhali Letinene: .
Ku endliwa ka nantswo: Vuhumelerisi bya rihlaza bya ti esters ta ntumbuluko (xikombiso, isoamyl acetate, benzyl acetate).
Swilo swa le xikarhi swa dayi: Catalytic oxidation ya switirhisiwa swa benzoic acid (mahiselo ya reaction ya hungutiwile hi 15%).
Sayense ya Tipholimer: .
Ku endliwa ka polyester resin: Vuhumelerisi bya PET lebyi nga onhiki ntumbuluko hiku tirhisa transesterification.
Cellulose acetate: Yitirhisiwa eka swisirhelelo swa vutshunguri na ku pakiwa ka biodegradable.
Tikhemikhali ta Nxopaxopo: .
Polar solvent ya ku lulamisiwa ka HPLC mobile phase.
Ku tshunguriwa ka xikombiso: Ku n’okisiwa ka swihlanganisi leswinga khulukiki kahle (xikombiso, alkaloids, steroids).

Ku Pakiwa & Ku Hlayisa
Vukulu bya Lab: . Mabodlhela ya nghilazi ya 500mL/1L (swipfalo swa PTFE, leswi nga ngheniwiki hi ndzhongho).
Vukulu bya Indasitiri: . Swigubu swa nsimbi swa 25kg/200L ISO-standard (leswi nga na polyethylene-lined, leswi nga onhiki).
Switshuxo swa Custom: Yi kumeka eka ti vials ta 500mL eka ku kamberiwa ka high-throughput.
Swiyimo swa Vuhlayiselo:
Hlayisa eka ≤30°C eka swibye leswi sirhelelekeke eka ku vonakala; vutomi bya xelufu 12 wa tinhweti.
Hlayisa ekule na swihlovo swa ignition na ti oxidizers to tiya; ku hlayisiwa loku ringanyetiweke eka tikhabinete leti nga pfurhiki.
Ku fambisana na ku hlawuriwa ka tikhemikhali ta GHS; MSDS (Xiphephana xa Vuhlayiseki bya Switirhisiwa) xi nyikiwile.
