Technical Performance index
Raws li GB25554-2010 tus qauv khoom ntsuas tus nqi acid (KOH) / (mg / g) ≤2.0 saponification tus nqi (KOH) / (mg / g) 45-55 hydroxyl tus nqi (KOH) / (mg / g) 6chemicalbook5-80 noo noo, w/% ≤3.0 burning residue, w/% ≤0.25 Arsenic (As)/(mg/kg) ≤3 lead (Pb)/(mg/kg) ≤ 2-oxyethylene (C2H4O), w/%65.0 ~ 69.5 ib
Txoj kev tsim khoom
1mol Span-80 tau preheated thiab muab tso rau hauv cov tshuaj tiv thaiv kettle, ntxiv catalyzed sodium hydroxide aqueous tov nyob rau hauv stirring, stirring, nqus thiab lub cev qhuav dej.Tom qab hloov cov huab cua hauv lub lauj kaub nrog nitrogen, 22mol ethylene oxide pib ntws thaum qhov kub nce mus txog 140 ℃, thiab qhov kub ntawm cov ntaub ntawv rov qab tau khaws cia ntawm 180 ~ 190 ℃.Tom qab cov ethylene oxide dhau lawm, lub tshuab nqus tsev tau nres.Tom qab txias, cov khoom ua kua yog tsav mus rau hauv lub neutralization kettle thiab neutralized nrog acetic acid kom txog thaum cov kua qaub yog li ntawm 2, thiab ces decolorized nrog ib tug tsim nyog tus nqi ntawm hydrogen peroxide.Thaum kawg, cov khoom siv lub cev qhuav dej kom txog thaum cov dej muaj 3%, thiab cov khoom tiav tuaj yeem tau txais los ntawm kev ntim khoom txias.
