Separation of methacrylic acid from aqueous phase using quaternary amine
The feasibility of extractive reaction of methacrylic acid from aqueous solution using a quaternary amine, tri–octyl methyl ammonium chloride (TOMAC) as an extractant, was studied. The diluents chosen in the present work belong to different chemical classes, n–butyl acetate, carbon tetrachloride, isoamyl alcohol, methyl isobutyl ketone, and toluene. The effect of initial acid concentration in t...

متن کاملSeparation of Carboxylic Acids from Aqueous Solutions using Hollow Fiber Membrane Contactors
Separation of formic, acetic, and propionic acids from the aqueous stream using membrane solvent extraction has been studied using three different membrane contactors made of polysulfone (PS), polyethersulfone (PES), and polyvinylidene fluoride (PVDF) using two different solvents; including ethyl acetate (EA) and diisopropyl ether (DIPE). The efciency of the membrane and e...
متن کاملSeparation of endo-polygalacturonase using aqueous two-phase partitioning.
The partitioning of endo-polygalacturonase (endo-PG) in polyethylene glycol (PEG)-polyvinyl alcohol (PVA10000) and PEG-hydroxypropyl starch (Reppal PES100) aqueous two-phase systems was studied, and revealed the possibility of using aqueous two-phase extraction to purify and concentrate endo-PG from its clarified fermentation broth. For the PEG8000-PVA10000 system, endo-PG presented in the ferm...
متن کاملPhase separation in aqueous solutions of lens y - crystallins : Special role of ys ( ternary mixture / cataract )
We have studied liquid-liquid phase separation in aqueous ternary solutions of calf lens 'y-crystallin proteins. Specifically, we have examined two ternary systems containing ys-namely, yIVa with ys in water and yll with ys in water. For each system, the phase-separation temperatures (Tph(4)))a as a function of the overall protein volume fraction ¢b at various fixed compositions a (the "cloud-p...
