Hi, i am working as  junior engineer. Here my problem was solvent distillation. my solvents was THF+n-hexane+n-heptane+ water. so any one suggest me the right method to extract the THF from this mixture.

In a mixture containing TetraHydroFuran + Isopropyl Acetate + MeOH separating the Isopropyl Acetate from the mixture using  Sulphuric Acid. Is this method suitable for this process or there is any other method applicable please suggest me.

This is a similar mixture to this other questions of yours:

Why not post everything in one posting, so we can work together, with what you know, and what you need help with?

Addressing this topic specifically:

separating the Isopropyl Acetate from the mixture using  Sulphuric Acid.

What reaction do you suspect happens, and what reactions do you know?  I'm not familiar with this one, but I will look it up.  Esters like isopropyl acetete are pretty resistant to weak acid, but strong sulfuric will char complex organic compounds like this one.  Which reaction do you want?  What do you expect to happen?  Where did you hear of this method of remediation?

Is this method suitable for this process or there is any other method applicable please suggest me.

Did you just make it up?  We can't help you if you're just going to pick random reagents and ask, "What about this one?" repeatedly.  That's no way for anyone to learn

The Gas Chromatography of the input sample is THF(57.75%)+n-hexane(32.05%)+n-heptane(1.78%) remaining is the water content. After the distillation of the input sample the results were THF(83.2%)+n-heptane(6.6%)+n-hexane(1.9%). We used the DMSO as entrainer. Can anyone suggest the suitable method for THF recovery with purity(>90%) ?

[ramana143]

The process is as follows in the lab scale experiment:
1)Taken IPAc(32.05%) + THF(66.05%) + MeOH(0.4%) input sample and added it to the H2SO4
2)Separation of the layers
3)Taken H2O+NaCl solution added to the sample and separate the Organic Layer
4)Added H2SO4 dropwise to NaCl solution in another flask to form HCl fumes
5)The generated fumes are made to contact with the above Organic Layer (some salt solution gets formed)
6)Added water to the above O.L and separated the O.L
7)Again adding water to the O.L and separating the O.L
8)The separated water layer is mixed with CaSO4 and the formed O.L is separated.

The above mentioned method is whehter compatible with the input sample?

Hi, here my solvent mixture was Isopropyl Acetate+ THF+ Methanol+ Water. I would like to be separate Isopropyl Acetate from this mixture so anyone suggest me the right method to extract isopropyl acetate.
