Mar 08, 2018 · 0.64 M and 3.8% (lower than claim) First, you want to start by using the titration information to find the molarity of the acetic acid. M_1*V_1=M_2*V_2 Where 1 is the acetic acid and 2 is the sodium hydroxide. The product of molarity and volume of the sodium hydroxide provides the moles of the solution and the moles are equal in the acetic acid when completely titrated.

If you really must remove corrosive materials such as propionic/acetic acid, make sure you attach a second liquid nitrogen trap before the solvent passes through the vacuum. This will prolong the life of the pump. Some solvents/reagents are not really suitable for rotary evaporation, unless the exhaust from your vacuum pump is vented into a .

What Is A Rotovap / Rotary Evaporator Used For? - WKIE LAB

The Importance of Rotovap In the Experiment. Rotary evaporation is applied regularly and is useful for separating "low boiling" solvents, such as the derivation of n-hexane or ethyl acetic acid from potent mixtures at room temperature and pressure.

Basic Rotovap Structure and Design - Lab Instrument .

Rotary evaporator, or rotovap, is an instrument used to distill a solvent.(Everyone calls it a "rotovap" even though rotovap is a brand name). The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).

Trifluoroacetic Acid (TFA) - Common Organic Chemistry

Trifluoroacetic Acid (TFA) - Common Organic Chemistry

TFA is the CF3 analogue of acetic acid which due to the electron withdrawing effect of the fluorine atoms is much more acidic than AcOH. The pKa of TFA is 0.23, compared to a pKa of 4.76 for AcOH. The low boiling point (bp = 72 C) of TFA facilitates simpler product isolation due to the fact that it can be removed via concentration on rotovap.

Sampling and Analytical Methods: Acetic Acid, PV2119

The wet extraction efficiency was determined at 1 times the target concentration by liquid spiking the acetic acid onto charcoal tubes which had 10-L humid air (absolute humidity of 15.9 mg/L of water, about 80% relative humidity at 22.2ºC) drawn through them immediately before spiking. The mean recovery for the wet samples was 99.0%.
