Separation of Formic Acid from Aqueous Solutions by Liquid Extraction Technique at Different Temperatures
In this study, the separation of formic acid from aqueous solutions was investigated. Liquid-liquid equilibrium (LLE) data including tie-lines was reported for water + formic acid + 2-methylpropyl ethanoate ternary mixture at (293.15 to 323.15) K and atmospheric pressure. The system shows type-I phase behavior based on Treybal’s classification because only one partially miscible binary mixture ...
متن کاملCorrosion and Inhibition Studies of Copper in Aqueous Solutions of Formic Acid and Acetic Acid
Corrosion behaviour of copper has been investigated in different compositions of formic acid and acetic acid at 30°C by a potentiostatic method. The maximum corrosion rate was found in 2&40mol/o formic acid and in 20 mol/o acetic acid in aqueous solution mixtures. The corrosion rate depended on the concentration of either acid. Formic acid is observed to be more corrosive than acetic acid. The ...
متن کاملEquilibrium Study on Reactive Extraction of Acetic Acid with Tri-n-butyl Phosphate in N-hexane
Extraction of carboxylic acids from dilute aqueous solution using traditional solvents such as ketones, alcohols, ethers, and ester is inefficient because the distribution ratio is rather low. Reactive extraction which exploits reversible chemical complexation is an effective separation process for extraction of carboxylic acids from aqueous streams such as fermentation broths and wastewaters. ...
متن کاملCorrosion behaviour of mild steel in aqueous acetic acid solutions containing different amounts of formic acid
The kinetics of mild steel corrosion in 20:0, 19:1, 18:2 and 15:5 (v/v%) aqueous mixture of acetic and formic acids has been investigated by weight loss and potentiostatic polarization techniques. The effects of composition of electrolyte and temperature on the corrosion rate of mild steel have been evaluated. The corrosion rate of mild steel increased linearly with temperature as well as amoun...
متن کاملAcylation of hydrazides with acetic acid and formic acid.
In peptide synthesis, hydrazides are important intermediates for the azide coupling method. A hydrazide is converted to the corresponding azide in the presence of an acid and a nitrite. When acetic acid (or formic acid) is used as the acid, partial acetylation (or formylation) of the hydrazide occurs as a side reaction. Formylation of the hydrazide is much faster than acetylation. Removal of th...
