Determination of Various Properties of Ethyl Actetate + n-Butanol Binary Mixture at Different Temperatures

Abstract

The present study deals with the variations of ultrasonic velocity, density, viscosity, various acoustic and thermodynamic parameters such as adiabatic compressibility, intermolecular free length, molar volume, acoustic impedance, free volume, internal pressure, enthalpy and also excess thermodynamic properties for n-butanol with ethyl acetate as function of concentration and temperature. All the excess parameters are fitted into the Redlich-Kister equation. And also to compare the ultrasonic sound velocity in ethyl acetate with n-butanol mixture from various theoretical relations of Nomoto and Van Dael Vangeel. These properties can be effectively utilized as a qualitative study to predict the extent of molecular interactions between the components.

Synthesizing Easily Erasable Whiteboard Ink Using Locally Available Azadiracta Indica (Neem) Gum

“…Akande&Nwosibe's study proved that producing the ink from locally sourced materials can significantly reduce overall production cost. According to Cueppers & Christoph (7,8) , the faster the ink dries the more easily erasable it is. So the objective of the present work is to synthesize an easily erasable whiteboard ink from the locally available sources that will be user and eco friendly.…”
