Kevin is from Weed, California
and is the son of Bruce and Margaret. He has two sisters and
one brother. He is a running back for the
WU football team. Outside of football, he enjoys skiing, mountain
biking, and photography.
Kevin finds organic synthesis
intriguing. After graduating from Willamette University, he plans to further
his education in medicine, medicinal chemistry, or pharmaceuticals.

LASER LIGHT SCATTERING MEASUREMENTS OF THE EQUILIBRIUM PHASE TRANSITIONS FOR THE ANILINE/N-HEXANE BINARY LIQUID MIXTURE
|
| Abstract |
|
The chemical phenomenon of solubility has been examined using a laser light scattering approach. The equilibrium phase diagram for the binary liquid-liquid mixture Aniline/n-Hexane has been thoroughly investigated. The equilibrium phase transitions have been determined using the cloud point technique which simultaneously monitors the incident light, Mie Scattering, and Rayleigh scattering. Previous scientists have misinterpreted the various types of light scattering that occur in the critical region of the phase diagram. These mistakes have lead to errors in their phase diagrams by up to a degree Celsius. Consequently, our data reveals their mistakes and provides an accurate approach for determining equilibrium phase transitions for binary liquid mixtures in the region of the critical point. Our data shows a deviation in the region of the critical point primarily due to critical opalescence, and matches well with other scientists work along the sides of the phase diagram where opalescence does not occur.
