Normal Alkanes

Abstract

He holds a B.S. in chemistry from the University of Pennsylvania and is coauthor of several papers dealing with composition, properties, and behavior of petroleum waxes.In addition to waxes his interests include petrochemicals, polymers, and synthetic nutrients. He is a member of the American Chemical Society, the American Association for the Advancement of Science, and the Franklin Institute and a Fellow of the American Institute of Chemists.

Life in oil: Hydrocarbon-degrading bacterial mineralization in oil spill-polluted marine environment

“…The X-ray studies indicate that the ridges formed in certain crystallographic directions on crystals of normal alkanes are related to the shearing which occurs when molecular chains undergo tilting [15]. The normal alkanes have been reported to crystallize into shapes which are often described as plate, needle and mal crystalline in form.…”

On the irrelevance of electrostatics for the crystal structures and polymorphism of long even n‐alkanes

“…a charge set with respect to the reproduction of a crystal energy is to ascertain if the charge set reproduces the experimental order of stability of two polymorphs-assuming that entropy effects can be neglected. For pure, even n-alkanes, two polymorphs exist: a triclinic and a monoclinic structure 6 (we exclude the polytypic form, 7 which is never the thermodynamically most stable form and is formed only owing to its crystallization kinetics). Both polymorphs form homologously isomorphous series, and could theoretically exist for every chain length.…”

Positronium in solid phases of n-alkane binary mixtures

“…The most published papers on mixed alkanes deals with binary ones [16][17][18][19][20]. Typical features of these binary compositions, compared to neat compounds, are:…”
