FRACTIONAL SOLIDIFICATION PHENOMENA,

Abstract

Fractional solidification of organic compounds was observed under the microscope. A host of interesting phenomena were noted and are described here. For example, during melting of camphor-anthracene mixtures some of the anthracene crystallites actually grew in size. Inclusions of impurities and of gases in the solid moved toward the melt in some systems and further into the solid in others. Bubbles in the melt sometimes caused agitation of the melt and other times selective growth of a volatile component. (Author)
