Isobutylene is an important bulk chemical for the petroleum industry. Dimerization and hydrogenation reactions produce the standard fuel octane rating comparison. This classic chemistry is often misrepresented in modern texts, however, and this paper attempts to correlate the physical organic principles that apply. (Author)

Carbon Monoxide obtained from coal may serve as the source for a wide variety of organic compounds. Several of these compounds are discussed, including phosgene, benzaldehyde, methanol, formic acid and its derivatives, oxo aldehydes, acrylic acids, and others. Commercial reactions of carbon monoxide are highlighted in a table. (JN)

Explanations and four examples are provided which illustrate four steps needed to locate an organic compound in the Beilstein Handbook. (SK)

Synthesis and polymerization of vinyl monomers that double as stabilizers against degradation of plastics by ultraviolet light has been accomplished. Potential applications include protection of photovoltaic cells in solar power plants. (Author/RE)

Since the usefulness of cyclic point groups is oftentimes neglected in textbooks, suggestions are given for writing down tables of characteristics for these groups. (SK)

A brief review is presented of some of the organic compounds and reactions that occur in soil. Included are nitrogenous compounds, compounds of phosphorus and sulfur, carbohydrates, phenolic compounds, and aliphatic acids. (BB)

Presented is a brief review of the chemistry of grasses. The significance of the main constituents of agriculturally important grasses is discussed in relation to ruminant nutrition. (BB)

Presents a diagram that illustrates the epimeric and other isomeric relationships that exist among the aldohexoses. (HM)

Molecular models are described which are suitable for illustrating the nucleic acids. The same principles used to construct these could be applied to models of polypeptides. (BB)
