This is the sixth annual report of the U.S. Trade Commission on domestic production and sales of synthetic organic chemicals and the raw materials from which they are made. The report consists of 15 sections, each covering a specified group (based primarily on use) of organic chemicals as follows: tar and tar crudes; primary products from…

This module sketches out the impact of sewage organic matter on soils. For convenience, that organic matter is separated into the readily decomposable compounds and the more resistant material (volatile suspended solids, refractory organics, and sludges). The fates of those organics are reviewed along with loading rates and recommended soil…

Reviews the history of selected topics in organic chemistry, including organic synthesis, free-radicals, and instrumentation. (MLH)

Describes an organic chemistry experiment that illustrates dimerization, gas chromatography analysis and separation, and the thermodynamic basis for Markovnikov's rule. (MLH)

Discusses the use of reaction mechanisms rather than functional groups as a basis for organizing and teaching organic chemistry. (MLH)

Describes two tests, T-4 and T-3, for hypothyroid based on the binding of the hormones by proteins. The tests were performed in courses for physicians, clinical chemists, laboratory technicians, and undergraduate science students by the individuals involved and on their own sera. These tests are commercially available in kit form. (GA)

Discusses the aggregation pheromone of the smaller European elm bark beetle, Scolytus multistriatus (Marsham), with emphasis on information that could be used in the classroom as a practical application of organic chemistry. (Author/GA)

Presents a brief update scheme of known (CH)8 interconversions where established routes for the isomers exist, and pointing to the fact that many isomers are still unknown. (GA)

Describes the development and the composition of birth control pills. Explains the way the pill works, and other methods of contraception. (GA)

Explains the methods for reducing organic compounds using new reagents and shows their usefulness and selectivity. (GA)

Discusses some basic principles regarding why a certain inorganic element (compound) is specifically required for a certain function in biological systems. (HM)

Conflicting views have been put forward on the derivation of the distribution of solubilized molecules among micelles. This stems from failure to consider the arrangement of the solubilized molecules in the micelles. In the treatment presented enthalpy effects are ignored as they are not amenable to a simple general theory. (Author/BB)

Reported here are brief descriptions of a common grading and scaling formula for large multi-section courses, an ion exchange amino acid separation and thin layer chromatography identification experiment, a conservation of energy demonstration, a catalyst for synthesizing esters from fatty aids, and an inexpensive method for preparing platinum…

Describes a technique based on combinatorial mathematical principles for counting porphyrin isomers. (Author/CP)

The purpose of this paper is to show how symmetry selection rules can be used to determine whether certain of the electronic transitions exhibited by the title compounds are allowed or forbidden by symmetry. (Author/CP)
