Chemistry 2a is an introductory course in organic chemistry. Do not let this frighten you away. For those timid and unassuming souls who shy from all things new and unexperienced, this organic stuff means only that the course has limited itself to the study of carbon and its compounds. True, there are more than a few compounds in this field. That too, should not frighten you for Professor Fieser does a splendid job of "essential plucking...
...East investigated. He found that a scar of an old ulcer partly blocked the passageway from his patient's stomach into his intestines. This stricture caused food to remain unduly long in the stomach. The food fermented and formed, along with non-inflammable carbon dioxide, highly inflammable methane (which miners know as fire damp and farmers as marsh gas) and inflammable hydrogen disulfide, the gas which makes rotten eggs smell as they...
...nitrocellulose process for making rayon was patented in 1884 by Count Hilaire de Chardonnet, who dissolved nitrocellulose in an organic solvent, forced the solution through fine holes, finally obtaining long fibres which were spun into threads (Tubize). The viscose process (treating cotton with caustic soda and carbon disulphide) was patented eight years later by two U. S. chemists. Later a third method (little used today) was found using copper hydroxide and ammonia, and still later came a fourth in which the final product is not cellulose but cellulose acetate. Viscose rayon leads in U. S. production; the costlier acetate rayon?...
Early that morning the battered, blackened barge Ready had been towed by the tug Powerful from St. George, Bermuda, to a point eight miles off lovely Nonsuch Island. Bracketed on the inside wall of the bathysphere were oxygen tanks. Trays of soda lime (to absorb exhaled carbon dioxide) and calcium chloride (to absorb moisture) were stowed in. Dr. Beebe and Mr. Barton wedged themselves in, smiling and waving. They were confident their bathysphere would stand up under the great pressure a half-mile down (1,300 lb. per sq. in.) because a few days before it had been lowered empty...
...Although not definitely proved, the evidence seems to indicate that nicotine is at least one of the toxic factors [in cigaret smoking] and that carbon monoxide and the products of the cigaret papers may be eliminated as offending mediums." Other suspect factors: "Ammonia, pyridine and pyridine derivative, cyanides and sulpho-cyanides, arsenic...
