Chemistry Example

Charbroiled Chemicals has one facility adjacent to an industrial park on the outskirts of the city. The facility manufactures a range of products in 200 to 1000 gal batch reactors by chlorinating various organic feed materials. The reaction products go through several purification stages, with the chlorinated organic products sealed and labeled in 55 gal drums for delivery to customers. Byproducts that cannot be recycled are neutralized and stabilized in the waste treatment facility prior to disposal. 

The Questions in these worked examples refer to the twelve questions in Chapter 3. Question 1 ( Is intentional chemistry performed at your facility ) should be answered YES for this example, since raw materials are processed such that a chemical reaction is intended to take place. Products are of a different chemical composition than the starting materials. Intentional chemistry is also likely being practiced in the waste treatment facility. 

Question 5 ( Is combustion with air the only chemistry intended at your facility ) should be answered NO, since the intentional chemistry involves chlorination reactions. The Note in Section 3.1 pertains to this pro- 

Rarified Research operates a ram-fed incinerator for destruction of select wastes at its large, centralized research facility, including liquid flammable solvents in small plastic containers. The incinerator is fired by natural gas and is brick-lined. Temperatures are closely monitored, and stack emissions are routinely sampled. 

Referring to the questions in Chapter 3, Question 1 ( Is intentional chemistry performed at your facility ) should be answered YES for this example.

While metal-nitrogen and metal-oxygen bonded compounds dominate nucleobase coordination chemistry, examples in which metal-carbon bonds are formed have been identified. Early studies on the synthesis of metal-labeled DNA demonstrated that nucleotide-triphosphates, UTP, CTP, dUTP, and dCTP, can undergo mercury modification at C5 (82,83). The UTP derivative was also shown to act as a substrate for RNA polymerase in the presence of mercaptans (83). Later, guano-sine was shown to undergo mercury modification at C8 though, in this case, the purine was multiply substituted, 21 (84).

Analytical chemistry spans a wide range of applications when compared to many other fields of measurement. This breadth of applications means that different aspects of sound metrological practice may have more or less importance depending on particular circumstances. Traceability [1,2], and ultimately accuracy, are two such considerations that have quite variable importance to analytical chemistry. Examples can be cited where trace-ability has no importance. Counterexamples can also be given where it is useless to perform an analytical measurement without establishing a firm link of traceability.

Model systems have been developed for many of these ion-transport mechanisms in the context of bioorganic chemistry. Examples are the cyclic peptides, described by M. R. Ghadiri et al., that have antibiotic activity similar to that of ionophores, a property that is most probably caused by the ability of these peptides to self-assemble inside biological membranes into channels [1], Other compounds able to induce the formation of membrane pores are the bouquet-molecules introduced by J.-M. Lehn [2]. Artificial / -barrels have been developed by S. Matile s group [3]. Many host molecules used in bioorganic chemistry can serve as carriers for ions across membranes and have even made possible the development of systems with which active ion transport can be achieved [4]. 

The purpose of the present review is to familiarize organic chemists with the methods of research used by radiation chemists and to point out how these methods have been and can be used for studies in physical organic chemistry. Examples which characterize the various approaches are taken mostly from the literature of the last four to five years. Summaries of earlier studies have appeared in several books and reviews on the various aspects of radiation chemistry.
