Applications in commerce

Potassium ferrocyanide finds application in commerce in the manufacture of Prussian blue, and also for case-hardening of steel.6... 

Acetic anhydride is a useful solvent in certain nitrations, acetylation of amines and organosulfur compounds for rubber processing, and in pesticides. Though acetic acid is unexceptional as a fungicide, small percentages of anhydride in acetic acid, or in cold water solutions are powerful fungicides and bactericides. There are no reports of tliis application in commerce. It is possible that anhydride may replace formaldehyde for certain mycocidal applications. 

Most polymer blends, grafts, blocks, and IPNs exhibit phase separation, as discussed previously. It must be emphasized that their wide application in commerce arises largely because of the synergistic properties exhibited by these materials. Applications have included impact-resistant plastics, thermoplastic elastomers, coatings, and adhesives. 

Grains and seeds were the progenitors of NIRS application in commerce and industry. The first nonacademic applications were made to grain, specifically to wheat. Since those days, the embryo has grown into a lusty child, and NIR technology has become a household word, to the extent that most of the world s wheat of commerce is tested rapidly and accurately for protein and moisture contents by NIRS instruments. 

Approved techniques for manual and mechanical sampling are often documented for various commodities handled in commerce by industiy groups. Examples are the International Standards Organization (ISO), British Standards Association (BSA), Japan Institute of Standards (JIS), American Society for Testing Materi s (ASTM), and the Fertihzer Institute. Sampling standards developed for use in specified industry applications frequently include instructions for labora-toiy work in sample preparation and analysis—steps (2) and (3) above. 

This is an on-going project aimed at examining the T/D characteristics of metals and alloys in a marine medium in seven- and twenty eight-day tests. The data obtained to date on seven-day tests of cuprous oxide (Cu20) and nickel metal powder (Ni) provides useful comparisons with those reported earlier for the freshwater OECD 203-based media at pH 6 and 8 (Skeaff Hardy 2005) and insight into the behaviour of metal-bearing substances used in commerce under marine conditions of the T/DP. The data supports an approach directed to the eventual adaptation, validation and application of the OECD T/DP to marine systems for the purposes of marine hazard classification of metals, metal compounds and alloys. 

The first known mention of rubber is found in the 1511 writings of Pietro Martyre d Anghiera, but until the late Eighteenth Century, it remained pretty much a curiosity item. Its name, rubber, came from the discoverer of oxygen, Joseph Priestly, who reported in 1770 using it to "rub out" black pencil marks. But its application in large scale commerce was not practical until much later. 

Finally, the Cooperative contends that we should construe the Controlled Substances Act to include a medical necessity defense in order to avoid what it considers to be difficult constitutional questions. In particular, the Cooperative asserts that, shorn of a medical necessity defense, the statute exceeds Congress Commerce Clause powers, violates the substantive due process rights of patients, and offends the fundamental liberties of the people under the Fifth, Ninth, and Tenth Amendments. As the Cooperative acknowledges, however, the canon of constitutional avoidance has no application in the absence of statutory ambiguity. Because we have no doubt that the Controlled Substances Act cannot bear a medical necessity defense to distributions of marijuana, we do not find guidance in this avoidance principle. Nor do we consider the underlying constitutional issues today. Because the Court of Appeals did not address these claims, we decline to do so in the first instance. 

Constituents. Complex halogenated organic compounds have been widely used in commerce in the last fifty years. Representative examples are pentachlorophenol, (2,4-dichlorophenoxy)aoetate, DDT and polychlorinated biphenyls (PCBs). They may not seem a good target for bioreme-diation but some successful applications have been developed. 

VINYL CHLORIDE POLYMERS. Poly(vinyl chloride) (PVC), commanding large and broad uses in commerce, is second in volume only to polyethylene, having a volume sales in North America in 1995 of 6.2 x 109 kg(13.7 x 109 lb). Vinyl compounds usually contain dose to 50% chlorine, which not only provides no fuel, but acts to inhibit combustion in the gas phase, thus supplying the vinyl with a high level of combustion resistance, useful in many building as well as electrical housings and electrical insulation applications.

The variations in isotopic composition of many elements in samples of different origin limit the precision to which a relative atomic mass can be given. The standard atomic weights revised biennially by the IUPAC Commission on Atomic Weights and Isotopic Abundances are meant to be applicable for normal materials. This means that to a high level of confidence the relative atomic mass of an element in any normal sample will be within the uncertainty limits of the tabulated value. By normal it is meant here that the material is a reasonably possible source of the element or its compounds in commerce for industry and science and that it has not been subject to significant modification of isotopic composition within a geologically brief period [43]. This, of course, excludes materials studied themselves for very anomalous isotopic composition. 

Pesticides occur in detectable amounts throughout the environment in virtually all inhabited areas of the world and in some, if not all, of the uninhabited portions. If our methods of detection were sufficiently sensitive and definitive, there is no part of the earth where we could not now find at least a few molecules of many pesticides in plants, man, animals, soil, water, and air. Pesticides are introduced into the environment in a variety of ways, including direct application in agriculture, in forest pest control, and for control of pests affecting human health. Comparatively small areas of the world are so treated, but transport by unnd, water, and movement of food and feed in commerce results in universal distribution of minute amounts of these compounds. 

Naphthazarin has recently been introduced into commerce as Alizarin Black. The commercial product is the bisulphite compound, and finds its principal application in printing. For this purpose it is mixed with chromium acetate. On steaming the bisulphite compound is decomposed, and the naphthazarin combines with the chromic oxide to form a firmly adhering lake. 

Dyestuffs of a very pure blue shade are formed by the action of oxalic acid or of hexachloride of carbon (CjClj) on diphenylamine. On a large scale diphenylamine blue is prepared by heating diphenylamine with oxalic acid to 110°-120°. The dyestuff formed, which amounts to only 10 per "cent, of the diphenylamine employed, is purified by repeated treatment with alcohol. It comes into commerce in the form of its higher sulphonic acids (soluble blue), and finds its principal application in silk- and cotton-dyeing.
