Exporting chemicals

A larger number of features are provided by the ACDStructure Drawing Applet (ACDLabs). Both structures and reactions can be drawn, imported, and also exported. This applet supports Molfiles and has a large, integrated collection of pre-defined templates, which are extensible by the user. Additionally, gif files can be exported. It is not possible to draw or to Lmport/export chemical reactions. 

REACH will bring multiple benefits in terms of health, the environment, but also to industry in the EU and to countries to which the EU exports chemicals and related products. For instance, exports of substances that have been subject to the requirements under REACH will have benefits for consumers in... 

Export Sales. Chemicals used in the export trade are, of course, consumed in foreign countries in the same categories just discussed. However, exported chemicals are in a special class because, regardless of their use in the foreign country, they are removed from the channels of trade in the United States. 

The directory is the only updated compendium of its kind with a global perspective. It is of great value to governments world-wide, health and environment authorities, legal experts, those who impcMt and export chemicals, information workers and many others. 

The MITI/MHW [14] and MOL laws are of primary concern to non-Japanese manufacturers who export chemicals to Japan, and the former will be discussed here. 

Colchicine has a narrow therapeutic index (i.e., the amount of drug that produces the desirable therapeutic effect is not much lower than the amount that produces an adverse effect). Its therapeutic effect depends on inhibiting tubulin synthesis in neutrophils, but it can also prevent tubulin synthesis (and, thus, cell division and other cellular processes) in other cells. Fortunately, neutrophils concentrate colchicine, so they are affected at lower intakes than other cell types. Neutrophils lack the transport protein P-glycoprotein, a member of the ABC cassette family (which includes the CFTR channel). In most other cell types, P-glycoprotein exports chemicals such as colchicine, thus preventing their accumulation. 

Chemicals and Dyes. Practically every chemical being used is produced within India, some in small quantities, others in large. India also has the capacity to export chemical plants, on a turnkey basis, for such materials as sulfriric acid, caustic soda, soda ash, and fertilizer. In the following discussion, the history of two chemicals, once in great demand from India and which are no longer produced, will be set forth as well as three whose production rate is continuously growing. 

The PubChem download service exports chemical structure images. The images are either 300 x 300 or 100 x 100 pixels in size. The image format is PNG and images are packaged as SID or CID-numbered files in a zip (.zip) archive. 

F] or substances to qualify as solely for export chemicals, their manufacture and processing must be limited to activities which do not involve use, except in small quantities solely for R D in accordance with 40 CFR 720.36. Blending into a finished product does not involve use. However, the use of a new chemical substance as an intermediate in the chemical production of another chemical substance would require reporting of the intermediate. ... 

As discussed in Chapter 8, Exports and Imports, 12(b) of the Toxic Substances Control Act (TSCA) requires exporters to notify the Environmental Protection Agency (EPA) before exporting chemicals for which data are required under 4 or 5(b), an order has been issued under 5, a rule has been proposed or issued under section 5 or 6, or an action is pending or relief has been granted under 5 or 7. For exports to be in compliance with 12(b), the Company needs to ensure that the people who are in a position to develop the information showing which products contain chemicals subject to these TSCA provisions make that information available to the employees exporting the products in a timely manner. 

Demarches, none the less, had their limitations. Former officials of the Reagan administration acknowledged that many of their demarches failed. In January 1990 Kenneth Adelman asserted that The Germans have been a big problem. I personally talked to them five or six years ago about exporting chemicals to the bad guys. They never really took it seriously The Schauble report confirmed that there had been a stream of representations to Bonn about the involvement of German companies in the... 

Chem3D can read a wide variety of popular chemical structure files, including Gaussian, MacroModel, MDL, MOPAC, PDB, and SYBYL. Two-dimensional structures imported from ChemDraw or ISIS/Draw are automatically converted to three-dimensional structures. The Chem3D native file format contains both the molecular structure and results of computations. Data can be exported in a variety of chemical-structure formats and graphics files. 

Molden can display molecular geometries in a variety of formats, including lines, tubes, ball and stick, ribbons, and CPK. The user has some control over colors and sizes. Molden also has features designed for the display of proteins and crystal structures. The display can be exported as postscript, VRML, Povray, and image files. It can also be configured as a chemical mime viewer. 

Molden now has the capacity to export a series of GIF files, creating an additional file with each screen update. Third-party utilities can be used to combine these images in animations with various file formats, including fii and animated GIF files. This is one of the easiest ways to create animations of chemical systems. 

Acetic anhydtide is a mature commodity chemical ia the United States and its growth rate in the 1970s and 1980s was negative until 1988 when foreign demand neatly doubled the exports of 1986. This increase in exports was almost certainly attributable to the decline in the value of the U.S. doUar. Over four-fifths of all anhydtide production is utilized in cellulose acetate [9004-35-7] manufacture (see Cellulose esters). Many anhydtide plants are integrated with cellulose acetate production and thus employ the acetic acid pyrolysis route. About 1.25 kg acetic acid is pyrolyzed to produce 1.0 kg anhydtide. 

Anhydride has been used for the illegal manufacture of heroin [561-27-3] (acetyknorphine) and certain other addictive dmgs. Regulations on acetic anhydtide commerce have long been a feature of European practice. After passage in 1988 of the Chemical Diversion and Trafficking Act, there is also U.S. control. Orders for as much as 1,023 kg acetic anhydtide, for either domestic sale or export, require a report to the Department of Justice, Dmg Enforcement Administration (54). 

Adipic acid is a very large volume organic chemical. Worldwide production in 1986 reached 1.6 x 10 t (3.5 x 10 lb) (158) and in 1989 was estimated at more than 1.9 x 10 t (Table 7). It is one of the top fifty (159) chemicals produced in the United States in terms of volume, with 1989 production estimated at 745,000 t (160). Growth rate in demand in the United States for the period 1988—1993 is estimated at 2.5% per year based on 1987—1989 (160). Table 7 provides individual capacities for U.S. manufacturers. Western European capacity is essentially equivalent to that in the United States at 800,000 t/yr. Demand is highly cycHc (161), reflecting the automotive and housing markets especially. Prices usually foUow the variabiUty in cmde oil prices. Adipic acid for nylon takes about 60% of U.S. cyclohexane production the remainder goes to caprolactam for nylon-6, export, and miscellaneous uses (162). In 1989 about 88% of U.S. adipic acid production was used in nylon-6,6 (77% fiber and 11% resin), 3% in polyurethanes, 2.5% in plasticizers, 2.7% miscellaneous, and 4.5% exported (160). 

TuU Chemical Co. (Oxford, Alabama) is the only producer of sodium fluoroacetate. It is sometimes colored with the black dye nigrosine. It is usually packed in 8 oz (227 g) or 5 kg cans and is almost exclusively exported. There is very limited use in the United States.

Primary consumers for ferrous scrap are the iron and steel mills and foundries. Minor consumers iaclude ferroalloy producers, copper producers for use ia copper precipitation (see Recycling, nonferrous metals), and the chemical iadustry. The steel iadustry consumes about three-fourths of the total. Scrap consumption for ferroalloy production, copper precipitation, and the chemical iadustry total less than one million t. The United States is the leading exporter of ferrous scrap, exporting almost nine million t ia 1994, valued at about 1.3 biUioa. Total value of domestic scrap purchases and exports ia 1994 was 8 biUioa (2). 

Economic Aspects. Celestite is mined and then shipped to countries where chemical processing takes place. Spain is the largest celestite-exporting country, as almost all of its output is exported. Mexico is the next largest exporter. About half of its annual output is exported. Most of celestite production from Turkey and Iran is also exported. Iranian exports are beheved to be shipped to the CIS and other Eastern European countries.
