Chemical manufacturing, chemicals used

Chemical Manufacturing. Chemical manufacturing accounts for over 50% of all U.S. caustic soda demand. It is used primarily for pH control, neutralization, off-gas scmbbing, and as a catalyst. About 50% of the total demand in this category, or approximately 25% of overall U.S. consumption, is used in the manufacture of organic intermediates, polymers, and end products. The majority of caustic soda required here is for the production of propylene oxide, polycarbonate resin, epoxies, synthetic fibers, and surface-active agents (6). [Pg.518]

Although a few simple hydrides were known before the twentieth century, the field of hydride chemistry did not become active until around the time of World War II. Commerce in hydrides began in 1937 when Metal Hydrides Inc. used calcium hydride [7789-78-8J, CaH2, to produce transition-metal powders. After World War II, lithium aluminum hydride [16853-85-3] LiAlH, and sodium borohydride [16940-66-2] NaBH, gained rapid acceptance in organic synthesis. Commercial appHcations of hydrides have continued to grow, such that hydrides have become important industrial chemicals manufactured and used on a large scale. [Pg.297]

The use of scrap tires in industrial faciUties is also a potential growth market. Perhaps the best known user in this category is Archer-Daniels-Midland Company (Decatur, Illinois). Another industrial user, Elexsys (Sauget, Illinois), uses energy derived from its use of IDE as a supplemental fuel to manufacture chemicals used in the mbber industry. [Pg.13]

Designing and Operating Safe Chemical Reaction Processes (HSE 2000). Published by the U.K. Health and Safety Executive and directed to small to medium-sized chemical manufacturing companies using batch and semi-batch processes. It addresses chemical reaction hazards and inherently safer processes, hazards assessment, preventive and protective measures, and management practices. [Pg.25]

Perhaps the most important point about dioxin pollution is that it has become a normal (although certainly not desirable) consequence of many chemical manufacturing processes used in many countries today. A 1999 report on dioxins from the WHO concluded "Dioxins are found throughout the world in practically all media, including air, soil, water, sediment, and food, especially dairy products, meat, fish and shellfish. The highest levels of these compounds are found in some soils, sediments and animals. Very low levels are found in water and air." In other words, people around the world are regularly being exposed to some level—albeit small—of a very hazardous class of compounds. [Pg.177]

This burden can be considerable, as illustrated by the example given by Colborn et al (1996, p228) of the redesign of a line of upholstery fabric so that the manufacturing process and the final product were free of hazardous chemicals 7500 chemicals used to dye or process fabrics had to be surveyed. [Pg.172]

Commercial applications of hydrides have become important and some of these compounds have become industrial chemicals manufactured and used on a large scale. [Pg.795]

Furfural (1), derived from annually renewable agricultural byproducts, is an important industrial chemical manufactured and used throughout the world. It is the feedstock for a number of derivative chemicals generically known as furans -the structural characteristic of which is the five-membered oxygen-containing heterocyclic ring. Furfuryl alcohol (2) is the most important derivative of commerce, where it is used primarily in synthesis of adhesive polymers. [Pg.405]

SBG. Abbreviation for standard battery grade, highly purified chemicals manufactured for use in the battery industry. [Pg.1108]

Unlike biological systems, chemical manufacturing can use solvents other than water. The interior of an ion exchanger is a highly polar medium that strongly prefers the more polar solvent strongly from a mixture [42,43]. Containing a more polar solvent mixture, the bead then attracts polar reactants in preference to less polar ones, and so boosts their rate [44,45]. [Pg.296]

Polymers are important. Approximately 60 million tonnes are made annually. Indeed most of the organic chemicals manufactured are used to make polymers. These chemicals obviously include monomers, but indirectly the polymer industry consumes enormous quantities of organic materials for solvents, antioxidants, stabilizers, plasticizers etc. Apart from fuel (for transport and heat) and speciality chemicals like ethylene glycol (anti-freeze), pharmaceutical and agrochemicals etc., it can be stated that the end-use of most organic chemicals is in the production, directly or indirectly, of polymers. [Pg.3]

The critical provisions of these regulations related to the control of chemical manufacture and use are discussed below. [Pg.81]
