Consumer and other products

Given the mass of a reactant or product in a chemical reaction, use a balanced chemical equation to calculate the masses of other reactants consumed and other products formed (Section 2.4, Problems 33-46). 

The detergent range alcohols and their derivatives have a wide variety of uses ia consumer and iadustrial products either because of surface-active properties, or as a means of iatroduciag a long chain moiety iato a chemical compound. The major use is as surfactants (qv) ia detergents and cleaning products. Only a small amount of the alcohol is used as-is rather most is used as derivatives such as the poly(oxyethylene) ethers and the sulfated ethers, the alkyl sulfates, and the esters of other acids, eg, phosphoric acid and monocarboxyhc and dicarboxyhc acids. Major use areas are given ia Table 11. 

Current world production of ethylene glycol is approximately 15 billion pounds. Most of that is used for producing polyethylene terephtha-late (PET) resins (for fiber, film, bottles), antifreeze, and other products. Approximately 50% of the world EG was consumed in the manufacture of polyester fibers and another 25% went into the antifreeze. 

Flame retardants in printed circuit boards partnership. Circuit boards are commonly used in electronics in consumer and industrial products, including computers and cell phones. In order to ensure fire safety, manufacturers commonly produce circuit boards with flame-retardant chemicals. While serving an important performance function, some flame-retardant chemicals can be harmful if released into the environment. To better understand the issues and the full range of options for flame-retarding circuit boards, DfE is engaging with the electronics industry and other stakeholders in a partnership. 

The production of ort/ro-toluidine and its use as an intermediate in the production of dyes and pigments, mbber chemicals and other products may result in its release to the environment through various waste streams. The primary routes of potential human exposure to ort/ro-toluidine and its hydrochloride salt are inhalation and dermal contact. Consumer exposure may occur from residues present in commercial dyes and on textiles and via smoking (lARC, 1982 Department of Health and Human Services, 1982 Environmental Protection Agency, 1984, 1997 Department of Health and Human Services, 1999). 

Nonylphenol, a product of Union Carbide, Canada Ltd., consists of a mix of p-substituted monoalkyl nonypbenols, (randomly branched), with approximately 3% of the o-isomer and 4% dinonyl-phenol also represent. Apart from Dowanol, all the adjuvants mentioned contain minor variable amounts of undefined contaminants which are a function of the well head source and batch from which they were distilled (Aerotex, Cyclosol) or the method of synthesis (Atlox and nonylphenol). These chemicals and related compounds are also widely used in a wide range of household products including detergents, cleaners, shampoos, foods and other consumer and commercial products. 

Vinyl chloride is consumed in large quantities as a raw material to manufacture pipe, hose, wrapping, and other products fabricated from polyvinylchloride plastic. This highly flammable, volatile, sweet-smelling gas is a known human carcinogen. 

Where the bergapten (5-methoxypsoralen) content of all relevant oils present in a compound has been determined, it is recommended that for applications on areas of skin exposed to sunshine, excluding bath preparations, soaps and other products which are washed off the skin, the total level of bergapten in the consumer products should not exceed 0.0015% (15ppm). This is equivalent to 0.0075% (75 ppm) in a fragrance compound used at 20% in the consumer product. 

Two runs were done with H2 added. One was with a small amount of H2, which did not influence the reaction, to see if the H2 would be recovered. It was completely recovered after the run, showing that our finding of no H2 production was correct any H2 would have been detected if formed. The other run had 850jn of H2 added. In this case some of the H2 was consumed, and the production of O2 was enhanced. 

The carbon oxide yields and oxygen consumption were continuously monitored by gas analyzers and other products were detected and measured by gas chromatography. The major products at the tube temperatures 700, 750 and 800 K, expressed as a fractional yield of the fuel consumed, are given in Table 6.2. Approximately 25% of the fuel was consumed at its maximum, just prior to the onset of the negative temperature... 

Different types of petroleum can be used in different ways. Jet fuel differs from the gasoline that automobiles consume, for example. Refineries separate different petroleum products by heating petroleum to the point that heavy hydrocarbon molecules separate from lighter hydrocarbons so that each product can be used for a specific purpose. Refining reduces the waste associated with using limited supplies of more expensive petroleum products in cases in which a cheaper, more plentiful type of petroleum would suffice. Thus, tar or asphalt, the dense, nearly solid hydrocarbons, can be used for road surfaces and roofing materials, waxy substances called paraffins can be used to make candles and other products, and less dense, liquid hydrocarbons can be used for engine fuels.
