In 2012, a study found that Corexit made the oil up to 52 times more toxic than oil alone, [12] and that the dispersant's emulsifying effect makes oil droplets more bio-available to plankton. [13] The Georgia Institute of Technology found that "Mixing oil with dispersant increased toxicity to ecosystems" and made the gulf oil spill worse. [14]
Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent.It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell [3] and sweet taste. [9]
The concept of basic chemicals is very close to chemical commodities. In fact basic chemicals are chemical substances used as a starting material for the production of a wide variety of other chemicals; for this reason they are in general commodities, because they are highly demanded. Some examples of basic chemicals are: ethylene, benzene ...
Commodity chemicals (or bulk commodities or bulk chemicals) are a group of chemicals that are made on a very large scale to satisfy global markets. The average prices of commodity chemicals are regularly published in the chemical trade magazines and web sites such as Chemical Week and ICIS .
MTBE removal from groundwater and soil contamination in the U.S. was estimated to cost from $1 billion [38] to US$30 billion, [39] including removing the compound from aquifers and municipal water supplies and replacing leaky underground oil tanks. In one case, the cost to oil companies to clean up the MTBE in wells belonging to the city of ...

After August 2002, all European Union countries became obliged to add about 6 mg/L (0.034 oz/bbl) of Solvent Yellow 124, a dye with structure similar to Solvent Yellow 56, to heating fuel.
However, for production of an essential oil extract from a plant, then quantity of CO 2 used will be a significant cost, and "complete" extraction not required, a yield of 70 - 80% perhaps being sufficient to provide economic returns. In another case, the selectivity may be more important, and a reduced rate of extraction will be preferable if ...
