The U.S. Environmental Protection Agency (EPA) prohibits disposing of certain materials down drains. [4] Therefore, when hazardous chemical waste is generated in a laboratory setting, it is usually stored on-site in appropriate waste containers, such as triple-rinsed chemical storage containers [5] or carboys, where it is later collected and disposed of in order to meet safety, health, and ...
Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. Specifically, acetonitrile is fed into the top of a distillation column filled with hydrocarbons including butadiene, and as the acetonitrile falls down through the column, it absorbs the butadiene which is then sent from the bottom of the tower to a second separating tower.
Requirements for LLW disposal sites have been established by the NRC and use a series of natural and engineered barriers to prevent any radioactive waste from escaping into the environment. [3] Currently, the United States has four low-level waste disposal facilities that accept various levels of LLW, all are located in agreement states. [11]

In fact, the 2008–2009 acetonitrile shortage was caused by a decrease in demand for acrylonitrile. [10] 2 CH 3 −CH=CH 2 + 2 NH 3 + 3 O 2 → 2 CH 2 =CH−C≡N + 6 H 2 O. In the SOHIO process, propylene, ammonia, and air (oxidizer) are passed through a fluidized bed reactor containing the catalyst at 400–510 °C and 50–200 kPa g. The ...
Gold(III) chloride was first prepared in 1666 by Robert Boyle by the reaction of metallic gold and chlorine gas at 180 °C: [1] [6] [7] 2 Au + 3 Cl 2 → Au 2 Cl 6. This method is the most common method of preparing gold(III) chloride. It can also be prepared by reacting gold powder with iodine monochloride: [5] 2 Au + 6 ICl → 2 AuCl 3 + 3 I 2
With excavation now complete after four year of work, researchers plan to study a hoard that features gold coins minted between 364 A.D. and 408 A.D. depicting the profiles of nine different Roman ...
The Newport Chemical Depot, previously known as the Wabash River Ordnance Works and the Newport Army Ammunition Plant, was a 6,990-acre (28.3 km 2) bulk chemical storage and destruction facility that was operated by the United States Army.
