2,4,6-Trichloroaniline + 3 HCl The preparation of 2,4,6-trichloroaniline Safety Occupational exposure to 2,4,6-trichloroaniline may occur through inhalation and dermal contact with this compound at workplaces where 2,4,6-trichloroaniline is produced or used (SRC). The general population may be exposed to 2,4,6-trichloroaniline via drinking water and dermal contact with this compound in ...
Diagram of the mercury-cell process, showing an "inner" cell sandwiched between two "outer" cells, with a layer of mercury common to all three. In the mercury-cell process, also known as the Castner–Kellner process , the "outer" electrolytic cells each contain an anode immersed in brine, which floats on a layer of mercury.
Manufacturing process wastestreams, which can include conventional pollutants (i.e. controllable with secondary treatment systems), toxic pollutants (e.g. solvents, heavy metals), and other harmful compounds such as nutrients; Non-process wastestreams: boiler blowdown and cooling water, which produce thermal pollution and other pollutants
The sodium–mercury amalgam flows to the center cell, where it reacts with water to produce sodium hydroxide and regenerate the mercury. Mercury cell electrolysis, also known as the Castner–Kellner process , was the first method used at the end of the nineteenth century to produce chlorine on an industrial scale.
Steam distillation is a separation process that consists of distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container.
Aniline absorbs in the K (220 - 250 nm) and the B (250 - 290 nm) bands exhibited by benzenoid compounds. The K and B bands arise from π to π* transitions as a result of the a group containing multiple bond being attached to the benzene ring. When dissolved in ethanol, λ max for aniline is 230 nm, but in dilute aqueous acid λ max is 203 nm ...
N,N-Dimethylaniline (DMA) is an organic chemical compound, a substituted derivative of aniline. It is a tertiary amine, featuring a dimethylamino group attached to a phenyl group. This oily liquid is colourless when pure, but commercial samples are often yellow. It is an important precursor to dyes such as crystal violet.
Since AOPs were first defined in 1987, the field has witnessed a rapid development both in theory and in application. So far, TiO 2 /UV systems, H 2 O 2 /UV systems, and Fenton, photo-Fenton and Electro-Fenton systems have received extensive scrutiny. However, there are still many research needs on these existing AOPs.
