Besides of MNT, the obtained pure isomers, after isomer separation, serve as an important raw material for the dyeing industry Nitration of chlorobenzene other related industries.

Meissner MNT plants are characterized by their circulation reactors which have been developed especially for nitration purposes, and which ensure a high degree of security due to their large cooling areas for a small reactor volume.

The circulation pumps used in the reactors accomplish an optimum conversion of the reactants, in this way providing a constantly high quality of MNT.

For safety reasons, the separation of the mixture of Nitration of chlorobenzene isomers from the spent acid is performed in dynamic separators, which are characterized by a short separation time within the range of seconds and a very small volume.

The MNT isomer mixture is automatically conveyed to the washing section consisting of compact Meissner washing apparatuses performing the washing as well as the separation of the product from the washing medium.

Additionally to the MNT plant, Meissner as main contractor also offers the spent acid regeneration plant performing the recovery of concentrated Sulfuric Acid and Nitric Acid, as well as the respective plant for MNT isomer separation and an economical waste water purification plant for the removal of toxic nitrocresols, contained in the MNT waste water, in order to obtain a biologically degradable waste water.

Dinitrotoluene DNT The mixture of Dinitrotoluene isomers is a very valuable raw material for the plastics chemistry, which after hydrogenation to TDA and subsequent phosgenation to TDI is finally processed to polyurethane.

DNT plants by MEISSNER are characterized by their circulation reactors, which have been developed especially for nitration purposes, and which ensure a high degree of security due to their large cooling areas with small reactor volumes.

The circulation pumps used in the reactors provide for an optimum conversion of the reactants and thus a DNT of uniformly high quality. After each nitration step the product is separated from the respective acid in dynamic separators and is then further processed.

The raw DNT is automatically conveyed to the washing unit consisting of MEISSNER compact washing apparatus, which perform the product washing as well as the separation of the product from the respective washing medium.

Organochlorides

Additionally to the DNT plant, MEISSNER as main contractor also offers the spent acid regeneration plant performing the recovery of concentrated Sulphuric Acid with recovery of Nitric Acid and organics, as well as an economical waste water treatment plant for the disposal of toxic nitrocresols contained in the DNT waste water so that a biologically degradable waste water is obtained.

Mononitrobenzene MNB Mononitrobenzene, obtained from Benzene and Nitric Acid in the presence of Sulfuric Acid by the adiabatic process, is the starting material for Aniline, which is a valuable raw material for the plastics chemistry MDI, polyurethane and the dyeing chemistry Aniline derivatives.

Adiabatic nitration MNB plants by MEISSNER are characterized by the application of tube reactors, which minimize the formation of by-products Nitrophenols, Picric Acid and Dinitrobenzene by optimum reactant intermixing and negligible back mixing inside the tube reactor.

Due to the adiabatic technology, the reconcentration of the Sulfuric Acid accruing after separation of the MNB takes place directly in the plant. The crude Mononitrobenzene is automatically fed to the washing section consisting of MEISSNER compact washers, which perform the product washing as well as the separation of the product from the respective washing medium.

In the subsequent stripping unit the residual Benzene still contained in the purified Mononitrobenzene is separated by means of steam and returned into the process. Mononitrochlorobenzene MNCB The mixture of Mononitrochlorobenzene isomers, obtained from Chlorobenzene and Nitric Acid in the presence of Sulphuric Acid by the adiabatic process, or from Chlorobenzene and the corresponding mixed acid by the conventional nitration process, serves for obtaining the separate isomers.

These are mainly used as raw materials in the dyeing chemistry and the agricultural chemistry.

Haloarenes with concentrated HNO 3 in the presence of concentrated H 2 SO 4. Sulphonation. is chlorobenzene, an aryl halide because the chlorine is directly attached to the benzene ring.

(a), is benzyl chloride which is a substituted haloarene, while (b) is chlorocyclohexane. The rate of heterogeneous sulphonation of chlorobenzene in sulphuric acid solutions of different concentrations has been found to increase with amount and concentration of acid used, and with increase of temperature.

No appreciable amount of sulphone was formed under the conditions used. Nitration of toluene and chlorobenzene Successful regioselective nitration of phenol has prompted us to extend the nitration studies to toluene (weakly activating and o-/p-orienting).

enhanced the para-selectivity of chlorobenzene nitration by using nitric acid as nitrating agent, up to an ortho-para isomer ratio in product distribution of chlorobenzene mono- nitration, and the yield of chlorobenzene mononitration.

Nitration. When benzene is benzene chlorobenzene. chlorobenzene o-dichlorobenzene p-dichlorobenzene Thus the reactivity of benzene ring towards electrophilic substitution reactions increases. The substituents or groups which direct the incoming group to meta position are called meta directing groups.
