2,4-Dinitrotoluene (DNT) or dinitro is an organic compound with the formula C 7 H 6 N 2 O 4. This pale yellow crystalline solid is well known as a precursor to trinitrotoluene (TNT) but is mainly produced as a precursor to toluene diisocyanate .
The oxidation of 2,4,6-tri-tert-butylphenol in the alkaline to the intensely blue-colored phenoxy radical can also occur with potassium ferricyanide. [1] [9] [6] The 2,4,6-tri-tert-butylphenoxy radical forms blue crystals on cooling to -70 °C which are stable at room temperature for several weeks and only gradually turn yellow. [9]
Thin-layer chromatography (TLC) is a chromatography technique that separates components in non-volatile mixtures. [1]It is performed on a TLC plate made up of a non-reactive solid coated with a thin layer of adsorbent material. [2]
2,4,6-Trinitrobenzoic acid (TNBA) is an organic compound with the formula (O 2 N) 3 C 6 H 2 CO 2 H. It is a high explosive nitrated derivative of benzoic acid . Preparation and reactions
A solar still distills water with substances dissolved in it by using the heat of the Sun to evaporate water so that it may be cooled and collected, thereby purifying it. They are used in areas where drinking water is unavailable, so that clean water is obtained from dirty water or from plants by exposing them to sunlight.
VAMTOX units have a system of valves and dampers that direct the air flow across one or more ceramic filled bed(s). On start-up, the system preheats by raising the temperature of the heat exchanging ceramic material in the bed(s) at or above the auto-oxidation temperature of methane 1,000 °C (1,830 °F), at which time the preheating system is ...
The filter sand takes up most space of the chamber. It sits either on a nozzle floor or on top of a drainage system which allows the filtered water to exit. The pre-treated raw water enters the filter chamber on the top, flows through the filter medium and the effluent drains through the drainage system in the lower part.
The waste waters eluted from the ion-exchange column containing the unwanted calcium and magnesium salts are typically discharged to the sewage system. [3] Recharge typically takes the following steps: [11] Backwash: Water is directed through the resin in the direction opposite to that of normal flow, and the output is sent to a drain for disposal.
