Magnesium nitrate exists in multiple forms differentiated by the degree of hydration e.g. dihydrate, tetrahydrate and hexahydrate. Sasol Nitro in South Africa is a major manufacturer of magnesium nitrate hexahydrate and produces and exports about 25 % of the estimated world production of 20 kilo tonnes per year. The hexahydrate of magnesium nitrate is solely supplied to the agricultural sector where it is used in fertilizers and, principally, in fertigation (liquid fertilizers). See annex A for the Technical Data Sheet. Discussion The TNO Prins Maurits Laboratory in The Netherlands and the Fire Engineering Laboratory of the South African Bureau of Standards tested the magnesium nitrate hexahydrate in accordance with Test 0.1: Test for oxidizing solids of the UN Manual of tests and criteria. The results obtained are given in the table below.

This article is published with open access at Springerlink.com Abstract: In the present investigation, the nano- and micro-sized powders were synthesized by stoichiometric contents of magnesium and aluminum nitrates using combustion–oxidation method. The study was conducted over a wide range of operating conditions, in terms of fuel ratio and calcination temperature. The characteristics of magnesium aluminate powders were studied by differential thermal analysis and thermogravimetry (DTA–TG), Brunauer–Emmett–Teller (BET), X-ray diffraction (XRD), and transmission electron microscopy (TEM) techniques. The thermal stability of powders was evaluated by calcination at different temperatures. Differences of the specific surface areas were related to the composition and crystallite size. The importance of fuel ratio and calcination temperature to achieve the nano- and micro-sized oxide was discussed in detail. The fuel ratio of 0.56 and calcination at 800 ℃ provided the conditions to achieve the nano-scale magnesium aluminate powders, smaller than 20 nm. The application of presented algorithm can be an important tool for control of particle size in the nano- and micro-scale.

  • Nitric Acid Concentration Dilute Nitric Acid Can Be Concentrated by Evaporation of the Water from the Mixture
    Both the single step evaporators and the distillation process utilize the Chemetics natural Nitric Acid circulation thermosyphon evaporators that have proven to be extremely reliable and easy to Concentration operate. Gravity flow is used to transport the hot nitric Nitric acid is used in a wide variety of chemical acid between the different concentration steps processes. Concentration of nitric acid is wherever possible to improve plant safety. complicated by the fact that nitric acid has a maximum azeotrope at ~67wt% as shown in the chart below. Weak Nitric Acid Concentration Dilute nitric acid can be concentrated by evaporation of the water from the mixture. The maximum concentration that can be achieved for this two-component distillation process is the azeotrope concentration of ~67 wt%. Depending on the application Chemetics offers the following processes: ■ Single step concentration under vacuum for product concentrations below 25 wt% ■ Nitric Acid Distillation at atmospheric pressure for product concentrations up to 67wt% ■ Double effect concentration systems with improved energy consumption combining the single step vacuum concentration unit with the atmospheric distillation unit. This process is expecially suitable for concentration of very dilute or very large streams of nitric acid. Heat integration (feed/product interchangers) and high efficiency distillation tower packing (to minimize the amount of reflux) are used to reduce the energy requirements of the system. Spent nitric acid streams containing Nitrous Acid (HNO2) or NOx are pre-treated in a purification column upstream of the concentration system. The NOx vapours from this column can be recovered as additional nitric acid using a NOx absorber. Further options to remove other impurities (e.g.
