The economy of the leaching reaction of magnesite mainly depends on the cost of succinic acid which may be regenerated by treating magnesium succinate with any inorganic acid thus taking advantage of selectivity without incurring cost penalties.
Dietary acidifiers (organic and inorganic acids) have been broadly applied worldwide in diets of animals in order to replace antibiotic growth promoters, because of their potential to reduce the GIT-pH, which improves nutrient digestion and protects the GIT from pathogenic bacteria invasion and proliferation (Kil et al., 2011).
Abstract Polyaniline (PANI) nanolibers were prepared by direct mixed oxidation in four kinds of inorganic acids. The characterization of scanning electron microscopy (SEM) showed that high quality PANI fibers with uniform diameter and several microns length can be obtained by direct mixed oxidation, especially in a sulfuric acid system.
Using weak organic acids as acidulants for pressure-processed foods may be advantageous in terms of their microbial destruction capabilities, when compared to strong inorganic acids.
Acid producers generate both organic and inorganic acids. For example, the bacteria Thiobacillus is an aerobic organism that produces sulfuric acid and works symbiotically and synergistically with sulfate reducers.
The method requires the use of dilute KOH as the titrant, and this reacts with a wide variety of compounds, including organic and inorganic acids, free fatty acids, esters, phenols, various salts, antioxidants, processing acids and degradation byproducts in the final biodiesel product.
In contrast, if acidosis is due to the presence of inorganic acids where the accompanying anion is not permeable to cells, such as hydrochloric, phosphoric, or sulfuric acids, hydrogen ions move into the cells alone and potassium subsequently moves out of the cells.
The system can also withstand a wide range of chemicals, such as organic and inorganic acids, alkalis and various solvents, making the product ideally suited to meet the demands in food processing facilities, meat and poultry plants.
Dust Corrosion of metal components MIC (Microbiologically Influenced Corrosion) comes from organic or inorganic acids, alkalis, or reducing agents such as hydrogen sulfide or ammonia produce byproducts that are corrosive to mild steel, stainless steel, copper alloys, or galvanized steel.
In the present work, we have synthesized polyaniline by chemical polymerization method using inorganic acids (viz.
Excellent resistance to chemical spills, including alkaline cleaning compounds and both organic and inorganic acids, ensures suitability for most food industry installations: at either the manufacturing/ processing facility, retail, catering or distribution premises.
Toxic substances of concern included asbestos (from insulation and fireproofing materials), concrete (made from Portland cement and used in the buildings' construction) and the crystalline silica it contained, CO (from fires and engine exhaust), diesel exhaust (from vehicles and equipment), mercury (from fluorescent lights), chlorodifluoromethane (Freon[TM]-22, from air conditioning systems), heavy metals (from building materials), hydrogen sulfide (from sewers, anaerobically decomposing bodies, and spoiled food), inorganic acids, volatile organic compounds (VOCs), and polynuclear aromatic hydrocarbons (PAHs) (from fires and engine exhaust).
