40 – 60 % propene is used for the manufacture of 2-propanol. A large number of catalysts for 2-propanol dehydrogenation have been studied‚ including copper‚ zinc‚ and lead metals‚ as well as metal oxides‚ e.g.‚ zinc oxide‚ copper oxide‚ chromium-activated copper oxide‚ manganese oxide‚ and magnesium oxide. Inert supports‚ such as pumice‚ may be used. CH3CH=CH2 CH3CH(OH)CH3 CH3COCH3 +H2 (3) By catalytic oxidation of Propene (Wacker-Hoechst). The process is analogous

acidic presents two different problems for crops. First‚ the amount of necessary minerals in the soil such as potassium and calcium decreases. Second‚ aluminum and manganese levels increase to potentially toxic levels below a pH of roughly 5.5.Calcium oxide‚ addresses the problem. It reacts in water to release calcium ions and hydroxide ions‚ which raise the pH of the soil.The soil which is too acidic will be neutralised by the lime which is alkaline. H2O + CO2 -> H2CO3 2SO2 + H2O + O2 -> 2H2SO4

ANTACIDS- Classification and Mechanism of Action INTRODUCTION Antacids are defined as a substance‚ generally a base‚ which counteracts stomach acidity. The name antacid means anti-acid (against acid). Antacids are the primary treatment for ailments such as gastric reflux‚ gastritis‚ upset stomach and heartburn. Hydrochloric acid is secreted by the stomach to kill harmful organisms‚ aid digestion and activate digestive enzymes. Excess secretion of acid into stomach or impaired resistance by

40 Common Minerals and Their Uses Aluminum The most abundant metal element in Earth’s crust. Aluminum originates as an oxide called alumina. Bauxite ore is the main source of aluminum and must be imported from Jamaica‚ Guinea‚ Brazil‚ Guyana‚ etc. Used in transportation (automobiles)‚ packaging‚ building/construction‚ electrical‚ machinery and other uses. The U.S. was 100 percent import reliant for its aluminum in 2012. Barium A heavy metal contained in barite. Used as a heavy additive in oil

used to reduce these. 1. Extraction costs:-Affected by depth‚ overburden quality‚ drainage problems‚ size of deposit. 2. Processing costs :-The cost of extracting a metal depends upon the other elements with which it is combined.eg aluminium is most abundant in clay but can only be economically extracted from bauxite 3. Purity 4. The financial cost‚ energy required and quantity of ore-bearing rock extracted all increase rapidly as ore purity decreases. 5. Land conflicts:-Competing
