Energy The capacity for doing work Vanous forms include chemical energy, nuclear energy, kinetic energy and others Esters Organic compounds which may be made by interaction between an alcohol and an acid, and by other means Esters are noniomc compounds, including solvents and natural fats Ethane C2H6 A paraffinic hydrocarbon derived from petroleum or natural gas, im portant for organic synthesis Ethylene is derived from it Ethyl alcohol or ethanol C2HsOH Organic compound synthesized either from petroleum or natural gas or denved by a fer mentation process Wide use as a solvent and for chemical synthesis expand and contract greatly in response to changes in temperature and pressure, easily diffuses into other gases, readily and uni formly distributes itself throughout any con tainer Glycerol A clear, sweet, colorless, syrup-like liquid (solid at lower temperatures) denved in various ways by-product of soap manufacture, by fermentation or synthesis Used in medicines, soaps, antifreeze, as a solvent, or reagent and as humectant m foods and tobacco, to make explosives High energy FUEL or (HEF) Liquid or solid chemical propellant providing more energy than conventional fuels Vanous chemical fuels used in U S rocket and mis sile programs, e g, hydrocarbons, hydrogen, hydrazine, aniline, etc Ethylene C,H< Caseous olefinic com pound resulting from the cracking of either selected petroleum fractions or natural gas Wide use as starting material for numerous chemical reactions, notably manufacture of polyethylene and related plastics materials Ethylene glycol Clear, colorless, liquid Useful as humectant because it ab sorbs approximately twice its weight of water at room temperature and 100 per cent hu midity A major use antifreeze Among many other uses dye solvent, solvent for resins, drugs, other organic chemicals Highly toxic if ingested Fertilizer Plant food usually sold in mixed formula containing basic plant nu trients compounds of nitrogen, potassium, phosphorus, sulfur, and sometimes other minerals Flotation reagent Chemical used m flotation separation of minerals Added to pulverized mixture of solids and water and oil, it causes preferential nonwetting by water of certain solid particles, making possible the flotation and separation of unwet particles Gas A state of matter in which the ma terial has very low density and viscosity, can Hydrocarbons Organic compounds, composed solely of carbon and hydrogen Several hundred thousand molecular com binations of C and H are known to exist Basic building blocks ofall organic chemicals Main chemical industry sources of hydrocar bons are petroleum, natural gas and coal Hydrometallurgy Science of metal recovery by a process involving treatment of ores m an aqueous medium, such as acid or cyanide solution Inhibitor An agent which arrests or slows chemical action or a material used to prevent or retard rust or corrosion InorcaniC Term used to designate com pounds that generally do not contain car bon Source matter, other than vegetable or animal Examples sulfuric acid and salt Exceptions are carbon monoxide, carbon dioxide Intermediate A chemical formed as a "middle-step" m a senes of chemical reac tions, especially m the manufacture of or ganic dyes and pigments In many cases, it may be isolated and used to form a variety of desired products In other cases, the inter mediate may be unstable or used up at once 1425
