General: Acetylene is simplest member of unsaturated hydrocarbons called alkynes or acetylenes. Most important of all starting materials for organic synthesis. Usefulness of actylene is partly due to the variety of addition reactions which its triple bond undergoes and partly due to the fact that its weakly acidic hydrogen atoms are replaceable by reaction with strong bases to form acetylide salts.
Description: Ammonia is the compound formed by the chemical combination of the gaseous elements nitrogen and hydrogen. In the molar proportion of 1 part nitrogen and 3 parts hydrogen. This relationship is shown in the chemical symbol for ammonia, NH3. On a weight basis, the ratio is 14 parts nitrogen and 3 parts hydrogen or approximately 82% nitrogen and 18% hydrogen. The term ammonia as used throughout this monograph is the name of the chemical compound, NH3, which is commonly called anhydrous ammonia, Anhydrous means "without water" and when used with ammonia Indicates that the water content is less than 0.2%.
Description: Argon belongs to the family of inert, rare gases of the atmosphere. It is plentiful compared to the other rare atmospheric gases; 1 million ft3 (28,300 m3) of dry air contains 9,340 ft3 (264 m3) of argon. Argon is colorless, odorless, tasteless, and nontoxic. It is extremely inert and forms no known chemical compounds, It is slightly soluble In water.
Description: Carbon dioxide is a compound of carbon and oxygen In proportions by weight of about 27.3 A gas at atmospheric temperatures and pressures, carbon dioxide is colorless, odorless, and acid gas, it is considered y some people to have a slightly pungent odor and biting taste.
Description: Ethylene is a colorless, flammable gas with a faint odor that is sweet and musty. it is nontoxic and has been used as an anesthetic. The hazardous properties of ethylene are it flammable and its potential to cause asphyxia by displacement of air with the resultant lowering of the oxygen content below that necessary to support life.
Description: Hydrogen is colorless, odorless, tasteless, flammable, and nontoxic. It exists as a gas at ambient temperatures and atmospheric pressures. It is the lightest gas known, with a density approximation of 0.07% that of air. Hydrogen is present in the atmosphere occurring in only concentrations of about 0.5 ppm by volume at lower altitudes. Hydrogen burns in air with a pale blue, almost invisible flame. ..Read More..
Description: After hydrogen, helium is the lightest element and has the smallest molecular cross-section of any gas. Helium Is one of the rare gases in our earth's atmosphere in which it is present in a concentration of 5 ppm. It is completely Inert to chemical reaction and radiation. Its thermal conductivity surpasses that of any other inert gas and is three times greater that neon, its nearest Inert competitor.
Description: Oxygen, the colorless, odorless, tasteless elemental gas that supports life and combustion, constitutes about a fifth of the atmosphere (20.95% by volume and 23.2% by weight). At temperature below -300oF (184oC), it is a transparent, pale blue liquid that is slightly heavier than water, All elements except the inert gas combine directly with oxygen to form oxides.
Description: Nitrous at room temperature and atmospheric pressure is a colorless gas with a barely perceptible sweet odor and taste. It is non-flammable but will support combustion. At elevated temperatures, nitrous oxide decomposes into nitrogen and oxygen. Decomposition in the absence of catalysts is negligible at temperatures below 100oF. Nitrous oxide is moderately soluble in water, alcohol, and oils.
Description: Oxygen, the colorless, odorless, tasteless elemental gas that supports life and combustion, constitutes about a fifth of the atmosphere (20.95% by volume and 23.2% by weight). At temperature below -300oF (184oC), it is a transparent, pale blue liquid that is slightly heavier than water, All elements except the inert gas combine directly with oxygen to form oxides. Oxygen is nonflammable but it readily supports combustions.
Description: Nitrogen makes up the major portion of the atmosphere (78.08% by volume, 75.5% by weight). It is a colorless, odorless, tasteless, nontoxic, almost totally inert gas, and is colorless as a liquid. Nitrogen is nonflammable, will not support combustion, and is not life supporting.
