chloroacetophenone[¦klȯr·ō‚as·ə′tä·fə‚nōn] (organic chemistry) C6H5COCH2Cl Rhombic crystals melting at 59°C; an intermediate in organic synthesis. Chloroacetophenone C6H5C(O)CH2Cl, a compound obtained as colorless crystals, with a melting point of 59°C and a boiling point of 244°–245°C. Its volatility (maximum concentration) is 0.11 mg/liter at 20°C. A strong lacrimator, chloroacetophenone is poorly soluble in water but readily soluble in organic solvents. It is stable to hydrolysis; under cold conditions it practically does not hydrolyze, even in alkaline aqueous solutions. It reacts vigorously with alcohol solutions of Na2S, with the formation of nontoxic diphenacyl sulfide, (C6H5COCH2)2S. Chloroacetophenone is produced by the chlorination of acetophenone. The minimal active concentration is 0.0001 mg/liter, and the intolerable concentration, 0.002 mg/liter (for 2 min). Gas masks provide protection against the effects of chloroacetophenone. Proposed as a poison at the end of World War I, chloroacetophenone has never been tested in combat. chloroacetophenoneenUK
gas [gas] any elastic aeriform fluid in which the molecules are widely separated from each other and so have free paths.alveolar gas the gas in the alveoli of the lungs, where exchange" >gas exchange with the capillary blood takes place.blood g's the partial pressures of oxygen and carbon dioxide in blood; see blood gas analysis.laughing gas nitrous oxide.gas pains pains caused by distention of the stomach or intestines by accumulation of air or other gases. The presence of gas is indicated by distention of the abdomen, belching, or discharge of gas through the rectum. Gas-forming foods include highly flavored vegetables such as onions, cabbage, and turnips; members of the bean family; and fruits such as melons and raw apples. Some seasonings and other chemical irritants also produce gas.tear gas any of various irritant vapors dispensed by aerosol and causing pain and severe lacrimation in humans; some also cause irritation of exposed mucous membranes as well as vomiting. Common ones include chloroacetophenone (CN), o-chlorobenzylidenemalononitrile (see CS), and dibenz(b,f)-1,4-oxazepine (see cr); the most common of the three is CS (also known as mace).chlor·o·ac·e·to·phe·none (klōr'ō-ă-sē'tō-fē'nōn) A compound (NATO code CN) used as a lacrimator and riot-control agent in law enforcement, and in sprays for personal protection.
