o-자일렌 C화학적 특성, 용도, 생산
화학적 성질
colourless liquid물리적 성질
Clear, colorless liquid with an aromatic odor. An odor threshold concentration of 380 ppbv was reported by Nagata and Takeuchi (1990).용도
o-Xylene is largely used in the production of phthalic anhydride, and is generally extracted by distillation from a mixed Xylene stream in a plant primarily designed for p-Xylene production.정의
ChEBI: A xylene substituted by methyl groups at positions 1 and 3.일반 설명
A colorless watery liquid with a sweet odor. Less dense than water. Insoluble in water. Irritating vapor.공기와 물의 반응
Highly flammable. Insoluble in water.반응 프로필
1,2-Dimethylbenzene may react with oxidizing materials. .건강위험
Vapors cause headache and dizziness. Liquid irritates eyes and skin. If taken into lungs, causes severe coughing, distress, and rapidly developing pulmonary edema. If ingested, causes nausea, vomiting, cramps, headache, and coma. Can be fatal. Kidney and liver damage can occur.화재위험
Behavior in Fire: Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back.화학 반응
Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.Safety Profile
Moderately toxic bj7 intraperitoneal route. Mldly toxic by ingestion and inhalation. An experimental teratogen. A common air contaminant. A very dangerous fire hazard when exposed to heat or flame. Explosive in the form of vapor when exposed to heat or flame. To fight fire, use foam, CO2, dry chemical. Incompatible with oxidzing materials. When heated to decomposition it emits acrid smoke and irritating fumes. Emitted from modern building materials (CENEAR 69,22,91). See also other xylene entries.Purification Methods
o-Xylene (4.4Kg) is sulfonated by stirring for 4hours with 2.5L of conc H2SO4 at 95o. After cooling, and separating the unsulfonated material, the product is diluted with 3L of water and neutralised with 40% NaOH. On cooling, sodium o-xylene sulfonate separates and is recrystallised from half its weight of water. [A further crop of crystals is obtained by concentrating the mother liquor to one-third of its volume.] The salt is dissolved in the minimum amount of cold water, then mixed with the same amount of cold water, and with the same volume of conc H2SO4 and heated to 110o. o-Xylene is regenerated and steam distils. The distillate is saturated with NaCl, the organic layer is separated, dried and redistilled. [Beilstein 5 H 362, 5 I 179, 5 II 281, 5 III 807, 5 IV 917.]o-자일렌 준비 용품 및 원자재
