디사이클로펜타디엔 C화학적 특성, 용도, 생산
용도
생산 자료로 사용 되며 살충제, 향신료, 카레와 합성 고무 등의 다른 분야와 의료 분야에 널리 사용. 게다가, dicyclopentadiene는 고 에너지 연료의 종류 이다. 그리고 또한 고성능 레이저 다이오드 및 태양 전지의 준비에 사용.기타 역할
도데 실 벤젠 술폰산 나트륨의 산물이 널리 사용됩니다. 위에서 언급 한 용도 외에도 면화 직물 정련, 염색 용 평탄 화제, 금속 도금 공정의 금속 탈지제 등의 섬유 보조제로 주로 사용됩니다 . 제지 산업에서 수지 분산제, 펠트 세제, 탈 잉크 제; 가죽 산업에서 침투 탈지제로 사용; 비료 공업에있는 반 caking 대리인으로 사용하는; 시멘트 산업에서, 이는 폭기 제 단독 또는 화합물과 같은 많은 측면에서 사용된다.개요
비자성이며 모스 굳기는 2.5이다. 습한 공기 중에는 표면만 산화되며 이로 인해 내부가 보호된다.(그래서 산화될 가능성이 높은 수도관 등을 아연으로 도금하기도 한다.) 공기 중에서 내식성은 아연의 순도가 높으면 높을수록 좋다고 한다. 공기 중에서 가열하면 흰색의 불꽃을 내며 탄 후, 녹색의 산화물이 된다. 적열 상태에서는 물을 분해해 수소를 발생시키기도 한다.화학적 성질
Dicyclopentadiene (DCPC) is a dimer of cyclopentadiene. First heating is used to copolymerize cyclopentadiene into dicyclopentadiene, dicyclopentadiene is separated from other light components (boiling point <45°C) by distillation, and then other required dienes, monocyclopentadiene are separated by solvent extraction. Alkene and saturated hydrocarbon components. High-purity dicyclopentadiene is a colorless crystal at room temperature. When it contains impurities, it is a light yellow oily liquid with a pungent camphor smell. It is insoluble in water and soluble in organic solvents such as alcohol and ether.cyclopentadiene, although a stable molecule, has a strong tendency to form the more stable dimer dicyclopentadiene. This dimerisation already takes place at room temperature and its rate rapidly increases with elevated temperatures. This reaction however is reversible too; dicyclopentadiene "cracks" at temperatures above 140°C to form two cyclopentadiene molecules.
용도
Dicyclopentadiene is used in resins, particularly unsaturated polyester resins. It plays a major role in inks, adhesives and paints. It is also used as a monomer in polymerization reactions. It is a precursor for the preparation of endo-tetrahydrodicyclopentadiene, which reacts with aluminum chloride at higher temperature to give adamantine. It undergoes a retro-Diels-Alder reaction to yield cyclopentadiene, which acts as ligand in inorganic chemistry.제조 방법
Dicyclopentadiene is formed by the spontaneous dimerization of cyclopentadiene by Diels-Alder reaction insolution.생산 방법
Dicyclopentadiene is produced by recovery from hydrocarbon streams from high temperature cracked petroleum fractions. It is also a by-product of the coke oven industry. Cyclopentadiene polymerizes to dicyclopentadiene on standing.일반 설명
Dicyclopentadiene appears as a liquid with an acrid odor. Flash point 90°F. The vapors are irritating to the eyes and respiratory system. Subject to polymerization if subjected to heat for prolonged periods or if contaminated. If the polymerization takes place inside a container, the container may violently rupture. Insoluble in water. Density 8.2 lb / gal. Used in paints, varnishes, as an intermediate in insecticides, as a flame retardant in plastics.공기와 물의 반응
Highly flammable. Insoluble in water.반응 프로필
Dicyclopentadiene may react vigorously with oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. Can undergo exothermic polymierization reactions In the presence of various catalysts (such as acids) or initiators, if subjected to heat for prolonged periods, or if contaminated. Many undergo autoxidation upon exposure to the air to form explosive peroxides.건강위험
LIQUID OR SOLID: Irritating to skin and eyes.화재위험
FLAMMABLE. Flashback along vapor trail may occur. Vapor may explode if ignited in an enclosed area.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: May occur in presence of acids, but not hazardous; Inhibitor of Polymerization: Not pertinent.Safety Profile
Poison by ingestion and intraperitoneal routes. Moderately toxic by inhalation. Mildly toxic by skin contact. A severe skin and moderate eye irritant. Dangerous fire hazard when exposed to heat or flame; can react with oxidizing materials. To fight fire, use alcohol foam. When heated to decomposition it emits acrid smoke and fumes.잠재적 노출
This compound is used in the manufacture of cyclopentadiene as a pesticide intermediate; in the production of ferrocene compounds; in paints, varnishes, and resin manufacture; in production of elastomers, resin systems, and polymers.Carcinogenicity
Undiluted dicyclopentadiene caused minor irritation when applied to the skin of rabbits, and only trace injury occurred when instilled in the eye.Dicyclopentadiene has a camphorlike odor with a 100% recognition threshold of 0.02ppm; however, there may not be noticeable irritation below 10ppm.
The 2003 ACGIH threshold limit valuetime- weighted average (TLV-TWA) for dicyclopentadiene is 5ppm (27mg/m3).
운송 방법
UN2048 Dicyclopentadiene must carry a “FLAMMABLE LIQUID” label. It falls in Hazard Class 3비 호환성
Forms explosive mixture with air above flash point. Depolymerizes at boiling point and forms two molecules of cyclopentadiene; unless inhibited and maintained under inert atmosphere to prevent polymerization. Violent reaction with strong oxidizers; strong acids; strong bases. Can accumulate static electrical charges, and may cause ignition of its vapors폐기물 처리
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.디사이클로펜타디엔 준비 용품 및 원자재
