  1. Chloroprene Richard Roček Jiří Švec

  2. Chloroprene – General information • Formulas: • Summar:C4H5Cl • Functional: CH2=CCl-CH=CH2 • Structural: • Names • 2-Chloro-1,3-butadiene • Chloroprene • Neoprene • Iternational notation: • CAS Registry Number: 126-99-8 • EC Registry Number: 204-818-0

  3. Chemical properities • Properities • Molecular Formula of monomer = C4H5Cl • Formula Weight = 88.5355 • Composition = C (54.26%) H (5.69%) Cl(40.04%) • Molar Volume = 95.9 ± 3.0 cm3 • Industrial production • Polymerization

  4. Physical properities • Properities of pure compound • Density 0.9598 g/cm3, • Solubility in water: insoluble. 0.2115 g/100 mL • Melting point: -130°C -202 F • Boiling point: 59.4°C 138 F 332.6 K • Colourless liquid with ether-like smell • Properities of polymer • Good mechanical and chemical endurance • High endurance against ozon and water • Low flammability • Adhesive with many materials Endurance - odolnost

  5. Spectral analysis

  6. Toxicological characteristics • Exposure limits • OSHA GENERAL INDUSTRY PEL: 25 ppm, 90 mg/m3(Skin) • OSHA CONSTRUCTION INDUSTRY PEL: 25 ppm, 90 mg/m3 TWA (Skin) • ACGIH TLV: 10 ppm, 36 mg/m3 TWA (Skin) • NIOSH REL: 1 ppm Ceiling, Potential Carcinogen • Health factors • IARC: Group 3, not classifiable as to its carcinogenicity to humans • SYMPTOM(s): Eye, respiratory system irritation; nervousness,irritability;dermatitis, alopecia; [carcinogenic] • HEALTH EFFECTS:Reproductive Hazard (HE5); SystemicToxicity (HE3),Mutagen (HE2) • ORGAN: system, skin, eyes

  7. Use of Chloroprene The best known are propably wetsuits for diving or water sports generaly, which are made of neoprene (polymerized chloroprene). wetsuit- neoprén, oblek na vodní sporty

  8. Use of neoprene Becouse of its high mechanical and chemical endurance lot of common things are made of neoprene. Such as gaskets, corrosion-resistant coatings, electrical insulation, hoses and very important are also various medical utilities Gasket –těsnění; coatings – nátěry, povrchy; electrical insulation – izolace elektrických vodičů; hose - hadice

  9. Use of chloroprene But chloroprene is also used as a component of various types of rubbers and modern materials. From mousepads to hi-tech surfaces of military stealth airplanes, witch „hides“ planes by reflecting radar waves Surface – povrch;Stealth – tajný,skrytý

  10. Thanks for your attention
