Molecular Formula C2H2ClN; ClCH2< / SUB>CN
colorless liquid, irritating odor; vapor pressure 1.06kPa/20 ° C a flash point of 47 ° C; the boiling point of 126 ° C (Decomposition ); solubility : not soluble in water, soluble in hydrocarbons, alcohols; density : relative density (water = 1) 1.19; the relative density (Air = 1) 3.0; Stability : stability; risk Marker 14 (drugs); the main purpose use for pesticides, organic synthesis intermediate
2. The impact on the environment
the material harm to the environment, with special attention to water pollution.
a health hazard
pathways : inhaled, ingested, percutaneous absorption.
health hazard : if inhaled, swallowed or absorbed through the skin and may cause death. Ophthalmic vapor or mist, the mucosa and respiratory irritant on. Can cause cyanosis.
two, toxicology information and environmental behavior
toxicity : it is a high drug category.
acute toxicity : LD50220mg/kg (rat oral); 71mg/kg (rabbit percutaneous)
subacute and chronic toxicity : rats inhaled 903mg/m3 × 5 hours / × 3 times, difficult breathing, and the District of Tianjin, the Movement disorders, the temperature dropped, congestive offal.
hazardous characteristics : case of fire, heat flammable. Heating minutes to explain high-vapor poisoning. With water or water vapor, acid or sour gas produced toxic flammable gas. Contact with strong oxidant chemical reaction can occur.
combustion (decomposition) products : carbon monoxide, carbon dioxide, nitrogen oxides, hydrogen chloride.

5. Environmental standards
6. Emergency treatment and disposal methods
a leakage contingency
rapid withdrawal from air leakage personnel to a safe area, and immediately quarantine 150m, and strictly limit access. Cut off the fire source. Recommended emergency personnel wearing self-Pressurized respirators to wear protective clothing. Upwind from entering the scene. As far as possible, cut off the source of leakage, prevent access to sewers, flood discharge trench so restrictive space. A small leak : sand or other materials Unburning adsorption or absorption. We could also use non-flammable dispersant made of latex, wash, lotion diluted Add to the wastewater system. Large leak : to build a causeway or trenching asylum. Foam coverage, lower vapor disasters. Ex pump used to transfer tankers or exclusive collector, recycling or shipped to the disposal of waste disposal sites.
two protective measures
respiratory protection : its vapor may come into contact with, they should wear self-absorption filter respirators (full cover). Emergency rescue or evacuation, it is recommended to wear respirators isolated.
eye protection : Respiratory Protection has been protective.
physical protection : Polyethylene wear protective clothing.
hand protection : Wear rubber gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, thorough cleansing. Overalls are not allowed to bring non-work areas. Separate storage of toxic pollution by the clothes, washed standby.
three, and emergency measures
contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed skin. Medical treatment.
eye contact : Did eyelid, mobile or saline irrigation water. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. If breathing is difficult, give oxygen. Respiratory heartbeat stop immediately mouth (not to use oral counterparts) and thoracic cardiac massage for. To inhalation isoamyl nitrite. Medical treatment. Fresh into
: warm water to drink enough, the symptoms, using 1:5000 potassium permanganate or 5% sodium thiosulfate solution gastric lavage. Medical treatment.
fire fighting methods : firefighters are required to wear gas masks, body wear firefighting suits. Extinguishant : dry powder, carbon dioxide and sand. Ban water, and acid-base foam fire extinguishing agent.
