N,N-Dimethylaniline 99%

Dimethyl aniline is a colorless to pale yellow oily liquid, stimulating smell, easy oxidation of sunshine in the air or make the color darker.

Dangerous features: open flame, high fever or contact with antioxidant, has caused the risk of burning explosion. Thermal decomposition released toxic of nitrous oxide gas.

Main use: used as a dye intermediates, for making vanillin, azo dye, triphenyl methane dye, and as a solvent and stabilizer, analytical reagent, etc.

Toxicity: high toxic. Inhale the steam or absorbed through the skin to cause poisoning. The toxicity and aniline are roughly the same. Is the blood poison, nerve toxicity and carcinogenicity. 5 x 10-6 maximum allowable concentration in the air. Avoid contact with skin. The site should have good ventilation operation and equipment should be closed. Operating personnel should wear protective gear.

Emergency disposal

Skin contact: remove contaminated clothing and immediately with soap and water and water to thoroughly flushed the skin. Go to a doctor.

Eye contact: mention eyelid, irrigate with flowing water or normal saline. Go to a doctor.

Inhalation: quickly from the scene to fresh air. Keep respiratory tract unobstructed. Such as difficulty in breathing, give oxygen. If breathing stops, artificial respiration immediately. Go to a doctor.

Eating: drink enough water, vomiting. Go to a doctor.

Respiratory protection: may contact the steam, wearing a filter type gas mask (half mask). Emergency rescue or evacuation, wearing the respirator in isolation.

Eye protection: wear chemical safety goggles.

Body protection: wear protective material penetration overalls.

Hand protection: wear oil resistant rubber gloves.

Other protection: work site no smoking, eating and drinking water. Change clothes in time. Don't drink before and after work, to take a bath with warm water. Pay attention to detect poisons. Before the employment and the regular physical examination.

Leakage emergency handling: leave quickly leak contaminated area personnel to safe areas, and in isolation, restricted access. Cut off the fire. Recommended emergency personnel wearing self positive pressure respirator, wear protective clothing. Don't direct contact with the leakage. Cut off the leak source as possible. Prevent into the sewer, ditch having restricted space. A small leak: with sand or other incombustible material adsorption or absorption. A large number of leak: constructing dike to dig a hole or asylum. In foam cover, reduce the steam disasters. Pump to tank lorry or dedicated collector, recycling or shipped to the disposal of waste places.

Combustion hazard: this product is flammable, toxic.

Hazardous combustion products: carbon monoxide, carbon dioxide and nitrogen oxides.

Extinguishing method: using water fog, foam, carbon dioxide, dry powder, sand put out the fire.

Management information

Operation management: airtight operation, to provide adequate local exhaust. Operators must receive special training, strictly abide by the operation procedures. Suggest operators wear filter type gas mask (half mask), wearing chemical safety protective glasses, wear gas permeability overalls, wear oil resistant rubber gloves. Away from fire and heat source, the workplace smoking is strictly prohibited. Use explosion-proof ventilation systems and equipment. To prevent the steam leakage in the air of workplace. Avoid contact with acids, halogen. Light light discharge when handling to prevent damage to packaging and container. Equipped with corresponding varieties and number of fire equipment and spill contingency processing equipment. Empty containers may remain inside.

Storage management: store in a cool, ventilated warehouse. Away from fire and heat source. Keep container sealed. Should with acids, halogen, edible chemicals stored separately, mixed reservoir of avoid by all means. Equipped with corresponding varieties and number of fire equipment. Storage area should be equipped with emergency treatment equipment and suitable for material.

Should be taken before transportation management: check whether the container is full, sealing, to ensure that the container does not leak during the process of transportation, do not fall, do not fall, no damage. It is strictly prohibited and acids, antioxidants, during food and food additives. Transport transport vehicles should be equipped with corresponding varieties and number of fire equipment and spill contingency processing equipment. Transit should prevent insolate, rain, heat. Highway transportation route as prescribed.

Disposal of waste management: by burning method. Nitrogen oxides incinerator discharge through the scrubber to remove.
