2-Butanone
Messageoverview
2-Butanone colorless clear liquid. Have an acetone-like odor.volatile. It can be miscible with ethanol, acetic ether, benzene, chloroform and oil. Disdissolved in 4 parts of water, but the solubility decreased when the temperature increased. It can form a boiling mixture with water (11.3% water) with a boiling point of 73.4℃ (88.7% butanone). Relative density (d204) 0.805. Cooling point-86℃. Boiling point of 79.6℃. Rerate (n15D) 1.3814. Flash point of 1.1℃. Low toxicity, half lethal (rat, oral) 3300 mG / kG. Flammable, vapor can form an explosive mixture with air, with the explosive limit of 1.81%~11.5% (volume). High concentration of steam is anesthetic.
use
1、Used as solvent for cellulose acetate, acrylic resin, alkyd resin, paint, ink, etc., binder for dyestuff, dewaxing agent for lubricating oil, vulcanization accelerator, etc.
2、Used as a reagent for the determination of cadmium, copper and mercury, as a standard for chromatographic analysis and as a solvent for semiconductor lithography
3、GB 2760-96 stipulates that it is allowed to be used as edible spices. Mainly used in the preparation of cheese, coffee and banana-type flavours. It can also be used as an extraction solvent.
4, mainly used as a solvent, such as for lubricating oil dewaxing, coating industry and a variety of resin solvents, vegetable oil extraction process and refining process of azeotropic distillation, its advantage is strong solubility, lower volatility than acetone, is a medium boiling point ketone solvent. Butanone is also the preparation of pharmaceuticals, dyes, detergents, spices, antioxidants and certain catalysts is an intermediate, the synthesis of anti-peeling agent methyl ethyl ketoxime, polymerization catalyst methyl ethyl ketone peroxide, corrosion inhibitor methyl pentethynyl alcohol, etc., in the electronics industry used as a developer after the lithography of integrated circuits.
5. It is the raw material for the preparation of the acaricide pyriproxyfen.
Health hazards
Route of entry: inhalation, ingestion, transdermal absorption.
Health hazard: Irritating to eyes, nose, throat and mucous membranes. Prolonged exposure can cause dermatitis. This product is often mixed with 2-hexanone to enhance the peripheral neuropathy caused by 2-hexanone, but no peripheral neuropathy has been observed with butanone exposure alone.
Flammability hazard: The product is flammable and irritating.
Toxicological information and environmental behaviour
Toxicity: It is in the low toxicity category.
Irritation: Trans-ocular in rabbits: 80mg, causing irritation. Open percutaneous irritation test in rabbits: 13780µg (24 hours), mildly irritating.
Mutagenicity: Sex chromosome deletion and non-disjunction: Brewer's yeast 33,800ppm.
Reproductive toxicity: Minimum toxic concentration by inhalation (TCLo) in rats: 3000ppm (7 hours), (6-15 days gestation), causes abnormal craniofacial (including nose and tongue) development, causes abnormal development of the genitourinary system, causes abnormal blood clotting.
Hazardous characteristics: Flammable, its vapour and air can form an explosive mixture. When exposed to open flame, high heat or contact with oxidizing agents, there is a risk of combustion and explosion. The vapour is heavier than air and can diffuse to a considerable distance at a lower level and can ignite in the presence of an open flame.
Protective measures
Respiratory protection: A self-absorbing filtering gas mask (half mask) should be worn if the airborne concentration exceeds the limit.
Eye protection: If necessary, wear chemical safety glasses.
Body protection: Wear anti-static overalls.
Hand protection: Wear latex gloves.
Other: Smoking is strictly prohibited on the work site. Pay attention to personal cleanliness and hygiene. Avoid prolonged and repeated contact.
First aid measures
Skin contact: Remove contaminated clothing and rinse skin thoroughly with soapy water and water.
Eye contact: Lift eyelids and flush with running water or saline. Seek medical attention.
INHALATION: Remove quickly from the scene to fresh air. Keep airway open. If breathing is difficult, give oxygen. If breathing stops, give immediate artificial respiration. Seek medical attention.
Ingestion: Drink sufficient warm water, induce vomiting and wash stomach with water or 1% sodium thiosulphate solution. Seek medical attention.
Storage method
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The temperature should not exceed 30°C. Keep containers sealed. Store separately from oxidising agents, reducing agents and alkalis, do not mix. Use explosion-proof lighting and ventilation facilities. Do not use spark-prone machinery and tools. The storage area should be equipped with spill response equipment and suitable shelter materials.
