Tributyl phosphate is a colorless liquid with a pungent odor. Vapor pressure: (180-183) ℃ (2.87 kPa) Flash point: 27.79 mN/m (20 ℃) Insoluble in water, miscible with a variety of organic solvents. Main uses: Used as a solvent, also often used as a plasticizer for nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride, an extractant for rare metals, etc., and a heat exchange medium. Due to its low surface tension and physical properties of being insoluble in water, it can be used as an industrial defoaming agent to effectively destabilize the formed foam film and quickly defoam it. Not for food/cosmetic use.
Product Usage
Use 1: Used as gas chromatography stationary liquid, solvent for nitrocellulose and ethylcellulose, plasticizer, rare earth metal separation agent and organic synthesis intermediate;
Use 2: It has good polymerization inhibition effect on acrylates, methacrylates, acrylic acid, acrylonitrile, styrene, and butadiene, and its polymerization inhibition performance is better than that of phenols;
Use three: used as an extraction agent for metal complexes, a plasticizer for nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride, and a solvent for coatings, inks and adhesives;
Use 4: Extract cobalt, iridium, manganese, molybdenum, palladium, rhodium, nickel, uranium and tungsten with gas chromatography stationary solution (maximum operating temperature 120°C, solvent is diethyl ether), and colorimetrically determine molybdenum.
The influence of phosphoric acid vapor phase silica tributyl ester
Environmental effects: Inhalation, ingestion. Health hazards: This product has a mild inhibitory effect on human blood plastic deodorant and cholinesterase in plasma. It can cause symptoms such as difficulty breathing, convulsions, paralysis, and lethargy. Irritating to skin. Vapors and fumes are irritating to eyes, mucous membranes and upper respiratory tract. Exposure may cause central nervous system irritation symptoms.
Is tributyl phosphate toxic?
Toxicological information and environmental behavior Toxicity: It has a strong irritating effect on the skin and respiratory tract, and has systemic toxic effects.
Acute toxicity: LD50 3000mg/kg (orally in rats); LC501.3g/m3, 6 hours, (three experimental rats were inhaled) without death; about 100ml in humans can cause dyspnea, convulsions, paralysis, Symptoms such as lethargy.
Subacute and chronic toxicity: guinea pigs transdermal 1ml/kg/day × 4 days, 2/3 died.
Hazardous characteristics: There is a danger of burning when exposed to high heat, open flame or contact with oxidants. It decomposes when heated to produce highly toxic phosphorus oxide fumes.
Combustion (decomposition) products: carbon monoxide, carbon dioxide, phosphorus oxide.
