Overview
Tributyl phosphate is used as a solvent. It is also often used as a plasticizer for nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride, an extractant for rare metals, etc., and is also used for heat exchange. medium.
Purpose
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 pigment carbon melanin, cellulose acetate, chlorinated rubber and polyvinyl chloride, and a solvent for coatings, inks and adhesives
p>
Use 4: Used as the main plasticizer of cellulose nitrate, cellulose acetate, chlorinated rubber and polyvinyl chloride. It is also commonly used as a solvent, defoaming agent and antistatic agent for coatings, adhesives and inks. Extractant for rare earth elements. Rat LD50 is 3000mg/kg.
Use 5: Nitrocellulose and cellulose acetate solvents, defoaming agents, heat exchange media, plasticizers, and extraction agents. Gas chromatography stationary solution (maximum operating temperature 120°C, solvent is diethyl ether) extracts cobalt, iridium, manganese, molybdenum, palladium, rhodium, nickel, uranium and tungsten, and colorimetrically determines molybdenum. Organic Synthesis.
Health Hazards
Routes of invasion: inhalation, ingestion.
Health hazards: This product has a mild inhibitory effect on cholinesterase in human blood and plasma. When taken orally, about 100 ml 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.
Leakage
Evacuate personnel in the leaked contaminated area to a safe area, prohibit irrelevant personnel from entering the contaminated area, and cut off the source of fire. Emergency responders wear gas masks and protective clothing. Plug the leak while ensuring safety. Rinse with plenty of water and put the diluted washing liquid into the wastewater system. If there is a large amount of leakage, use dikes to contain it. Then collect, transfer, recycle or dispose of them after harmless treatment.
Protective measures
Respiratory system protection: When the concentration in the air exceeds the standard, wear a mask-type respirator. During emergency rescue or evacuation, wear self-contained breathing apparatus Hanwha Acrylic Resin.
Eye protection: Wear chemical safety glasses.
Protective clothing: Wear overalls.
Hand protection: Wear rubber gloves.
Others: Smoking, eating and drinking are prohibited at the work site. After work, shower and change clothes. Maintain good hygiene habits.
First aid measures
Skin contact: Take off contaminated clothing and wash thoroughly with soap and water.
Eye contact: Open the upper and lower eyelids immediately and rinse with running water for 15 minutes. Seek medical attention.
Inhalation: Leave the scene to fresh air. Give oxygen if breathing is difficult. Once breathing stops, begin CPR immediately.
Ingestion: If swallowed by mistake, rinse mouth immediately, drink milk or egg white, induce vomiting, and perform gastric lavage. Seek medical attention.
Fire-fighting methods: foam, carbon dioxide, dry powder, sand.
