Triisobutyl phosphate Chemical Properties,Usage,Production

Description Triisobutyl phosphate (TIBP) is a very strong polar solvent, sometimes known as Phosphoric acid triisobutyl ester. It is primarily used as an admixture for liquefying concrete, paper coating systems, and textile auxiliaries. It is mainly used as an antifoaming agent in various aqueous systems, where it can destroy foam and act as a foam inhibitor. TiBP is also used to introduce solutions for synthetic resins and natural rubber. In both ellulose-based plastics and synthetic resins, it is used as a flame-retarding plasticizer. TiBP is employed as a pasting agent for pigment pastes. Due to the limited influence of temperature on the viscosity of TiBP, it also serves as an important component in the manufacture of hydraulic fluids for aircraft. As a very strong wetting agent, TiBP is used in the textile industry and the field of adhesives.
Uses Phosphate esters are used as flame retardants, plasticizers, hydraulic fluids, solvents, extraction agents, antifoam agents,
Partition behavior in water, sediment, and soil
Phosphate ester flame retardants enter the environment from industrial sources and disposal of consumer products containing flame retardants. These anthropogenic compounds have been detected in water, soil, and air owing to widespread use following their fast emergence and popularization during 1970s. Occurrence of these phosphate ester flame retardants is widespread in surface water and groundwater because of the leaching of PVC plastics and polyurethane foams, effluent from industrial sources, and spills of hydraulic fluids. This primary contaminated water is then transported to a secondary source, such as drinking water. Hydrolysis, although slow because of poor solubility and pH dependence, is the most important abiotic elimination process. In soil and sediment, phosphate ester flame retardants are persistent because they have the tendency to adsorb strongly. Volatilization and biodegradation are potential elimination processes for phosphate esters adsorbed to soil.
Environmental persistency (degradation/speciation)
These retardants can change chemical composition in the environment. Generally, most phosphate esters are poorly soluble in water and adsorb strongly to soils. These compounds are considered emerging pollutants because of their prevalence and persistence in the environment. Particulate-phase phosphate esters are subject to wet and dry deposition, whereas semi-volatile phosphate esters have the potential to hydrolyze to diesters, monoesters, and phosphoric acid. There is no information available that suggests that selected phosphate ester flame retardants undergo transformation or degradation in the atmosphere.
Long-range transport
This is highly dependent on the specific compound.
Bioaccumulation and biomagnification
Phosphate esters are subject to biodegradation in aquatic and terrestrial environments.
Uses Phosphoric Acid Tris(2-?methylpropyl) Ester is found in the groundwater downgradient of a landfill (Grindsted, Denmark). It is also a flame retardant and plasticizer.
Definition ChEBI: Tri-isobutylphosphate is a trialkyl phosphate.
Flammability and Explosibility Not classified
Environmental Fate Routes and pathways relevant physicochemical properties (e.g., solubility, Pow, Henry constant.)consumer and industrial items and play an important role in safeguarding life and property. A large and diverse group of anthropogenic compounds constitute flame retardants, which are added to combustible materials to render them more resistant to ignition. They are designed to minimize the risk of a fire in the event of contact with a small heat source such as a cigarette. A wide range of different flame retardants is produced, because many materials and products that are to be rendered fire safe are very different in nature and composition. Therefore, having variety in flame retardant products is necessary so as to retain key material functionality. For example, plastics have a wide range of mechanical and chemical properties and differ in combustion behavior. These materials in particular are the main focus of phosphate ester flame retardants.
Phosphate esters are derivatives of tri protic acid, phosphoric acid, with a general formula of RxH3°xPO4. Flame retardants are composed of a group of chemicals with similar properties but slightly different structures. They are typically liquids and some are solids at room temperature. Some examples of the phosphate ester flame retardants include: tris(2-chloroethyl)phosphate (TCEP), tributyl phosphate (TnBP), tris(2-butoxyethyl) phosphate (TBEP), tris(1,3-dichloro-2-propyl) phosphate (TDCP), triphenyl phosphate (TPP), tris(2-chloro-isopropyl) phosphate (TCPP), and triisobutyl phosphate (TiBP). These compounds are trisubstituted and categorized as alkyl (TnBP, TiBP), alkyl ether (TBEP), chloroalkyl (TCEP, TCPP, TDCP), and aryl (TPP) phosphate esters.
Purification Methods Purify it by repeated crystallisation, from hexane, of its addition compound with uranyl nitrate. (see tributyl phosphate.) [Siddall J Am Chem Soc 81 4176 1959; see Cherbuliez in Organo Phosphorus Compounds (Kosolapoff & Maier eds) Wiley Vol 6 pp 211-577 1973.]
Toxics Screening Level The initial threshold screening level (ITSL) for triisobutyl phosphate (CAS# 126-71-6] is 22 μg/m3 based on an 8-hour averaging time. This memo describes the basis and derivation of the ITSL.
