개요
Dibutyl phthalate is included as an insect repellent in some aerosol sprays used to treat flystrike in sheep. It is colorless oily liquid with a very weak aromatic odor.화학적 성질
Dibutyl phthalate occurs as an odorless, oily, colorless, or very slightly yellow-colored, viscous liquid.물리적 성질
Colorless to pale yellow, oily, viscous liquid with a mild, aromatic odor용도
Dibutyl phthalate is used in plasticizers, cosmetics, safety glass, insecticides, printing inks, paper coatings, adhesives, elastomers and explosives; solvent in polysulfide dental impression materials; solvent for perfume oils; perfume fixative; textile lubricating agent; solid rocket propellent; emollient in aerosol antiperspirants; insect repeller; plasticizer in various plastic materials.생산 방법
Dibutyl phthalate is produced from n-butanol and phthalic anhydride in an ester formation reaction.정의
ChEBI: Dibutyl phthalate is a phthalate ester that is the diester obtained by the formal condensation of the carboxy groups of phthalic acid with two molecules of butan-1-ol. Although used extensively as a plasticiser, it is a ubiquitous environmental contaminant that poses a risk to humans. It has a role as an environmental contaminant, a teratogenic agent, a plasticiser, a metabolite and an EC 3.2.1.20 (alpha-glucosidase) inhibitor. It is a phthalate ester and a diester. It is functionally related to a butan-1-ol.일반 설명
Dibutyl phthalate is a colorless oily liquid. Dibutyl phthalate is insoluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since Dibutyl phthalate is a liquid Dibutyl phthalate can easily penetrate the soil and contaminate groundwater and nearby streams. Dibutyl phthalate is combustible though Dibutyl phthalate may take some effort to ignite. Dibutyl phthalate is used in paints and plastics and as a reaction media for chemical reactions.공기와 물의 반응
Insoluble in water.반응 프로필
Dibutyl phthalate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Avoid contact with strong oxidizing agents and strong bases. Will not polymerize. [USCG, 1999]. Can generate electrostatic charges. [Handling Chemicals Safely 1980. p. 250].건강위험
The toxicity of this compound is very low. Inhumans, oral intake of dibutyl phthalate at adose level of 150 mg/kg may cause nausea,vomiting, dizziness, hallucination, distortedvision, lacrimation, and conjunctivitis withprompt recovery. It metabolizes to monobutylester and phthalic acid and is excreted in urine.The inhalation toxicity should be insignificantbecause of its negligible low vapor pressure[<0.1 torr at 20°C (68°F)]. However, expo sure to its mist or aerosol can cause irritationof eyes and mucous membranesLD50 value, oral (mice): 5300 mg/kg.

Combustible.Pharmaceutical Applications
Dibutyl phthalate is used in pharmaceutical formulations as a plasticizer in film-coatings. It has been evaluated as a pore-forming agent in novel delivery systems.It is also used extensively as a solvent, particularly in cosmetic formulations such as antiperspirants, hair shampoos, and hair sprays. In addition to a number of industrial applications, dibutyl phthalate is used as an insect repellent, although it is not as effective as dimethyl phthalate.색상 색인 번호
It is mainly used as a nonreactive epoxy diluent.Safety Profile
Moderately toxic by intraperitoneal and intravenous routes. Mildly toxic by ingestion. Human systemic eye effects by ingestion, hallucinations, dstorted perceptions, nausea or vomiting, and kidney, ureter, or bladder changes. Experimental teratogenic and reproductive effects. Mutation data reported. Combustible when exposed to heat or flame; can react with oxidizing materials. Violent reaction with Cl2. Incompatible with chlorine. To fight fire, use CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes. See also ESTERS, PHTHALIC ACID, and n BUTYL ALCOHOL.Safety
Dibutyl phthalate is generally regarded as a relatively nontoxic material, although it has occasionally been reported to cause hypersensitivity reactions. It is widely used in topical cosmetic and some oral pharmaceutical formulations.LD50 (mouse, IV): 0.72g/kg
LD50 (mouse, oral): 5.3g/kg
LD50 (rat, oral): 8.0g/kg
LD50 (rat, IP): 3.05mL/kg
저장
Dibutyl phthalate should be stored in a well-closed container in a cool, dry, location. Containers may be hazardous when empty since they can contain product residues such as vapors and liquids.Purification Methods
Wash DBP with H2O (to free it from alcohol), then dilute NaOH (to remove any butyl hydrogen phthalate or acid), aqueous NaHCO3 (charcoal), then distilled water. Dry it (CaCl2), distil it at 10torr or less, and store it in a desiccator over P2O5. [Beilstein 9 II 586, 9 III 4102, 9 IV 3175.]비 호환성
Dibutyl phthalate reacts violently with chlorine. It also reacts with oxidizing agents, acids, bases, and nitrates.Regulatory Status
Included in the FDA Inactive Ingredients Database (oral capsules, delayed action, enteric coated, and controlled release tablets). Included in nonparenteral medicines licensed in the UK (oral capsules, tablets, granules; topical creams and solutions).다이부틸푸탈레이트 준비 용품 및 원자재
