Bisphenol A (4,4’-isopropylidenediphenol, BPA)는 아세톤과 2분자의 페놀 축합에 의해 합성되는 단량체(monomer)이다. 식품의 포장용기로 사용되고 있는 epoxy resin 이나 polycarbonate(PC) plastic의 원료 물질로써, 비스페놀A는 캔의 부식을 방지하거나, 열에 대한 저항성과 내구성을 높이기 위하여 플라스틱 병의 첨가물로 사용되고 있다.용도
비스페놀 A(BPA: Bisphenol A)는 지구상에서 가장 흔히 쓰이는 화합물의 하나이며, 폴리카보네이트와 에폭시 수지 등의 생산에 쓰인다.개요
Reports of bisphenol- A sensitization, particularly in workers at epoxy resin plants, are controversial. Bisphenol-A was also reported as an allergen in fiberglass, semisynthetic waxes, footwear and dental materials.화학적 성질
Bisphenol A is a white or tan crystals or flakes with a mild phenolic odor and a very low vapor pressure (ECB, 2003). It is mildly soluble in water. It is not considered to be an explosive in the conventional sense but can pose a hazard as a finely powdered material in air (ECB, 2003). It is not considered to be a chemical oxidizer.역사
Bisphenol A (BPA) was first synthesized in 1891, but it was not used widely until applications in the plastics industry were identified in the 1950s (University of Minnesota, 2008). While the most prominent use of BPA is in the manufacture of polycarbonate plastic and epoxy resins, it is also used in the production and processing of polyvinyl chloride (PVC) and modified polyamide and in the manufacture of carbonless and thermal paper, wood filler, adhesives, printing inks, surface coatings, polyurethane, brake fluid, resin-based dental composites and sealants, flame retardants, paints, and tires (ECB, 2003; EFSA, 2006).![Bisphenol A](https://www.chemicalbook.com/NewsImg/2020-02-07/20202720391750896.jpg)
용도
Bisphenol A (BPA) is used as the constitutional monomer or the monomeric building block of polycarbonate plastics, either by trans-esterification with diphenyl carbonate or via the interfacial process with a monohydroxylic phenol. Together with epichlorohydrin, BPA is also used as a major component of epoxy resins. Bisphenol A-polycarbonate plastics are in turn used in the manufacture of plastic food containers such as reusable water bottles, while epoxy resins are used as inner linings of tin cans. In addition, BPA is also used as an additive in other plastics and polymers, particularly as an antioxidant or stabilizer in polyvinyl chloride, printer ink, and in some other products.정의
ChEBI: A bisphenol that is 4,4'-methanediyldiphenol in which the methylene hydrogens are replaced by two methyl groups.제조 방법
The formation of bisphenol A is thought to proceed as follows:Although the reaction theoretically requires the molar ratio of reactants to be 2: 1, an improved yield of bisphenol A is obtained if additional phenol is present; the optimum molar ratio is 4: 1. In a typical process, the phenol and acetone are mixed and warmed to 50??C. Hydrogen chloride (catalyst) is passed into the mixture for about 8 hours, during which period the temperature is kept below 70??C to suppress the formation of isomeric products. Bisphenol A precipitates and is filtered off and washed with toluene to remove unreacted phenol (which is recovered). The product is then recrystallized from aqueous ethanol. Since epoxy resins are oflow molecular weight and because colour is not normally particularly important, the purity of bisphenol A used in resin production is not critical. Material with a p,p'-isomer content of 95-98% is usually satisfactory; the principal impurities in such material are o,p'- and o,o'-isomers.

Bisphenol A is used with epichlorhydrin for the synthesis of epoxy resins bisphenol-A type, for unsaturated polyester and polycarbonate resins, and epoxy di(meth)acrylates. In epoxy resins, it leads to bisphenol-A diglycidyl ether, which is the monomer of bisphenol-A-based epoxy resins. Reports of bisphenol-A sensitization are rare and concern workers at epoxy resin plants, after contact with fiber glass, semi-synthetic waxes, footwear, and dental materials. It is also a possible sensitizer in vinyl gloves.잠재적 노출
Workers engaged in the manufacture of epoxy, polysulfone, polycarbonate and certain polyester resins. It is also used in flame retardants, rubber chemicals, and as a fungicide. Bisphenol A (BP A), an environmental estrogen, is found in a wide variety of products, including polycarbonate bottles food and drink containers. According to 2008 research conducted at University of Cincinnati, when it comes to BPA, it’s not whether polycarbonate bottles are new or old but the liquid’s temperature that has the greatest impact on how much BPA is released. When exposed to boiling hot water, BPA was released 55 times more rapidly than exposure to cold water.환경귀착
Bisphenol A can be released into the environment during the production, processing, and use of BPA-containing materials, although levels in environmental samples are generally very low or undetectable (ECB, 2003). This is because BPA has low volatility and a short half-life in the atmosphere, is rapidly biodegraded in water, and is not expected to be stable, mobile, or bioavailable from soils (ECB, 2003; Cousins et al., 2002).Most environmental releases of BPA are during the manufacture of BPA-containing products when residual BPA in wastewater is released from treatment plants into receiving streams (Cousins et al., 2002). BPA's half-life in soil and water is in the order of 4.5 days while in air it is <1 day (Cousins et al., 2002). It has a low bioconcentration factor and is rapidly metabolized in fish, with a half-life of <1 day (Cousins et al., 2002).

UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9—Miscellaneous hazardous material, Technical Name Required.Purification Methods
Crystallise bisphenol from acetic acid/water (1:1). It is used for making polycarbonate bottles and leaches out slowly on heating. It is a known “estrogenic chemical” shown to disrupt chemical signaling in the complex network of glands, hormones and cell receptors which make up the endocrine system. It causes low sperm count and damages the ecosystem by the feminisation of fish, reptiles and birds. [cf Chapter 1, p 3, Beilstein 6 IV 6717.]비 호환성
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, acid chlorides and acid anhydrides.비스페놀-A 준비 용품 및 원자재
