Brief introduction
Bisphenol A (BPA) is an organic compound. Bisphenol A is a colorless to yellowish solid that is soluble in organic solvents such as ketones and esters.
A common method for the preparation of bisphenol A is through the condensation reaction of phenols and aldehydes, generally using acidic catalysts. During the preparation process, the reaction conditions and the choice of catalyst need to be controlled to obtain high-purity bisphenol A products.
Safety Information: Bisphenol A is considered to be toxic and potentially harmful to the environment. Studies have shown that BPA may have a disrupting effect on the endocrine system and is thought to have adverse effects on the reproductive, nervous and immune systems. Long-term exposure to BPA can have a negative impact on the development of infants and children.
