Bisphenol A and bisphenol B are two common dihydric phenol compounds. They have slight differences in structure, but they have a wide range of applications in the fields of chemical industry, biodegradable plastics and plasticizers. This article will analyze the difference between bisphenol A and bisphenol B in detail from the aspects of structure, application, advantages and disadvantages, and provide readers with practical suggestions.

1. what is bisphenol A and bisphenol B?

Both bisphenol A and bisphenol B are derivatives of dihydric phenols, formed by esterification of two phenolic hydroxyl groups. The basic structure is similar, but the position and number of hydroxyl groups are slightly different.

Structure of bisphenol A Bisphenol A consists of two phenolic hydroxyl groups linked by an ester group to form a symmetrical structure. Its molecular formula is C6H4(COOH)2, in which two phenolic hydroxyl groups are located on the same side, forming a six-membered ring structure.
Structure of bisphenol B The structure of bisphenol B is similar to that of bisphenol A, but the two phenolic hydroxyl groups are located on opposite sides, forming a trans structure. Its molecular formula is also C6H4(COOH)2, but structural differences lead to its physical
