17637-11-5 - Introduction
tartaric anhydride dibenzoate is an organic compound also known as O,O'-biphenyl-L-tartaric dianhydride. Its molecular formula is C14H10O6, corresponding to a molecular weight of 298.22g/mol. It is a colorless or yellowish crystalline solid with a bitter taste.
tartaric anhydride dibenzoate has a wide range of applications. It can be used as a chiral reagent for asymmetric reactions in Chiral synthesis. It can also be used as an asymmetric catalyst and resolving agent in catalysis and separation processes. In addition, tartaric anhydride dibenzoate can also be used to prepare chiral dyes, drugs, etc.
The preparation of tartaric anhydride dibenzoate is usually obtained by reducing deoxy benzoate. First, deoxybenzoate is dissolved in an appropriate amount of ethanol, and an appropriate amount of sodium alkoxide is added to suspend it. Then, a reduction reaction is carried out at an appropriate temperature and pressure. After the reaction is completed, cooling is carried out and an acid is added to precipitate the tartaric anhydride dibenzoate. Finally, the pure product is obtained by filtering, washing and drying.
About the safety information of tartaric anhydride dibenzoate, it may have irritating effect on eyes, skin and respiratory tract. Therefore, care should be taken to wear appropriate protective equipment, such as laboratory gloves, goggles and dust masks. In case of exposure to the compound, rinse the affected area immediately with plenty of water and seek medical attention immediately. In addition, tartaric anhydride dibenzoate should be stored in a dry, dark and sealed container, away from fire and oxidizing agents.
