Read： 832 Time：13months ago Source：Transform the World with Simplicity

Dibenedione is an important organic compound, and its preparation process requires attention to some key issues to ensure the smooth progress of the preparation process and obtain high-purity products.

raw materials and solvents for the preparation of diphenedione need to be kept dry and high purity, especially for commonly used reagents and solvents such as benzoyl hydroperoxide (HPMPA) and dichloromethane, the moisture and impurity content must be strictly controlled.
the selection of
reaction conditions is also critical, the keto-alcohol condensation reaction is usually used to prepare dibenedione, and the reaction temperature and time need to be controlled to prevent side reactions or incomplete reaction products. In addition, the separation and purification of the product also need to be carefully operated, and the product can be purified by crystallization, distillation and other methods to obtain high-purity dibenedione.

preparation of dibendione needs to pay attention to the purity of raw materials, reaction conditions and product purification and other key issues, only strictly abide by these precautions, in order to obtain high-quality products.
