4-tert-butylphthalic anhydride - Introduction
4-tert-butylphthalic anhydride is an organic compound with the chemical formula C14H18O3. The following is a description of its nature, use, preparation and safety information:
Nature:
4-tert-butylphthalic anhydride is a white crystal or crystalline powder. It is insoluble in water at room temperature, but soluble in organic solvents such as ethers, ketones and alcohols. It has a higher melting point and boiling point, and good thermal stability.
Use:
4-tert-butylphthalic anhydride is mainly used for chemical reactions in organic synthesis. It can be used as an acid catalyst to participate in esterification, transesterification and cyclization reactions. In addition, it can also be used as a synthetic intermediate of organic materials for the preparation of dyes, polymer materials and coatings and other chemicals.
Method:
4-tert-butylphthalic anhydride can be prepared by reacting phthalic acid with tert-butyl alcohol to generate the corresponding esterification product. The alcohol group in the product is then converted to an anhydride group by a dehydration reaction to give the 4-tert-butylphthalic anhydride product.
Safety Information:
When dealing with 4-tert-butylphthalic anhydride, you need to pay attention to avoid contact with the skin to avoid irritation. At the same time, it is necessary to use appropriate personal protective equipment, such as chemical gloves and protective glasses, to prevent inhalation or swallowing. This compound should be stored in a dry, well-ventilated place, away from high temperatures and sources of ignition.
