3-oxabicyclo[3.2.1]octane-2,4-dione,1,8,8-trimethyl-,(±)- - Introduction
Camphoric anhydride is an organic compound with the chemical formula C10H14O3. It is a white crystalline solid, soluble in alcohol and ether, but insoluble in water. Camphor anhydride has a special smell and spicy taste.
Camphoric anhydride is mainly used for the preparation of other organic compounds, especially for the synthesis of various types of camphor derivatives. It is an intermediate in the process of camphor synthesis and can be used as a starting material for camphor synthesis. In addition, it can also be used as a catalyst, an oxidizing agent and a reducing agent for organic synthesis reactions.
The preparation method of Camphoric anhydride is usually to react camphor with nitric acid to generate camphor nitrate, and then undergo an acylation reaction to obtain camphor anhydride. The specific preparation steps and conditions can be adjusted according to requirements and reaction conditions.
Regarding safety information, Camphoric anhydride dust is irritating to eyes and skin, direct contact should be avoided. At the same time, it is also a flammable substance and should be used in a well-ventilated place and avoid contact with open flames, high temperatures and oxidants. Wear appropriate personal protective equipment such as lab gloves, goggles and protective clothing when used. In addition, Camphoric anhydride should be stored in a dry, cool place, away from fire and flammable materials. If ingestion or contact, seek medical attention promptly.
