69288-29-5 - Introduction
5,7-eicosadiynoic ACID is an organic compound with the molecular formula C20H38O2. The following is a description of its nature, use, preparation and safety information:
Properties: 5,7-eicosadiynoic ACID is a white solid, insoluble in water at room temperature, but soluble in organic solvents, such as ether, chloroform and benzene. It has a high melting point and a high boiling point. It is a diynoic acid containing two terminal carbon-carbon triple bonds.
use: 5,7-eicosadiynoic ACID has a certain application value in the field of chemistry. It can be used as a starting material for the synthesis of other organic compounds, such as polymers, surfactants, polyesters and fluorescent dyes. In addition, it can also be used in biomedical research and pharmaceutical fields.
preparation method: 5,7-eicosadiynoic ACID can be prepared by reacting N-Pentyne with iodine and hydroformic ACID in the presence of a base catalyst. The specific steps include first reacting Pentyne with hydroiodic acid to obtain pentodopentane, and then obtaining 5,7-eicosandiynoic acid through alkali-catalyzed deiodination, finally, dilute hydrochloric acid or sulfuric acid is used to hydrate it to obtain the target product.
SAFETY INFORMATION: There is limited information regarding the safety of 5,7-eicosadiynoic ACID, but care should be taken to follow safe operating procedures depending on how the regular chemical is handled. It may be irritating to the eyes and skin, so appropriate protective measures should be taken when using it, such as wearing chemical safety glasses and protective gloves. In storage and handling, should be away from fire and high temperature environment, and maintain good ventilation. At the same time, avoid contact with strong oxidants and strong acids to avoid dangerous reactions. If necessary, reference can be made to the relevant chemical safety data sheets or hazardous waste disposal. In any case, carefully read the safety instructions of the product and follow the correct operating procedures before use.
