Ethyl acid G - Introduction
Monoethyl heptanedioate, chemical formula CH3COOC6H12COOH, is also abbreviated as GDE or GDAEE. The following is a description of the properties, uses, preparation and safety information of monoethyl heptanedioate:
Nature:
Ethyl heptanedioate is a colorless and transparent liquid with an oily appearance at room temperature. It has a pungent odor and low volatility. Monoethyl heptanedioic acid has high density and good solubility, and can be dissolved in a variety of organic solvents, such as alcohols, ethers and aromatic hydrocarbons. It is stable in air, but may react with strong oxidants.
Use:
Ethyl heptanedioate has a wide range of applications in the chemical industry. It is often used as a raw material for the synthesis of high-performance plastics, such as polyester resins, fibers and coatings. Monoethyl heptanedioic acid can also be used in the preparation of solvents, dye intermediates, coating plasticizers, rubber and plastic additives.
Preparation Method:
Monoethyl pimelate is usually prepared by esterification of pimelic acid and ethanol. The reaction can use a catalyst, such as sulfuric acid, lead chloride, etc., to increase the reaction rate and yield. The esterification reaction can be carried out at an appropriate reaction temperature to produce monoethyl heptanedioate and water, and monoethyl heptanedioate with higher purity can be obtained through water removal and product separation and purification processes.
Safety Information:
When using and storing monoethyl heptanedioate, the following safety precautions should be paid attention:
1. heptanoic acid monoethyl ester is irritating, should avoid contact with skin, eyes, etc., should wear protective gloves and goggles when using.
2. avoid inhalation of monoethyl heptanoate vapor, should be in a well-ventilated place of operation.
3. heptanoic acid monoethyl ester is flammable, should be away from open flame and heat source, storage to avoid high temperature environment.
4. heptanedioic acid monoethyl ester should be kept away from strong oxidants to avoid fire or explosion hazards.
5. If swallowed or accidentally entered the eye, seek medical attention immediately and bring a container or label of heptanedioic acid monoethyl ester.
