Introduction
Dimethylmalonic acid (also known as succinic acid) is an organic compound. The following is an introduction to the properties, uses, preparation methods and safety information of dimethylmalonic acid:
Quality:
- Appearance: Dimethylmalonic acid is generally colorless crystalline or white powder.
- Solubility: Soluble in common solvents such as water, ethanol and ether.
Use:
- As an industrial raw material: It can be used to synthesize polyester resins, solvents, coatings and glues.
Method:
- A common method for the preparation of dimethylmalonic acid is obtained by hydroformylation of the ethylene additive. The specific step is to hydrogenate ethylene with formic acid to form glycolic acid, and then continue the esterification reaction between glycolic acid and formic acid to obtain the final product dimethylmalonic acid.
Safety Information:
- Dimethylmalonic acid is non-toxic, but care should still be taken to follow safe operating procedures in the laboratory and at the production site.
- Prevent inhalation of dust or contact with skin and eyes when using it, and wear appropriate protective gear (e.g., gloves and goggles).
- In case of accidental contact, rinse the affected area immediately with plenty of water and seek medical assistance if necessary.
