Propanedioic acid, bis(phenylmethyl) ester - Introduction
Dibenzyl malonate, chemical formula C12H10O4, is a colorless to slightly yellow liquid. The following is a description of some of the properties, uses, methods and safety information of Dibenzyl malonate:
Nature:
- Dibenzyl malonate has good solubility and is soluble in many organic solvents, such as ethanol, ether, benzene, etc.
-It has a lower boiling point and vapor pressure.
- Dibenzyl malonate has a certain pungent odor and is irritating to the skin and eyes.
Use:
- Dibenzyl malonate is commonly used as an intermediate for synthetic materials and spices, and has fruit-like and Hawthorn-like characteristics in odor.
-It can be used to prepare resins, such as maleic acid styrene resins, used as plasticizers and stabilizers for paints and coatings.
- Dibenzyl malonate can also be used as pharmaceutical intermediates, such as synthetic brain-refreshing agents and fungicides.
Method:
The common preparation method of-Dibenzyl malonate is to react phenylethyl alcohol with maleic anhydride, and perform esterification reaction in the presence of acid or alkali catalyst.
Safety Information:
- Dibenzyl malonate is irritating and corrosive and should be avoided in contact with skin and eyes.
-During use, avoid inhaling its steam or dust, and operate in a well-ventilated place.
-Should be stored in a cool, ventilated and dry place without fire source, away from fire source and oxidant.
