Properties and stability

Colorless prismatic crystals. Generally included1Molecular crystal water, in60℃ loses crystal water,110℃ sublimation. Melting point141-142℃,156-158℃ (rapid heating). Easily soluble in water and alcohol, anhydrous products can be soluble in ether, and those containing crystal water are insoluble in ether.

Storage method

This product should be sealed in Store in a cool place.

Synthesis method

Use diethyl malonate as raw material, first add bromine under light, and distill under reduced pressure to obtain bromine Propylene glycol diethyl ester. Then add potassium hydroxide solution and heat to reflux4hHydrolyze and neutralize with acetic acidpHfor5. Add barium chloride solution to generate barium hydroxymalonate salt. After acidification, it is distilled under reduced pressure, extracted with ether, and finally refined with acetic acid to obtain the finished product.

Purpose

Used in organic synthesis.
