DL-말산 C화학적 특성, 용도, 생산

개요

White or nearly white, crystalline powder or granules having a strongly acid taste. One g dissolves in 0.8 mL of water and in 1.4 mL of alcohol. Its solutions are optically inactive. It melts at about 130°.

화학적 성질

white crystalline powder

용도

DL-malic acid is primarily used in the food and beverage industry.

Purification Methods

Crystallise the acid from acetone, then from acetone/CCl4, or from ethyl acetate by adding pet ether (b 60-70o). Dry it at 35o under 1mm pressure to avoid formation of the anhydride. [Beilstein 3 IV 1124.]
