Chemical Structure
Basic Info
DL-Lactic acid is additionally referred to as 2-hydroxypropionic acid and α-hydroxypropionic acid. There is an asymmetric carbon atom in the molecular framework, developing 2 optical isomers, d-body, l-body and racemic body dl-body, with a total amount of 3 optical isomers. In 1780, Scheele acquired this product in yogurt, hence the name lactic acid.
There are right-handed and racemic bodies in human and animal meat tissues, while the left-handed body is a regular metabolite of creatures. It additionally exists naturally in fruits such as poppy, apple, and tomato juice. Readily offered products, whether gotten by fermentation or synthesis, are all racemic bodies. As a result of the presence of hydroxyl and carboxyl teams in the particle, this item has the effects of these two practical teams, creating carboxylic acid esters with acid anhydrides, lactic acid esters with alcohols, and salts with sodium, calcium, ferrous ions; since this product has both hydroxyl and carboxyl groups, it can undertake self-esterification to generate linear polyesters, and also cyclic substances, that is, cyclic dimer lactide. Under slow oxidation conditions, this product can generate pyruvic acid. When heated up to above 250 ° C, it will damage the chain and disintegrate to generate acetaldehyde, launching co2 and water. It can react with ammonia or amine to generate lactic acid amide. Along with self-esterification, the hydroxyl and carboxyl teams of this item can additionally participate in the reaction at the same time, for example, reacting with aldehydes or ketones can generate cyclic acetals.
