Thermal decomposition of some anhydride into milk

Melting point 18 ℃. Boiling point 122 ℃ (2kPa). Refractive index nD (20 ℃) ??1.4392. With water, ethanol, glycerin, insoluble in chloroform, carbon disulfide and petroleum ether. Heating under normal pressure, concentrated to 50%, the part becomes the lactic Calcium lactate  product often contains 10% to 15% of the milk anhydride. Lactic acid (alias: α hydroxy acid) Lactic Acid role of disinfection can be used for air disinfection, per cubic meter 1ml, diluted 10 times with water, set the evaporating dish heating evaporation, doors and windows closed for 30 minutes. CAS No.: 50-21-5 Lactic acid has two optical isomers, as L-and D, where L-naturally present in the human being, can be metabolized by the body. There are many derivatives of potassium lactate，  including salts and esters, salts, have a high solubility, is a good mineral supplements, but also a component of many drugs, its esters as a natural degradation advantages, are widely used in various kinds of industrial technology and everyday life.
