Pure lactic acid is a colorless liquid, is a colorless to pale yellow liquid. Odorless, hygroscopic. The relative density of 1.2060 (25/4 ℃). 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%, part of the anhydride into milk, thus products often contain 10% -15% of the milk anhydride.

The economic value of lactic acid and calcium lactate
Wastewater pollution has been brewing production process must face and solve a major problem. After years of practice and exploration, successfully developed a " harmless , effective treatment discarded lees technology, to achieve a" wine - Grains - Complex worse - green boiler - white carbon black project "
Waste recycling industry chain contaminants . Ethyl lactate not only solve the problem of pollution Brewers Grains , Grains achieve zero emissions , but also spent grains from the wastes, pollutants into energy , which produces silica having an economic value and re bad wine, elongated main wine industry chain at the same time , the use of bottom pot yellow water extraction of lactic acid and calcium lactate technology, not only effectively solve the winemaking end of the pot of yellow water pollution problems ,ferrous lactate emissions of organic pollutants , but also the end of the pot yellow water of wine , produced with lactic acid and calcium lactate economic value , and truly turning waste into treasure.
