text: The process of recovering formed lactate of one of the alkaline earthmetals from fermented mashes, which produce lactic acid and to which a salt of such a metal has been added to control the acidity, which consists in adding to the mash a solvent comprising water and a member selected from the group consisting of ethyl alcohol, propyl alcohol and isopropyl alcohol, which when raised to the boiling point dissolves the lactate and soluble impurities into the so'ution and precipitates the insoluble Impurities, filtering off precipitated impurities -and then cooling the solution to precipitate out the lactate in the form of crystals while leaving the dissolved impurities in solution.

text: The process of recovering formed lactate of one of the alkaline earth metals from fermented mashes which produce lactic acid and to which a salt of such a metal has been added to control the acidity, which consists in adding strong unheated alcohol to the mash, and permitting the mash to set, so as to thereby cause the impure lactate to crystallize out, then dissolving the impure lactate crystals in a solvent comprising water and a member selected from the group consisting of ethyl alcohol, propyl alcohol and isopropyl alcohol raised to the boiling point so as to precipitate out any insoluble impurities and simultaneously dissolve the lactate and any soluble impurities present, filtering the solution and permitting the same to cool, so as to thereby cause the purified lactate to crystallize out of the solution in which the soluble impurities remain.
text: The process of purifying the lactate of an alkaline earth metal, which consists in dissolving the lactate in a solvent, selected from the group consisting of ethyl alcohol, propyl alcohol and isopropyl alcohol raised to the boiling point, and then filtering and permitting the solution to cool, so as to crystallize out the purified lactate.
text: The process of producing lactic acid from a lactate of one of the alkaline earth metals containing impurities which are not soluble in alcohol, which consists in dissolving the impure lactate in a solvent, selected fr"m the group consisting of ethyl alcohol, propyl alcohol and isopropyl alcohol of approximately 85% strength and water raised to the boiling point, thereby permitting the insoluble impurities to precipitate out and soluble impurities to go into solution, filtering off the insoluble impurities, adding sulphuric acid to the filtrate, removing the resulting sulphate by filtration, and then distilling off the alcohol and water to concentrate the free lactic acid therein.
