text: A process for the production of tartaric acids which comprises oxidizing a carbohydrat in an aqueous solution with nitric acid with formation of dextro and meso tartaric acids and oxalic acid, separating oxalic acid from liquid, precipitating dextro and meso tartaric acids and residual oxalic acid through the addition of zinc carbonate to about 60%70% neutralization and in heated condition, separating thus precipitated zinc salts, and converting the zinc dextro and meso tartrates into the corresponding acids by reaction with oxalic acid.
