PRODUCTION OF L-(+)-TARTARIC ACID:
The L-(+)-Tartaric acid isomer of tartaric acid is industrially produced in the largest amounts.
L-(+)-Tartaric acid is obtained from lees, a solid byproduct of fermentations.

The former byproducts mostly consist of potassium bitartrate (KHC4H4O6).
This potassium salt is converted to calcium tartrate (CaC4H4O6) upon treatment with calcium hydroxide (Ca(OH)2):

KH(C4H4O6) + Ca(OH)2 → Ca(C4H4O6) + KOH + H2O
In practice, higher yields of calcium tartrate are obtained with the addition of calcium sulfate.
Calcium tartrate is then converted to tartaric acid by treating the salt with aqueous sulfuric acid:
Ca(C4H4O6) + H2SO4 → H2(C4H4O6) + CaSO4

STORAGE OF L-(+)-TARTARIC ACID:
storage

INCOMPATIBILITIES OF L-(+)-TARTARIC ACID:
L-(+)-Tartaric acid is incompatible with silver and reacts with metal carbonates and bicarbonates (a property exploited in effervescent preparations).

PRODUCTION METHODS OF L-(+)-TARTARIC ACID:
L-(+)-Tartaric acid occurs naturally in many fruits as the free acid or in combination with calcium, magnesium, and potassium.
Commercially, L-(＋)-tartaric acid is manufactured from potassium tartrate (cream of tartar), a by-product of wine making.
Potassium tartrate is treated with hydrochloric acid, followed by the addition of a calcium salt to produce insoluble calcium tartrate.
This precipitate is then removed by filtration and reacted with 70% sulfuric acid to yield tartaric acid and calcium sulfate.

STEREOCHEMISTRY OF L-(+)-TARTARIC ACID:
Naturally occurring form of the acid is dextro tartaric acid or L-(+)-tartaric acid (obsolete name d-tartaric acid).
Because it is available naturally, L-(+)-Tartaric acid is cheaper than its enantiomer and the meso isomer.
The dextro and levo prefixes are archaic terms.

Modern textbooks refer to the natural form as (2R,3R)-tartaric acid (L-(+)-tartaric acid), and its enantiomer as (2S,3S)-tartaric acid (D-(-)-tartaric acid).
The meso diastereomer is referred to as (2R,3S)-tartaric acid or (2S,3R)-tartaric acid.

Dextro and levo form monoclinic sphenoidal crystals and orthorhombic crystals.
Racemic tartaric acid forms monoclinic and triclinic crystals (space group P1).
Anhydrous meso tartaric acid form two anhydrous polymorphs: triclinic and orthorhombic.

Monohydrated meso tartaric acid crystallizes as monoclinic and triclinic polymorphys depending on the temperature at which crystallization from aqueous solution occurs.
Tartaric acid in Fehling's solution binds to copper(II) ions, preventing the formation of insoluble hydroxide salts.

L-(+)-tartaric acid, can participate in several reactions.

HO2CCH(OH)CH(OH)CO2H + H2O2 → HO2CC(OH)C(OH)CO2H + 2 H2O
Dihydroxymaleic acid can then be oxidized to tartronic acid with nitric acid.
