Product Description
Diacetyl Tartaric Acid Esters of Mono- and Diglycerides occur over a range in appearance from sticky, viscous liquids through a fatlike consistency to a waxy solid, depending on the iodine value of the oils or fats used in their manufacture. They are the reaction product of partial glycerides of edible oils, fats, or fat-forming fatty acids with diacetyl tartaric anhydride. The diacetyl tartaroyl esters are miscible in all proportions with oils and fats. They are soluble in most common fat solvents, in methanol, in acetone, and in ethyl acetate, but are insoluble in other alcohols, in acetic acid, and in water. They are dispersible in water and resistant to hydrolysis for moderate periods of time. The PH of a 3% dispersion in water is between 2 and 3.
Usage:
L-Tartaric Acid is widely used as food, beverages and other sour agent. With its optical activity, L-Tartaric Acid as a chemical resolving agent to resolve DL-amino-butanol, anti-TB drug intermediates. L-Tartaric Acid is used for synthesis of tartaric acid derivatives as chiral pool. With its acidity, L-Tartaric Acid is used as a catalyst in the resin finishing of polyester fabric or a pH regulator oryzanol production. With its complex, L-Tartaric Acid is used in electroplating, desulfurization, acid.
