Production methods of L(+)-Tartaric Acid;CAS:87-69-4 1. The tartar made from the manufacture of wine is converted into calcium salt and then decomposed with a slightly more dilute acid. Or in the case of maleic acid and hydrogen peroxide, it is converted to epoxy succinic acid at a certain temperature and then hydrolyzed dl-tartaric acid. It can also be obtained by chemical synthesis of epoxysuccinic acid, which is obtained by the action of cyclokinase, which is contained in the bacteria of norcaria succinate.
2. Add distilled water to industrial tartaric acid and steam and stir to dissolve it. Let stand after adding suitable amount of activated carbon, fully mixing, filtration, the filtrate is heated to concentrate on the surface of the conjunctiva, strike the suction filter and filtrate the cooling crystallization, after being completely, crystal with a small amount of distilled water to wash the shower after 30 ~ 40 ℃ under tile dry to be stained with a spoon. If control active carbon decoloring temperature is 80 ℃, 80 ℃ after filtering reduced pressure concentration, cooling crystallization, will be the crystallization of recrystallization refined in the iron container under the low temperature drying, available right handed tartaric acid (L (+) tartaric acid] finished products.
L(+)- tartaric acid is widely used as an acidic agent for drinks and other foods for wine, soft drinks, candies, breads, and some gelatinous desserts.
