D-Tartaric acid is mainly present in the form of potassium salt in a variety of plants, fruits. There also a small amount present in free species. In the field of practical application of tartaric acid, they usually mainly use the L(+)tartaric acid or its salts. The industrial way to get L(+)tartaric acid is through fermentation of glucose; raceme fumaric acid can be obtained with the potassium permanganate oxidation.
As to its usage, it is usually applied in many ways. It could be used as colour spectrum analysis reagent and screening agent; It could also used as pharmaceutic resolving agent, food additives, biochemical reagents; It is widely used in food industry, such as beer foaming agent, food acidity regulations, Flavoring agent and also in soft drink, sweet, fruit juice, ferment powder and others.
When you are dealing with this chemical, you should be very careful and then take some measures to protect yourself. Being a kind of irritant chemical to eyes, respiratory system and skin, it may cause inflammation to the skin or other mucous membranes. Therefore, you should take the following instructions. Wear suitable protective clothing, gloves and eye/face protection, and if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
Additionally, you could convert the following datas into the molecular structure:
