Tartaric acid having two mutually symmetrical chiral carbon, having three isomers. Uses: used as antioxidant synergists, retarder, tanning agents, chelating agents, agents. Widely used in medicine, food, leather, textile and other industries. At low temperatures, low solubility in water, easy formation of insoluble calcium salts. Toxicity and Safety: Our food-grade nitric acid and low toxicity, its acidity, is corrosive to the teeth. With domestic production of concentrated nitric acid and an increasingly competitive market, there is a certain imbalance between regions, the future development of the domestic industry should form nitric single set of devices efficiently scale nitric acid, the new device should start more than 10 million tons / year; future new devices To the introduction of foreign technology and improve digestion and absorption, mainly adopt advanced technology to produce double-pressing method to achieve the installation of automated and technologically advanced technology; existing nitric acid plant should increase even lower organic fine chemical product development and professional management of nitric acid derivative, for Domestic TDI / MDI plant construction accelerated the situation, the region should take the initiative to establish the future business nitrate with expansion and new TDI / MDI corporate long-term strategic partnership, to avoid unnecessary duplication of domestic nitric acid plant construction, vertically integrated development model, to ensure the healthy development of China's benign nitrate industry.
