English Name : Ethylene diamine tetraacetic acid (EDTA) Molecular Fomula : C10H16N2O8 Molecular Weight : M=292.24 CASNo. : 60-00-4 Properties : white crystal powder melting point 240(decomposition) insoluble in cold water ,alcohol and general organic solvent, slightly soluble in hot water, but soluble in sodium hydroxide, sodium carbonate and ammonia solution. An agent for complexation, EDTA is mainly used for water treatment, as an additive to detergent, a chemical for photography, paper-making and oil-field. It is also used as detergent for boiler cleaning and reagent in chemical analysis. 1. High molecular chemical industry: EDTA is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre production. 2.Daily chemicals: EDTA is used as additive to detergent, skin cream and hair-conditioner. 3.Paper-making: EDTA is used for treating the steamed fibre. It will promote the whiteness of paper and reduce the incrustation in the steamer. 4.Pharmaceutical industry: Through cyclopolymerization with methyl amide, EDTA is made into ethyl amide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin. 5. Textile dyeing and printing: EDTA will promote colour ability of the dyestuff and brightness of the dyed fabric. Package of Disodium edta zinc chelated Packing: 25KG/bag , Pearly membrane compound bag, with PE inside or according to the customers demand. Storage: Stored in the dry and ventilated inside storeroom, prevent direct sunlight, slightly pile and put down.

Ammonia is a colorless gas. It may be compressed and cooled to a colorless liquid. Ammonia is the compound formed by the chemical combination of the gaseous elements nitrogen and hydrogen. Ammonia is a highly reactive chemical, forming ammonium salts in reactions with inorganic and organic acids. Industrial ammonia is used for a wide variety of applications in varying quantities. Product Name Ammonia Chemical Formula NH3 Hazard Class 2.3 Molecular Weight 17.031 Boiling Point (C) -33.43 Boiling Point (F) -241.17 UN 1005 Density(kg/m³) 0.728 Density(lb/ft³) 0.044 Process: Industrial ammonia is purified by a filter into the electronic grade ultra-high purity ammonia. Annual output of ultra-high purity ammonia gas is 10,000 tons. Application: Ammonia(NH3)is used in 1. metal treating operations as nitriding, carbo-nitriding, bright annealing, furnace brazing, sintering, sodium hydride descaling, atomic hydrogen welding, and other applications where protective atmospheres are required 2. hydrogenation of fats and oils as a convenient source of hydrogen 3.manufacturing of alkalis, ammonium salts, dyes, pharmaceuticals, cuprammonium rayon, and nylon 4. rubber industry for stabilization of raw latex to prevent coagulation during transportation and torage 5. as a catalyst in the phenol-formaldehyde condensation and also in the urea-formaldehyde condensation to make synthetic resin 6.produce proteins and can be used to improve the protein content of low quality hay 7.semiconductor industry 8.production of blue and white LEDs (Light Emitting Diods) 9.In the field of novel optoelectronic materials, it is an important base material for GAN preparation by MOCVD technology.High purity ammonia or the preparation of nitrogen trifluoride, silicon nitride, the basic material, is the production of super high nitrogen raw gas.In addition, liquid ammonia is widely used in the semiconductor industry, the metallurgical industry, as well as other industries and scientific research that need to protect the atmosphere.
