Oxalic Acid

Description

Alias: sulfur and urease Formula: CH4N2S Weight: *6.*2 Product description: pure products for FangJing shape powder, colorless oblique with bitter, g/Cm3 density 1.*0, melting ******8 degrees Celsius, decompression and in ******0 degrees sublimation, soluble in water, alcohol can melt in heating, microscopic melt in ether. In the air when ChaoXie easy, heating, when molten part on heterogeneous formed ammonium leaching of sulfur. Methods: we produce thiourea department adopts the alkaline hydrolysis of limestone absorb exhaust h2s fluid of limewater. Obtain sulfur cyanide leaching, reoccupy sulfur calcium lime nitrogen condensation and calcium and filter cake of glycosylthioureas, after the solution of glycosylthioureas, concentration, crystallization, dry unit operation after drying packaging products, obtained and finished products. Main purpose: 1, thiourea used in pharmaceutical industry, such as manufacturing, inhibit thyroid disease 噻唑 sulfonamides drugs and pig powder and feed additive, 2, the textile industry is used as a condiment and dressing metal mineral industry as flotation agents, 3, printing and dyeing industry for dyeing auxiliaries, 4 rubber industrial used rubber sulfide accelerator, 5, photographic camera contrast and industrial used toner, 6, plating industry as electro-plating additive, 7 and metallurgy in a copper and gold for the production, 8 and coatings used for resin powder materials; compression 9, daily chemical industry LengTang used to produce pure, *0 and organic industrial used in the production of urea so2, *1 and analytical chemistry as chemical reagent, *2, in addition, also can be used for cleaning power plant boiler, pressure ShaiTu etc. Packing specification: use lined with plastic sheets, plus woven plastic packaging, containing *5kg or *0 kg. Note: 1, thiourea medium toxicity, corrosion, should according to toxic chemicals skin prescribed shipment. 2, should be stored in a cool, dry and ventilated warehouse, heat and moisture.
