Basic information

Nature: colorless to clarify oil liquid body. No smell. With water and ethanol mixed solution, and the release of large amounts of heat and heavy splash, acid should be added to the water gradually. Exposure to the air quickly absorb moisture, but also to seize the organic matter such as sugar, paper, cloth, wood and other water molecules and make it carbonation. When the water was 10, and the 98% was 3. At 340 DEG C for three decomposition of sulfur dioxide and water. The relative density of about 1.84 increase. Boiling point of about 2

Storage: sealed and dry preservation. In 801208 SCRC100216

The use of reagents for the analysis and laboratory, can be used to make analysis of the material into a soluble state. Barium, strontium, and lead. Can replace acid and volatile acid. Used for drying and melting point measuring instrument. Organic analysis and synthesis of water absorption. Sulfonated reaction. Condensation reaction. Mixed with nitric acid for nitration.
