Hunan zirconium iron import and export Co., Ltd is a professional research, development and production of zirconium silicate & titanium dioxide backbone members of enterprise, the local well-known entrepreneurs and professional senior engineers in the party′s call for "safety and smoothness low carbon environmental protection" and the support of the bold innovation on traditional production equipment and technology, on the basis of reducing the product cost make the product quality to achieve the same industry leading level.
Methanol, also known as hydroxymethane, is an organic compound and the simplest saturated monohydric alcohol. Its chemical formula is CH3OH/CH4O, of which CH3OH is a simplified structural formula, which can highlight the hydroxyl group of methanol. The CAS number is 67-56 -1, the molecular weight is 32.04, and the boiling point is 64.7°C. Because it was first discovered in dry distillation wood, it is also called "wood alcohol" or "wood essence". The lowest dose of human oral poisoning is about 100mg/kg body weight, and oral intake of 0.3 to 1g/kg can cause death. It is used in the manufacture of formaldehyde and pesticides, and as an extractant for organic matter and a denaturant for alcohol.
