For the current therapy of Alzheimer's disease (AD), which performances as memory loss and recognition ability disorders in the aged people, the drugs of Donepezil, Kabalatine, galantamine, and Memantine HCL always play an important role. 1, 3-Dimethyladamantane as the intermediate of Memantine HCL, the market requirement keeps increasing. In this regard, we enlarged our factory since 2010 to meet the worldwide increasingly demand of   1, 3-Dimethyladamantane  CAS 702-79-4. For now, we have 4 production lines, in which the capacity can be 30MT/month. Since 2010, we improved equipment and solved the wastes treatment facilities. Now the production is very stable and 1, 3-Dimethyladamantane quality very high. 60% is for export. Below are the product details. 1, 3-Dimethyladamantane CAS 702-79-4, Molecular Formula: C12H20 Molecular Weight: 164.29 Appearance: Colorless transparent liquid Boiling point: 201.5 °C Density: 0.886 g/mL...

Mechanism of Corrosion Inhibitor(Part 2)

  The effects of mixed corrosion inhibitors on the electrochemical process of corrosion are mainly manifested in: ①It reacts with the anodic reaction products to form insoluble substances, which are deposited closely on the metal surface to play the role of corrosion inhibition. The corrosion inhibition of phosphates such as Na3P04 and Na2HP04 to iron, magnesium, aluminum, etc. belongs to this type; ②Form colloidal substances, compounds that can form complex colloidal systems can be used as effective corrosion inhibitors, such as Na2Si03, etc.; ③Gelatin and gum Arabic can be adsorbed on the surface of aluminum, while pyridine and organic amines can be adsorbed on the surface of magnesium and magnesium alloy, so they can all play the role of corrosion inhibition. Our company provides  p-aminobenzamide . Physical and chemical mechanism of corrosion inhibitor From a physical and chemical point of view, the role of corrosion inhibitors can be divided into three types: oxide film f...
