草酸氢钾 制备方法及用途

制备方法

将12.6g二水合草酸(0.1mol)溶于300mL水中。用18.4g一水合草酸钾(0.1mol)溶于100mL水中。然后在3℃下将草酸钾水溶液加到草酸水溶液中,在0℃放置24h,析出的晶体即为草酸氢钾一水合物。

    label when possible. Avoid contact with skin and eyes
    Storage        Keep container dry. Keep in a cool place. Ground all equipment containing material. Keep container tightly    
    closed. Keep in a cool, well-ventilated place. Combustible materials should be stored away from extreme heat
    and away from strong oxidizing agents.

Section 8. Exposure Controls/Personal Protection
    Engineering Controls        Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below    
    recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
    airborne contaminants below the exposure limit.
    Personal Protection        Splash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.    
    Gloves.
    Personal Protection in Case of Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
    a Large Spill        to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist
