Oxalic Acid Anhydrous Factory 98% grade ,White powder. No smell. 110 ~ 120 ℃ sublimation. Can weather in high heat and dry air. The solubility in water: 90g/L (20 ° C), extremely soluble in ethanol, and soluble in glycerin. Insperfolid in benzene, chloroform and petroleum ether. The pH of the 0.1mol/L solution is 1.3. 

• Specification:

• Package:  In 25KG kraft paper bag or 50KG Fiber Drum.

• Description:

Oxalic Acid Anhydrous Factory 98% grade is toxic, can be soluble in hot water, ethanol, and glycerin. It is slightly soluble in ether. It is harmful to the eyes and has a corrosive effect on the skin. After the water, it has a stronger effect.

During storage, it should be isolated from moisture, rainproof, and oxidant and alkaline substances. The stored temperature is not higher than 40 ° C. To prevent contact with food, you should stay away from the living area, and it should not be installed on the deck when loading.

Although Oxalic Acid Anhydrous Factory 98% grade is not flawed, it can be used in water and sand when it causes burning. If you enter the eyes or touch the skin, rinse it with a lot of water, and you should take it to the hospital for treatment by mistake.

Synthesize oxalic acid diobarium ester, with industrial anemne, pyrine, trianglene, albinol, etc., including the following steps: dissolved the raw material in a certain amount of organic solvents, in boron anhydride, coke boric acid or Polaric acid or titanium sulfate, titanium titanic acid and other catalysts respond to a certain period of time at a certain temperature with hydraulic acid at a certain temperature. Filtering the water -free oxalic acid that has not reacts with the reaction several times. Then distille with water vapor to remove the unresponsive raw ingredients and trianglene and a small number of by -products with thick products, and then degrade the diobioxyl ester of the oxalic acid. This reaction can use organic solvents such as aromatic hydrocarbons and branches of alkane as the reaction medium. The present invention uses conventional heating, mild conditions, easy operation, easy to separate raw materials, less side reactions, and high product revenue.
