1, 4-dioxane ring manufacturer for you to introduce 14 dioxane ring storage conditions!

14 dioxane storage Precautions Usually commercial plus stabilizer. Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the warehouse should not exceed 37℃. The package should be sealed and not in contact with air. It should be stored separately from oxidant, reducing agent and halogen, and should not be mixed. It should not be kept long enough to avoid deterioration. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that are prone to spark. The storage area should be equipped with leak emergency treatment equipment and suitable holding materials.

[Stability] :

1. Chemical properties: similar to general saturated ether, it is a relatively stable compound. The formation of explosive peroxides under the action of oxygen in the air, especially when exposed to scattered light. Stable to alkali, metallic sodium and weak acid. Strong acids and oxidants break ether bonds at high temperature and pressure to open rings. When combined with hydrogen halide, 1, 2-dihalide ethane and glycol are formed. When heated, it reacts with concentrated sulfuric acid to produce 2-methyl-1, 3-dipentane, etc.

2. It is heated with acetic acid or acetic anhydride to produce glycol diacetate. It can form complexes with halogens, nitric acid, sulfuric acid and other inorganic compounds. For example, oxygen compounds such as C4H8O2Br2(m.p. 66℃), C4H8O2I2(m.p. 84℃) and C4H8O2Cl2 were formed with halogens, and C4H8O2H2SO4(m.p. 101℃) were formed with sulfuric acid. Complexes LiCl· C4H8O2· H2O, BF3· 2H2O· C4H8O2 can also be formed with lithium chloride or boron trifluoride. With the catalysis of palladium, rhodium, nickel and other metals, dioxane conducted isotope exchange between deuterium and ether. Dioxane reacts with tetranitromethane in bright yellow color. This reaction can be used to test dioxane.

3. It is microtoxic. The toxicity is 2~3 times stronger than ether. Poisoning at the most initial appearance of anesthesia, vomiting, frequent urination after reduced urine, eventually stopped urination. At the same time, increased blood urea, sleepiness, lethargy, 2~3 days after death. Long-term exposure or inhalation of its vapor can irritate the eyes, nose, throat and lungs, and damage the liver, kidney, brain and skin. The maximum allowable concentration in the workplace is 360mg/m3, and above 720mg/m3 can cause symptoms such as headache and stomach pain. Dioxane can be absorbed through the skin and toxic, contact the skin should be washed with plenty of water and wash with soap.

5. Forbidden compound strong oxidant, strong reducing agent, halogen

6. Avoid exposure to light and air conditions

7. Polymerization harms non-polymerization
