Glycerin, alias glycerol, colorless, odorless, sweet, clear and viscous liquid, is an organic matter. It can absorb moisture from the air and also absorb hydrogen sulfide, hydrogen cyanide and sulfur dioxide. Insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oils. Because glycerin is widely used in industrial, cosmetic, food, etc., glycerol is usually used.
The following Bite Chemicals, which supply glycerol, will take you through the safety aspects of glycerol:
Closed operation, pay attention to ventilation, the operator must be specially trained and strictly abide by the operating procedures. Operators are advised to wear self-priming filter gas masks (half masks), chemical safety glasses, anti-poisoning overalls, and rubber gloves. Keep away from fire, heat, and smoking in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam from leaking into the workplace air. Avoid contact with oxidants and acids. Lightly load and unload during handling to prevent damage to packaging and containers. Equipped with the corresponding amount of fire equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.
Store in a cool, ventilated warehouse. Keep away from fire and heat. It should be stored separately from oxidants and acids, remember to mix and store. Equipped with the corresponding amount of fire equipment. The storage area should be equipped with leaking emergency treatment equipment and suitable containment materials.
How glycerin is mixed with strong oxidants (such as chromium trichloride, potassium chlorate, potassium permanganate) may explode. The reaction rate is low in dilute solutions and there are several oxidation products produced. When exposed to light or basic cerium nitrate or zinc oxide, glycerol turns black.
If iron contaminants are doped in it, the mixture containing phenol, salicylic acid, and tannic acid will turn black. Glycerol forms a boric acid complex (glycerol borate) which is more acidic than boric acid.
Health hazard: Edible is toxic to people. Ingestion: Drink warm water and induce vomiting. It has a stimulating effect on eyes and skin.
The oral toxicity of mice was KD50=31,500 mg/kg, and the LD50 of intravenous administration was 7,560 mg/kg.
Explosion hazard: This product is flammable and irritating.
Hazardous characteristics: In case of fire, high heat and flammable.
