Packing & Storage
| Packing | Large packaging: plastic drums (cans), the upper part of the container should have a pressure-reducing valve or vent, there should be at least a 10% margin in the container, and the net weight of each barrel (tank) should not exceed 50 kg. Reagent packaging: plastic bottles, then individually packed into plastic bags, and packed in calcium plastic boxes. | |||||||
| Storage | Store in a cool and ventilated warehouse.Keep away from fire and heat sources.It should be stored separately from oxidants, acids, and alkalis, and should not be mixed.Equipped with corresponding varieties and quantities of fire fighting equipment.The storage area should be equipped with suitable materials to contain leaks. | |||||||
| Transportation | During transportation, make sure that the container does not leak, collapse, fall, or damage. It is strictly prohibited to transport in parallel with acids, flammable substances, organic matter, reducing agents, spontaneously combustible items, and flammable items in case of moisture. | |||||||

| SYMPTOMS | PREVENTION | FIRST AID | |
| Inhalation | Inhalation can cause respiratory irritation | Respirators should be worn. It is recommended to wear self-contained breathing apparatus when necessary. | If inhaled, move the patient to fresh air. If breathing stops, perform artificial respiration. Consult a doctor. |
| Skin | Skin irritation or skin corrosion | Wear protective gloves and rubber oil-resistant gloves. | Take off contaminated clothing and rinse your skin thoroughly with plenty of running water. |
| Eyes | May cause eye burns | Wear chemical safety protective glasses. | Rinse thoroughly with plenty of water for at least 15 minutes and consult a doctor. |
| Ingestion | Swallowing may be harmful | Do not eat, drink, or smoke during work. Wash hands before eating. | Never feed anything through the mouth to the unconscious person. Rinse your mouth with water. Consult a doctor. |
Synthetic Route
| Isopropanol method: The isopropanol method uses peroxide as the inducing agent and uses air or oxygen to oxidize the liquid phase of isopropanol to generate hydrogen peroxide and acetone. The oxidized product is separated from organic matter and water by an evaporator, and then extracted and purified by an organic solvent to obtain hydrogen peroxide, while acetone is produced by-product. |
