Read： 365 Time：11months ago Source：Transform the World with Simplicity

Disodium dihydrogen pyrophosphate (Disodium Pyrophosphate, DSPP) is a common chemical raw material, widely used in food additives, detergents, ceramics, medicine and other fields. Due to its chemical activity, it is necessary to comply with certain safety regulations during storage and transportation.

1. the properties of disodium dihydrogen pyrophosphate

disodium dihydrogen pyrophosphate is a white crystalline powder with strong hygroscopicity, easily soluble in water, and the solution is acidic. It will decompose at high temperature to produce phosphoric acid and sodium hydroxide, and has high reactivity with acid, alkali, metal ions, etc.

2. safety storage specifications for disodium dihydrogen pyrophosphate

1. Storage environment: Disodium dihydrogen pyrophosphate should be stored in a dry, cool, well-ventilated indoor environment, avoiding direct sunlight and high temperatures.
2. Storage container: A container with good sealing performance should be used for storage to prevent moisture absorption and pollution.
3. Storage identification: Obvious identification shall be set up in the storage area, indicating the name of the item, risk level, storage precautions and other information.
4. Storage management: A complete storage management system should be established, with detailed records of warehousing, outbound, and inventory, and regular inspections and maintenance.

3. of disodium dihydrogen pyrophosphate transport specification

1. transport packaging: disodium dihydrogen pyrophosphate should be packaged with packaging materials that meet the relevant standards to ensure that it will not leak or break during transport.
2. Transport identification: The transport package shall be marked with information such as the name of the article, hazard level and transport precautions.
3. Transport vehicles: Transport vehicles that meet relevant standards should be selected for transportation to ensure stability during transportation and avoid collisions and friction.
4. Transportation personnel: transportation personnel should have relevant qualifications and experience, understand the nature of disodium dihydrogen pyrophosphate and transportation precautions.

4. emergency measures

in the process of storage and transportation, in case of leakage, fire and other accidents, the following emergency measures should be taken:

1. Leakage treatment: in case of leakage, measures should be taken immediately to prevent diffusion, and corresponding absorption materials should be used to clean up the leakage.
2. Fire treatment: In case of fire, fire extinguishers, fire extinguishers and other fire fighting equipment shall be used immediately to extinguish the fire and report to the police in time.

5. other precautions

In the process of storing and transporting disodium dihydrogen pyrophosphate, the following should also be paid attention to:

1. Avoid mixing or mixing with acids, alkalis, metal ions and other items.
2. Personal protection should be paid attention to during operation to avoid contact with sensitive parts such as eyes and skin.
3. If the disodium dihydrogen pyrophosphate is found to be abnormal, measures should be taken in time to avoid adverse consequences.

In short, disodium dihydrogen pyrophosphate, as a common raw material for chemical production, needs to strictly abide by relevant safety regulations during storage and transportation to ensure the safety of personnel and goods.
