Brief introduction

Dibutilfosfato (DBP) is an organic compound . It is a clear,

colorless liquid that is soluble in organic solvents like ethanol

and ether.

Apliko

1. Solvent: Dibutyl phosphate is used as a solvent in different applications,

including extraction processes, industrial cleaning, and as a reaction

medium in various chemical reactions.

2. Plasticizer: Dibutyl phosphate acts as a plasticizer, which means it

is added to plastics and resins to improve their flexibility, durability,

and processing characteristics. It helps to enhance the flow and

workability of the materials during manufacturing processes.

3. Flame Retardant: Dibutyl phosphate is used as a flame retardant additive

in plastics, coatings, and textiles. It helps to reduce the flammability

and improve the fire resistance properties of these materials.

4. Extraction Agent: Dibutyl phosphate is used as an extraction agent in

various processes, such as the separation and purification of metals, particularly

uranium. It effectively extracts uranium from ores and solutions during

the uranium mining and nuclear fuel production industries.

Packaging and Storage

Package: Once the DBP has been produced and refined, it is packaged into

suitable containers, such as Plastic Barrels or IBC drum.

Storage: If stored correctly and kept in the original sealed container, the product

has a shelf life of at least 24 months. Stainless steel and glass equipment

components as well as plastics such as polyethylene and polytetrafluoroethylene (PTFE)

have proven suitable. Materials suitable for sealing are polytetrafluoroethylene (PTFE)

and graphite. Ordinary steel is unsuitable because it reacts with dibutyl phosphate,

resulting in the formation of hydrogen.

Inspection process

1. Incoming inspection: The main raw materials, are inspected for their content, appearance and

other main properties.

2. Feeding inspection: The principle of raw material feeding is first-in-first-out, and the appearance

of the main raw materials is randomly inspected according to whether there is a big change in the

storage conditions before feeding.

3. Batch sampling in the production process: During the production process, the main indexes of

each batch of products: content and acid value will be examined three times in different time periods.

4. Storage Inspection: Each batch (10 tons) is inspected before storage.

5. Outbound inspection: According to the quantity demanded by customers, the products will be

sampled and inspected.

6. Pre-shipment inspection: According to customer’s requirement, third party inspection can be

carried out on the products before shipment.
