リン酸ジブチル（DBP）

♦ 簡単な紹介

リン酸ジブチル (DBP) is an organic compound . It is a clear,

colorless liquid that is soluble in organic solvents like ethanol

and ether.

♦ 応用

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. 可塑剤: Dibutyl phosphate acts as a plasticizer, which means it

is added to plastics and resins to improve their flexibility, 耐久性,

and processing characteristics. It helps to enhance the flow and

workability of the materials during manufacturing processes.

3. 難燃剤: Dibutyl phosphate is used as a flame retardant additive

in plastics, コーティング, 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

ウラン. It effectively extracts uranium from ores and solutions during

the uranium mining and nuclear fuel production industries.

♦ 梱包と保管

パッケージ: Once the DBP has been produced and refined, にパッケージ化されています

適切な容器, such as Plastic Barrels or IBC drum.

ストレージ: If stored correctly and kept in the original sealed container, the product

has a shelf life of at least 24 月. 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.
