Tributil fosfat (TBP)

Proprjetajiet

♦ Proprjetajiet tas-Solvent

TBP huwa solvent effettiv għal firxa wiesgħa ta 'komposti organiċi. It is miscible with

various organic solvents, inklużi l-idrokarburi, alkoħol,u eteri. This makes it

suitable for use in extraction processes, where it can selectively dissolve and extract

specific compounds from mixtures

♦ Estrazzjoni selettiva tal-metall

TBP għandu affinità għolja għall-joni tal-metall, particularly those with high charge densities.

Jifforma kumplessi stabbli b'jonji tal-metall, enabling the extraction and separation

of metals from aqueous solutions. This property is extensively utilized in hydrometallurgy,

such as the extraction of uranium from uraniumore or the recovery of valuable metals

from spent nuclear fuel.

♦ Ritardant tal-Fjammi

TBP juri proprjetajiet ritardanti tal-fjammi, making it useful in applicationswhere fire

resistance is desired. Isib użu bħala ritardant tal-fjammi fil-plastik,polimeri, and other

materials to improve their fire safety characteristics.

Applications

♦ Idrometallurġija:

TBP jintuża b'mod estensiv fl-estrazzjoni u l-irkupru ta 'jonji tal-metall minn minerali, konċentrati,

u soluzzjonijiet milwiema. It plays a crucial role in the production of nuclear fuel, where it

facilitates the extraction of uranium from uranium ore. It is also employed in the

reprocessing of spentnuclear fuel to recover valuable metals like uranium and plutonium.

♦ Solvent u Proċessi ta' Estrazzjoni

Il-proprjetajiet eċċellenti tas-solvent ta 'TBP jagħmluha adattata għall-użu f'diversi proċessi ta' estrazzjoni.

Huwa impjegat fis-separazzjoni u l-purifikazzjoni ta 'komposti organiċi, such as the

extractionof rare earth elements, separazzjoni ta' aċidi organiċi, and purification of

pharmaceuticalintermediates.

♦ Applikazzjonijiet li jwaqqfu l-fjammi

Minħabba l-proprjetajiet ritardanti tal-fjammi tiegħu, TBP is utilized in the production of flame-retardant

plastics, polimeri, u kisi. It helps to reduce the flammability and improve the fire

safety of these materials.

♦ Proċessi Industrijali

TBP isib użu bħala anti-fowmaġent ing, plastiċizzant, u tixrib agent in industrial

applications. Jista 'jistabbilizza l-fluwidi tal-proċess, tnaqqas il-formazzjoni tal-fowm, and enhance the

performance of certain

manufacturing processes.

Production Process

 

♦ Preparazzjoni ta' Reactants

Ossiklo fosfruride (POCl3) u butanol (C4H9OH) are obtained as starting materjali.

POCl3 is typically synthesized by the reaction of phosphorus trichloride (PCl3) with oxygen

or chlorine.

♦ Reazzjoni

Ir-reazzjoni bejn POCl3 u butanol isseħħ fil- preżenza ta’ katalizzatur, usually

a strong acid such as sulfuric acid (H2SO4). The reaction is an esterification process,

fejn l-hydroxyl (-OH) group of butanol reacts with the phosphorusoxychloride to

form the ester, Tributil Fosfat (TBP), along with the release of hydrogen chloride

(HCl) bħala prodott sekondarju.

♦ Purifikazzjoni

Wara r-reazzjoni, it-TBP mhux raffinat huwa miksubd. Tipikament hija taħlita ta 'TBP, unreacted

butanol, u impuritajiet oħra. The crude TBP is then subjected to purification steps to

remove these impurities. Tekniki ta' purifikazzjoni jistgħu jinkludu distillazzjoni, estrazzjoni tas-solvent,

jew proċessi oħra ta' separazzjoni biex jinkiseb TBP pur.

♦ Raffinar u Kontroll tal-Kwalità

It-TBP purifikat huwa aktar raffinat biex jissodisfa rekwiżiti speċifiċi ta 'kwalità. This may involve

additional purification steps, bħal filtrazzjoni jew adsorbiment, to remove any remaining

impurities and ensure the desired purity of the final product. Miżuri ta' kontroll tal-kwalità, such

as testing for chemical composition and physical properties, are employed to ensure that the

TBP meets the specified standards.

♦Ippakkjar u Ħażna

Ladarba t-TBP ikun ġie prodott u rfinat, huwa ppakkjat f'kontenituri xierqa, such as

drums or tank farm.

Spezzjoni

♦ Proċess ta 'spezzjoni

1. Spezzjoni deħlin: Il-materja prima ewlenija, bħal fosfru trichloride u n-butanol,

huma spezzjonati għall-kontenut tagħhom, dehra u proprjetajiet ewlenin oħra.

2. Spezzjoni ta 'tmigħ: il-prinċipju ta ' l-għalf tal-materja prima huwa 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. Teħid ta 'kampjuni tal-lott fil-proċess tal-produzzjoni: Matul il-proċess tal-produzzjoni, the main indexes of

each batch of products: il-kontenut u l-valur tal-aċidu se jiġu eżaminati tliet darbiet f'perjodi ta 'żmien differenti.

4. Spezzjoni tal-Ħażna: Kull lott (6 tunnellati) jiġi spezzjonat qabel il-ħażna.

5. Spezzjoni 'l barra: Skond il-kwantità mitluba mill-klijenti, the products will be

sampled and inspected.

6. Spezzjoni qabel il-ġarr: skond il-ħtieġa tal-klijent, third party inspection can be

carried out on the products before shipment.
