Bis-(2,4,4-trimethylpentyl)-phosphinic Acid - Introduction
Diisooctylphosphinic acid is an organophosphorus compound with the chemical formula [(CH3)2C(CH3)2]2P(OH). The following is an introduction to its nature, use, preparation and safety information:
Nature:
-Appearance: Diisooctylphosphinic acid is generally colorless to yellow liquid, similar to the appearance of the paste.
-Solubility: It is soluble in organic solvents, such as ether, ethanol and benzene.
-Stability: Diisooctylphosphinic acid is relatively stable at room temperature, but may decompose at high temperature.
Use:
-Catalyst: Diisooctylphosphinic acid can be used as a ligand for negative oxidants and is used for catalytic reactions in organic synthesis, such as asymmetric hydrogenation, nucleophilic addition reactions of alkenes catalyzed by nitrogen and nitrogen benzene.
-Fluorescent probe: Diisooctylphosphinic acid has certain fluorescent properties and can be used as a fluorescent probe in the field of biochemical analysis.
Preparation Method:
The preparation of Diisooctylphosphinic acid is usually carried out by the following steps:
1. trimethyl pentyl alcohol was synthesized from trimethyl pentyl phosphine chloride (CH3)3 CPCl2.
2. reacting trimethylpentylphosphine chloride with water to generate trimethylpentylphosphonic acid (CH3)3CP(O)OH.
Safety Information:
- Diisooctylphosphinic acid is less toxic. But as an organic phosphorus compound, it may cause some degree of harm to the human body.
-When using Diisooctylphosphinic acid, you need to take appropriate laboratory safety measures, such as wearing protective glasses and gloves, and operating in a well-ventilated place.
-Avoid direct contact with the skin to avoid irritation or allergic reactions.
-When disposing of waste, it needs to be disposed of in accordance with local regulations.
