TERT-BUTYLPHOSPHONIC ACID - Introduction
tert-butylphosphonic acid is an organophosphorus compound with the chemical formula (CH3)3CPO3H2 with the following properties:
1. appearance: tert-butylphosphonic acid is colorless or yellowish liquid.
2. Solubility: It can be dissolved in water or in many organic solvents, such as alcohols, ethers and esters.
3. Acidity: It is a strong acid that can react with alkali to generate the corresponding salt.
4. Stability: relatively stable at room temperature, but decomposition may occur under high temperature or strong oxidation conditions.
The main uses of tert-butylphosphonic acid include:
1. Catalyst: It can be used as a transesterification catalyst, gas phase polymerization catalyst, alcohol condensation catalyst, etc.
2. Intermediate of phosphine chemical reaction: It can be used as a synthetic intermediate of phosphine compounds in organic synthesis.
3. Surfactants: tert-butylphosphonic acid and its salts can be used as surfactants, such as emulsifiers in polymer synthesis and coatings.
There are two main methods for the preparation of tert-butylphosphonic acid:
1. Phosphonylation reaction: prepared by reacting tributylphosphine with iodic acid.
2. phosphonation reaction: prepared by reacting tributylphosphine with benzoyl peroxide.
