BIS(3,5-DIMETHYLPHENYL)PHOSPHINE OXIDE - Introduction
(XYL)2P(O)H ((XYL)2P(O)H) is an organophosphorus compound with the following properties:
1. Appearance: colorless liquid.
2. Solubility: Soluble in many organic solvents, such as dimethylformamide and acetonitrile.
3. Stability: It is relatively stable at room temperature, but it will react with oxygen in the air to produce oxidized phosphoric acid, which needs to be stored in an inert gas atmosphere.
4. Melting point and boiling point: melting point is about -15 ° C, boiling point is about 90-100 ° C.
(XYL)2P(O)H has some important applications in chemical synthesis, including:
1. As a catalyst: can be used in organic synthesis reaction of phosphating reaction and silanol reduction.
2. As a modifier: can be used to modify polyamide and phenolic resin and other polymer materials.
on the preparation method,(XYL)2P(O)H can be prepared by the reaction of phenyloxyphosphonic acid (EHS) and phenylethyl alcohol. The specific steps are as follows:
1. The reaction of phenylethyl alcohol and EHS in an inert atmosphere to generate the intermediate product phenyl chlorhydrin ether.
2. And then with triphenylphosphine Ester replacement reaction in an inert atmosphere to generate (XYL)2P(O)H.
The following safety precautions should be taken when using (XYL)2P(O)H:
1. Avoid contact with skin and eyes: If accidentally contact, should immediately rinse with plenty of water, and seek medical help.
2. Avoid inhaling aerosols or vapors: When using, ensure good ventilation. If inhalation occurs, please move to a place with fresh air immediately.
3. Avoid eating by mistake: This product is an organic phosphorus compound, which is toxic. Please keep it away from food and drinking water.
