N,N-DIETHYL-1,5-DIHYDRO-2,4,3-BENZODIOXA -PHOSPHEPIN-3-AMINE, TECH. - Introduction

O-xylylene N,N-diethylphosphoramidite, often abbreviated as LAP, is an organophosphorus compound. Its chemical structure contains o-xylylene (2,4, 3-benzodioxepane) and N,N-diethyl groups. The following is more information about LAP:

Nature:
-Appearance: LAP is a colorless to pale yellow liquid.
-Solubility: LAP is soluble in common organic solvents such as alcohols, ethers and chlorinated hydrocarbons.
-Melting point: The melting point of LAP is about -30 to -20°C.
-Boiling point: The boiling point of LAP is about 240 to 250°C.

Use:
LAP, as an organophosphorus compound, is commonly used in the following areas:
-Catalyst: LAP can be used as a catalyst, acting as a catalyst and reducing agent in organic synthesis reactions. It can provide a unique environment in transition metal catalyzed reactions that helps accelerate the reaction rate.
-Flame retardant: LAP has good flame retardant properties and is commonly used in flame retardant modification of materials such as plastics, rubber and textiles.

Preparation Method:
The synthesis of LAP is usually carried out by the following steps:
1. The p-xylene phosphoryl chloride and N,N-diethyl amine are reacted in an appropriate solvent.
2. After the reaction is completed, adjust the pH with an appropriate acid or alkali.
3. purification by distillation of solvent to obtain high purity o-xylylene N,N-diethylphosphoramidite.

Safety Information:
- LAP is an organophosphorus compound and should be handled with care to avoid inhalation, contact with skin, or ingestion.
-Wear chemical protective gloves and safety glasses during operation to ensure good ventilation.
-In the event of accidental exposure to LAP, immediately flush the affected area with plenty of water and seek medical help.
- LAP should be stored in a sealed container, away from fire and oxidant, and avoid contact with oxygen.
