1. Physical and chemical properties:
1.1 Appearance: Colorless to yellow oil-linking liquid
1.2 Odour: Foul smell with rotten green grass
1.3 Solubility: Dissolving easily in organic solvents such as methylene dichloride, chloroform, ethyl ether etc, dissolving slightly in water.
1.4 Boiling point: 90-92°C,0.15-0.3mmHg
1.5 Stability: Its decomposition temperature is 170°C .It will be decomposed when meeting with any acid, polymerized if contacting with any acidic material or forein substance containing reactive hydrogen, and copolymerization and cross-linking can be also taken place between it and the compound containing two or more than two reactive hydrogens or groups.
MAPO has been used as cross-linking agent and curing agent on the cladding layers of missile resin to heighten the capabilities of elasticity and ballistic in propellant. It works well for the application of AP-based oxidizer in HTPB propellant.
