Properties

Solubility: This substance is insoluble in water, but soluble in organic solvents such as hydrocarbons and aromatics.

Stability: Reacts with water, is sensitive to heat and moisture, hydrolyzes slowly in humid air, and needs to be moisture-proof and sealed. It is flammable, toxic and non-corrosive.

Reactivity: As an external electron donor, it improves the activity, stereospecificity and service life of propylene polymerization catalysts.

Applications

1. Polymer synthesis: As an efficient external electron donor, it is used to synthesize high-performance polymers such as syndiotactic polypropylene.

2. Coating additives: It can be used as a weathering agent in coatings and paints to improve their durability and corrosion resistance.

3. Organic synthesis: It can be used as a silicon control reagent to initiate or promote chemical reactions.
