Boiling point: 86 ℃ (10 mmHg)

Refractive index \ (d_D ^ {20} \): 1.4494

Solubility: soluble in alkanes and aromatic hydrocarbons; Strictly prohibit contact with water, alcohol, and air

Core hazard characteristics: Exposure to air can cause smoke and spontaneous combustion; Reacts violently with water, releases flammable isobutane, and poses a risk of explosion; The entire process must be stored and transported under nitrogen sealed protection.

- Organic aluminum co catalyst;

- The high steric hindrance and excellent controllability of the polymerization process are conducive to the preparation of high cis structured polydienes;

- Highly active organic metal alkyl aluminum, which can also be used as a selective reducing agent for organic synthesis;

- In industry, there are two circulation specifications: pure liquid and diluted solution of hexane/toluene.

Main applications 

- Synthetic rubber industry (maximum use)

Directional polymerization co catalyst for butadiene rubber (BR) and isoprene rubber (IR); Adjust the cis content and molecular weight distribution of polymers.

- Polyolefin industry 

Components of polyethylene and polypropylene olefin polymerization catalytic system; Metallocene catalytic system co catalyst.

- Fine chemical industry field

Organic synthesis selective reducing agent; Metal aluminum thin film CVD deposition precursor; Organic metal synthesis intermediates. 

Storage and packaging

Stainless steel pressure resistant steel drums, nitrogen sealed filling
