Remarks:
Component A is detailed in US Patent 5777143 For more information about aluminum oxide, please refer to the technical announcement titled Akzo Nobel Company's Aluminum Oxide Characteristics. Isopar E is a mixture mainly composed of C8 fatty hydrocarbons produced by ExxonMobil. The data is for Isopar E solution with a content of 7% aluminum. C is calculated from gas chromatography analysis of hydrocarbons, while hydrogen is obtained from hydrolysis. D is obtained by titration of hydrolysis products. E is determined by 31P nuclear magnetic resonance method.
application
The Isopar E solution of MMAO-7 serves as a co catalyst in the single reaction point polymerization process of olefins or other monomers.
storage
The Isopar E solution of MMAO-7 is stable under dry inert gas protection and away from heat sources. The storage stability of Isopar E solution of MMAO-7 is significantly improved compared to traditional methylaluminoxane, but long-term storage at a temperature of 25 ° C or above may cause the solution to become viscous.
Packaging and transportation
Isopar E solution of MMAO-7 can be obtained worldwide in mobile tank packaging. Only in North America can Isopar E solutions of MMAO-7 be obtained for truck and train tanker packaging. The packaging can is made of carbon steel and equipped with bottom insertion pipes for top unloading, with all connections located in the steam space section. Packaging and transportation comply with international regulations.
Security and Handling
The Isopar E solution of MMAO-7 can burn in air and react violently with water. The Isopar E solution solution of MMAO-7 must be stored under dry inert gas protection, such as nitrogen or argon gas. Before coming into contact with alkyl metals, water in the production process must be carefully removed. Otherwise, it may cause an explosion. MMAO-7 solution may ignite upon contact with air or water. The products of complete combustion of the Isopar E solution of MMAO-7 are alumina, carbon dioxide, and water. Isopar E solution of MMAO-7 can cause severe skin and eyewear burns.
When using MMAO-7, it is mandatory to wear appropriate personal protective equipment. For detailed information on the safe storage, use, and operation of Isopar E solution for MMAO-7, please refer to the Safety Data Sheet (SDS). Before accepting this product, carefully read the relevant safety information on SDS. SDS can be obtained from the following sources:
