Description

Technical Field

[0001] The utility model relates to the field of catalysts, in particular to an automatic configuration mechanism for rare earth catalysts. Background Art

[0002] Triisobutyl aluminum is a catalyst for the polyolefin industry, an intermediate for the manufacture of organic compounds, rare earth rubber, and a catalyst for polymer polymerization. Triisobutyl aluminum, a raw material for catalysts used in rubber production, is extremely active and self-ignites when exposed to air. It reacts strongly with water, acid, alcohol, and ammonia and explodes. It can emit strong smoke or catch fire in the air, which can burn the human body. It needs to be diluted to a safe concentration (generally 20 g / L) with solvents such as gasoline. When storing, the container should be dry, isolated from the air, and protected with nitrogen. During the preparation of the catalyst, due to phase changes, the suspension needs to be stirred to promote the chemical reaction. The laboratory preparation of the catalyst requires the hose to be connected to the sealed tube and artificially shaken to promote the reaction. If the hose falls off and the material leaks, it will cause personal injury. There are great safety hazards in the preparation work. Utility Model Content
