Isobutylene autopolymerization
Thread Content
The dimer in isobutylene products is required to be within 10 ppm, and the device produces qualified products. However, sometimes due to market reasons, when isobutylene is stored for a long time, self-polymerization occurs in the tank, especially in summer when the temperature is high.； How to solve this problem?
I have just learned this issue* Yes, I am engaged in MTBE cracking technology. I have communicated with foreigners before that imported olefins generally add 50-100ppm polymerization inhibitor. ； This problem really occurred in the isobutylene storage tank installed by the poster's company. Polymerization inhibitors are one way to go, but we need to communicate well with downstream customers to avoid causing problems for customers.
