Selective cracking reactions by cofeeding organic amine or ammonia
摘要:
An improved process for selective cracking of 1,4-disubstituted aromatic compounds whereby the yield of recyclable olefin cracking product is increased. The process is carried out in the presence of a specified type of crystalline zeolite cracking catalyst (e.g. ZSM-5) and the reactor feed is admixed with ammonia or an organic amine.
