High-temperature resistant sulfonated aromatic polyether ketone cation exchangers and sulfonated poly (phenylene sulfide) cation exchangers as catalysts at reaction temperature above 150° C |
摘要 |
High-temperature resistant sulfonated aromatic polyether ketone cation exchangers and sulfonated poly(phenylene sulfide) cation exchangers are revealed as catalysts for various reactions at reaction temperatures above 150° C.The invention relates to the use of sulfonated aromatic polyether ketone cation exchangers and sulfonated poly(phenylene sulfide) cation exchangers as catalysts for such reactions. The preferred reaction is esterification to make octyl palmitate.
