1) metathesis
[英][mɪ'tæθɪsɪs] [美][mə'tæθəsɪs]
易位反应
1.
It is concluded that the active centers adsorbed with formaldehyde is favorable for metathesis and dimerization rather than polymerization,while,the dehydroxylation or fluorination of silica support surface facilitates the transformation from metathesis into polyme
通过计算发现,甲醛的吸附有利于易位反应和二聚反应,不利于向乙烯聚合反应的转化,但是催化剂载体表面脱羟基或者氟改性对这种转化有非常有利的影响。
2) metathesis ring-openning polymerization
易位开环聚合反应
3) Ring closing enyne metathesis
烯炔闭环易位反应
4) response facilitation
反应易化
5) in-situ reaction
