This invention relates to a catalyst compound for the metathesis of olefins represented by the formula:
wherein M is a Group 8 metal; X and X
1
are anionic ligands; L is a neutral two electron donor; L
1
is N, O, P, or S, preferably N or O; R is a C
1
to C
30
hydrocarbyl or a C
1
to C
30
substituted hydrocarbyl; G* is selected from the group consisting of hydrogen, a C
1
to C
30
hydrocarbyl, and a C
1
to C
30
substituted hydrocarbyl; R
1
is selected from the group consisting of hydrogen, a C
1
to C
30
hydrocarbyl, and a C
1
to C
30
substituted hydrocarbyl; and G is independently selected from the group consisting of hydrogen, halogen, C
1
to C
30
hydrocarbyls and C
1
to C
30
substituted hydrocarbyls.
This invention also relates to process to make alphaolefins comprising contacting an olefin, such as ethylene, with a feed oil containing a triacylglyceride (typically a fatty acid ester (such as methyl oleate)) with the catalyst compound described above. The fatty acid ester may be a fatty acid methyl ester derived from biodiesel.
本发明涉及一种用于烯烃交换反应的催化剂化合物,其表示为以下化学式:
其中,M是8族金属;X和X1是阴离子配体;L是一个中性的两电子给体;L1是N、O、P或S,优选N或O;R是C1到C30的烃基或C1到C30的取代烃基;G*选自氢、C1到C30的烃基和C1到C30的取代烃基;R1选自氢、C1到C30的烃基和C1到C30的取代烃基;G独立地选自氢、卤素、C1到C30的烃基和C1到C30的取代烃基。
本发明还涉及一种制备α-烯烃的方法,包括将烯烃(如乙烯)与含有三酰甘油(通常是脂肪酸酯(如油酸甲酯))的进料油使用上述催化剂化合物进行接触。脂肪酸酯可以是从生物柴油中得到的脂肪酸甲酯。
