Tetraaryl borate compound and method for producing same
The present invention relates to a novel tetraaryl borate compound and a method for producing the same, and a method for producing a tetraaryl borate compound using the tetraaryl borate compound as an intermediate. According to the present invention, it is possible to provide a tetraaryl borate compound which has high thermal stability and can be safely handled industrially and a method for producing the same. It is also possible to provide a method for producing a tetraaryl borate compound used as a co-catalyst for a polymerization reaction using a metallocene catalyst by further reacting the tetraaryl borate compound with an amine compound.
1. A method for producing a tetraaryl borate compound of the following formula (5):
wherein R 1 to R 3 each are an alkyl group having 1 to 30 carbon atoms or an aryl group having 6 to 30 carbon atoms, wherein
the tetraaryl borate compound of the following formula (1):
wherein M + is NH 4 + , and an amine compound are reacted, wherein the amine compound is of the following formula (4):
wherein R 1 to R 3 are the same as above.
2. The method for producing the tetraaryl borate compound according to claim 1 , wherein R 1 and R 2 are a methyl group, an octyl group, a decyl group, a dodecyl group, a tetradecyl group, a hexadecyl group, an octadecyl group, an oleyl group, a beef-tallow-alkyl group, or a hardened-beef-tallow alkyl group.
3. The method for producing the tetraaryl borate compound according to claim 1 , wherein R 3 is a methyl group or a phenyl group.
4. The method for producing the tetraaryl borate compound according to claim 2 , wherein R 3 is a methyl group or a phenyl group.
