Firstly I would like Drs. Frederic Denonne and Ian Newington who gave the
answers to my question. Here they are. Hopefully they are useful for some
one.

Yantao,
As BF3.OEt2 is moisture sensitive, if it isn't dry it is probably not
BF3.OEt2. You can also distill under reduced pressure (bp 67degC/43mmHg)
from CaH2 to purify.
