want to know one reduction reaction in detail

[nikhil108]

hi friends,

 

i need your help in chemical reaction,making boron trichloride but one very toxic byproduct gas is created hence

 

want to take all precautions

 

When Arsenic trichloride is reacted with Sodium Borohydride it is reduced to Arsine gas and Boron trichloride.

 

my question is,

 

1.Does any catalyst needed for this reacion?

 

2.Does this reduction do not need heating?

 

3.Arsenic Trichloride is liquid at RM,is this reaction is spontaneous?

 

I searched many books but havent found answers to above.
