surface area 19 m 2 g was treated in a fluidized bed reactor at 180 u00b0 c for 30 minutes in a 50 50 by volume hydrogen nitrogen atmosphere it was cooled to room temperature in a 100 n 2 atmosphere a sample was transferred to a glass ampul and 2 weight 2 vinylpyridine a liquid based on the weight of the clay was introduced into the ampul atmosphere the ampul was flushed with nitrogen to remove any traces of oxygen and sealed it was placed in an oven at 170 u00b0 c and reacted for 30 minutes at the end of the 30 minutes reaction time the ampul was removed from the oven and cooled to room temperature the ampul was opened the clay removed and split into 2 samples one sample was water washed the other was acetone ether washed the resulting washed products contained 0 82 2 vinylpyridine as determined by carbon and nitrogen analysis an air classified kaolin clay as described in example vii was treated in a fluidized bed reactor in 50 50 by volume n 2 h 2 atmosphere for 5 minutes at 305 u00b0 c the clay was cooled in n 2 to 178 u00b0 c and acetylene gas was then passed through the clay for 5 minutes the clay was further cooled to room temperature in a n 2 atmosphere the treated sample was analyzed by carbon species the resulting clay.
