The results were as follows:Afterthe NH_4Y zeolite was dealuminated with Oxalic acid,the conversion of pinenespeeded up markedly, but the selectivity of camphene also dropped downmarkedly.After the NH_4Y zeolite was infused in solution of Mg(NO_3)_2,Zn(NO_3)_2 or Al(NO_3)_3 to remove corresponding oxide,the conversion rate of pinenedropped down,and the selectivity of camphene had little increase.
