The present study deals with the synthesis of octylamines by ammonia alkylation with octanol-1 in gaseous phase using solid microporous materials as AlPO-11, SnAPO-11, SAPO-31 and SAPO-41. They were prepared by hydrothermal process in Teflon steel less reactor under autogenic pressure and at determined temperatures. SAPO-31 material was obtained using HF acid and without fluoride media. The materials have presented a catalytic activity in the study reaction. Primary isomers (MOA) were obtained with better selectivity of about 85 to 99%. Silicium and tin are the origin of the acidity and are responsible to the activity catalytic of SnAPO-11 and SAPO-31 materials.
