| Abstract: | The technological process for manufacturing fatty acid nitriles by catalytic ammoniation and dehydration from glycerides and the influence of the amount of catalyst,ammonia flowrate,reacting temperature,temperature and packings of fractional column on reacting activity were investigated. The results indicated that the yield of nitriles is about 92% under the following conditions; amount of catalyst, 3% ~5% ; ammonia flowrate, 800L/ h. kg; final reacting temperation, 270C;temperature of fractional column, 80-86C ; packings of fractional column, dehydrating substance. |
