Description of the invention (1) Comparison of related applications This application is part of the US Patent Application No. 09/208/053 (filed on December 9, 1998) for a continuation of the patent application. BACKGROUND OF THE INVENTION The present invention relates to a novel method for the ammoxidation of alcohol mixtures to nitrile mixtures. In particular, the present invention relates to increasing the yields of co-products hydrogen cyanide and acetonitrile produced during the amination of propylene to acrylonitrile (preferred ratios). Several patents focus on injecting methanol or ethanol into a fluidized bed reactor to produce hydrogen cyanide or acetonitrile. In addition, these references further reveal that methanol or ethanol can be introduced into the fluidized bed to increase the co-product cyanidation II or acetonitrile 'and simultaneously produce acrylic nitrile. For example, U.S. Patent Nos. 3,911,089; 4,485,079, and 5,288,473 are related to the ammonia oxidation of methanol to produce hydrogen cyanide by injecting the methanol into a fluidized bed containing an ammonia oxidation catalyst suitable for the production of acrylonitrile. Each of these references teaches that methanol injection can be done simultaneously with the preparation of acrylonitrile. In addition, Japanese patent applications 74-87,474; 79-08,655; and 78-35,232 are similar methods for increasing the yield of hydrogen cyanide during the preparation of acetonitrile. Japanese Patent Application No. 2 [1990] -38,333 relates to improving the yield of acetonitrile by injecting acetone and / or ethanol into an ammonia oxidation reactor containing an ammonia oxidation reaction catalyst. The method disclosed in the Japanese patent application involves the simultaneous injection of acetone and / or ethanol into an ammoxidation reactor and the production of acrylonitrile. All of these patents are related to the production of additional hydrogen cyanide or acetonitrile. The present invention relates to a method of adding one or two main common products (ie, HCN and acetonitrile) during the preparation of acrylonitrile and simultaneously (1) saving and increasing common production.

Description of the invention (2) Raw material costs related to product yield and (2) Achieving the desired co-products that are the same as or better than those obtained using net alcohol (such as methanol / ethanol) Conversion rate and selectivity (based on slaves). The relative content of hydrogen cyanide and acetonitrile can be controlled by the method of the present invention. We unexpectedly found that the use of a crude alcohol mixture can achieve the desired increase in the production of acetonitrile and hydrogen cyanide during the production of acrylonitrile. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for greatly increasing the yield of one or more of hydrogen cyanide and acetonitrile, which are co-products produced during the preparation of acrylonitrile from propylene or acrylic acid. An object of the present invention is to provide a method for converting a crude alcohol mixture containing methanol, ethanol, other alcohols, and water into hydrogen cyanide and acetonitrile during the preparation of fufangbu, without substantially affecting the yield of propylene. It is a further object of the present invention to provide a method for converting an alcohol containing ethanol to acetonitrile, which may or may not include methanol. Methanol can be used to adjust the relative amounts of the hydrogen cyanide and acetonitrile co-products produced to a desired content in ethanol. Therefore, as the demand for hydrogen cyanide increases, methanol or additional methanol can be added to the ethanol feed mixture to achieve a promoted content of hydrogen cyanide. In addition, if additional production of acetonitrile is desired relative to hydrogen cyanide, the ethanol content in the alcohol feed can be increased to promote the relative content of acetonitrile produced. The additional objects and advantages of the present invention and the distinguishing features will be shown in the description in part, and will become apparent to those skilled in the art when testing the following, which can be learned by implementing the present invention. The purpose and advantages of the present invention can be adapted to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) by this paper size (please read the precautions on the back before filling this page) -I n I ϋ ϋ I an ϋ. ^ 1 ϋ ϋ 565547 A7 V.
