METHOD OF PRODUCING ACETONITRILE FROM AMMONIA AND COMPOUNDS CONTAINING ACETYL GROUP Russian patent published in 2012 - IPC C07C255/03 C07C253/20 C07C253/22 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing acetonitrile from compounds containing an acetyl group. The method involves contact of compounds from the CH₃COR family, where R denotes CH₃COO (acetic anhydride), CH₃CH₂O (ethyl acetate), ONH₄ (ammonium acetate), or mixtures thereof, containing two or three components listed above, with ammonia gas in a tubular reactor in the presence of catalysts γ-Al₂O₃ or γ-Al₂O₃ with 2-10% H₃PO₄ (wt) at reaction temperature 320-415°C and feeding raw material in amount of 0.3-1.05 kg raw material per litre of the catalyst per hour.

EFFECT: method widens the range of starting material for producing acetonitrile and lowers power consumption during conversion and extraction of the end product.
