Pilot-plant testing of a catalyst for the synthesis of ethyl acetate from ethanol

Abstract
Owing to its low toxicity, ethyl acetate is a marketable solvent for food and medical industries. A conventional method of ethyl acetate synthesis is etherification of acetic acid by ethanol in the presence of sulfuric acid or cationites. An alternative advanced method for the production of ethyl acetate is dehydrogenation of ethanol on a heterogeneous catalyst; this process can be implemented as its classical variant or in a combination with rectification. For any variant of the process implementation, it is important to test the heterogeneous catalyst for long stable operation. The paper is devoted to testing of commercial catalyst NTK-4 in the long-term operation on a pilot plant. The catalyst demonstrated stable operation with no loss in activity for 1250 hours. Characteristics of the process and compositions of the reaction mixture upon variation of the operation mode are reported.
