Used 12,000 TPY AKD Wax Plant. Fatty Acid Chloride, Triethylamine and Toluene are subject to a batch reaction in a glass lined vessel at 65Â°C. The corresponding ketene and then the diketene (AKD wax) are formed. The reaction mass is decanted and then extracted. The extract is then steam vacuum distilled. This is a fine tuned totally recovering process. Toluene as well as unreacted triethylamine are recovered in the work up and reintroduced in the next batch. The process is automated (ABB).
