“…Several research group have studied the dehydration of 2,3-BDO to 1,3-BD or MEK using various catalysts since the 1940s. − Most research was focused on developing dehydration catalysts or reaction conditions that show good performance. Recently, the reaction kinetics of the dehydration of 2,3-BDO to 1,3-BD and MEK was defined over an amorphous calcium phosphate (a-CP) catalyst and a kinetic model proposed to explain the dehydration reaction of 2,3-BDO to 1,3-BD and MEK using an a-CP catalyst .…”

A deactivation model for the dehydration of 2,3-butanediol (2,3-BDO) to 1,3-butadiene (1,3-BD) and methyl ethyl ketone (MEK) on an amorphous calcium phosphate (a-CP) catalyst is herein proposed. The deactivation of a-CP catalyst can be explained by the following steps: (i) 1,3-BD selectivity is increased sharply as the temperature increases; (ii) the high 1,3-BD selectivity and temperature raise a possibility of the polymerization of 1,3-BD; and (iii) heavy compounds made by polymerization cover the active surface of the catalyst and block the pores of the catalyst. Deactivation data for around 86 h obtained from a laboratory-scale fixed-bed reactor operated under isothermal conditions were found to be modeled well using the simplified concentration-independent generalized power law expression of the form dα/dt = −K d(α – αeq) m . The values of deactivation order m, the limiting activity at infinite time αeq, and the activation energy for deactivation E d are found to be 1.32, 0.33, and 1.00 × 1006 J/mol, respectively. Also, it was confirmed that the activity of a-CP catalyst is constant after the regeneration through the same experiment conducted with the regenerated a-CP catalyst.

An In‐Situ Self‐regeneration Catalyst for the Production of Renewable Penta‐1,3‐diene

Catalyst deactivation is a problem of great concern for many heterogeneous reactions. Here, an urchin‐like LaPO4 catalyst was easily developed for pentane‐2,3‐diol dehydration; it has an impressive ability to restore the activity in situ by itself during the reaction, accounting for its high stability. This facilitates the efficient production of renewable penta‐1,3‐diene from pentane‐2,3‐dione via a novel approach, where penta‐2,3‐diol was obtained as an intermediate in 95 % yield under mild conditions.
