摘要
This invention is concerned with improved boron phosphate dehydration catalysts. More specifically, this invention is directed to a process for the conversion of an aldehyde to a diolefin comprising contacting an aldehyde of 4 to 6 carbon atoms in the vapor phase with a catalyst comprising boron phosphate wherein the boron phosphate has been treated with an ammonium carbonate or bicarbonate salt prior to calcination. This invention is also concerned with a large port catalyst for dehydration reactions wherein the improvement comprises the use of a catalyst with a molar ratio of P/B of about 1.0 modified with from 0.1 to 10 mole percent, based on moles of boron, of a carbonate salt selected from (NH4)2CO3 and NH4HCO3.
