PROCESS FOR THE PRODUCTION OF ACROLEIN AND/OR ACRYLIC ACID |
摘要 |
<p>In industrial scale production of acrolen and/or acrylic acid by catalytic gas-phase oxidation of propylene or a propylene-containing gas with molecular oxygen or a molecular oxygen-containing gas or in industrial scale production of acrylic acid by catalytic gas-phase oxidation of acrolein or an acrolein-containing gas with molecular oxygen or a molecular oxygen-containing gas, this invention provides a process characterized in that the initial stage operation is carried out under advancedly elevated reaction temperature and thereafter the reaction temperature is lowered to carry out the steady state operation. According to this process, acrolein and/or acrylic acid can be produced in high yield stably over prolonged period.</p> |
