Method for producing phthalic anhydride |
| abstract |
The present invention relates to an apparatus comprising two or more reaction zones cooled with a coolant, and one or several devices arranged between the reaction zones and used for intermediate cooling of the reaction mixture between reaction zones, wherein o-xylol and / or A method for producing phthalic anhydride by catalytic partial oxidation of naphthalin using an oxygen containing gas. The temperature of the coolant when introduced into the second or additional reaction zone is lower than the temperature of the coolant when introduced into the first reaction zone and the temperature of the coolant when introduced into the first reaction zone is equal to the second or additional reaction zone. It is characterized in that 20 ° or more higher than the temperature of the coolant when introduced into. |
