Process for sulfonating halobenzene derivatives with sulfur trioxide |
| 摘要 |
A process for sulfonating at least one halobenzene with sulfur trioxide (SO3) comprising the following steps: Step 1. manufacturing a gaseous mixture [mixture (M)] comprising SO3 and at least one additional gas different from SO3 by oxidizing sulfur dioxide in the presence of at least one catalyst, wherein the SO3 content in mixture (M) is from 1 to 95% by volume, relative to the total volume of mixture (M); and step 2 contacting said mixture (M) with said at least one halobenzene. |

1. A process for sulfonating at least one monohalobenzene with sulfur trioxide (SO3) comprising the following steps—:
Step 1. manufacturing a gaseous mixture (M) comprising SO3 and at least one additional gas different from SO3, by oxidizing sulfur dioxide (SO2) in the presence of at least one catalyst, wherein the SO3 content in the mixture (M) is from 1 to 95% by volume, relative to a total volume of the mixture (M)—; and Step 2. contacting the mixture (M) with the at least one monohalobenzene. |
