Definitions
- the invention relates to a process for the production of purified sulfuryl fluoride from sulfuryl fluoride which is contaminated with sulfur dioxide.
- Sulfuryl fluoride is a fumigant, for example for use in museums. It can be made from sulfur dioxide, chlorine and hydrogen fluoride over catalysts. Due to the manufacturing process, also in other manufacturing processes, or application-related, sulfur dioxide can be present as an impurity. It is desirable if the sulfur dioxide is separated from the sulfuryl fluoride contaminated therewith.
- U.S. Patent 4,950,464 teaches that thionyl fluoride, acidic ingredients, water and "certain other contaminants" can be separated with activated alumina.
- Activated carbon the so-called US patent, can be used to separate sulfur dioxide, hydrogen fluoride, chlorinated hydrocarbons and certain other contaminants.
- the adsorbents can also be used in series.
- the object of the present invention is to provide a method with which the purification of sulfuryl fluoride which contains sulfur dioxide is simplified.
- BESTATIGUNGSKOPIE The process according to the invention for producing purified sulfuryl fluoride from sulfuryl fluoride which is contaminated with sulfur dioxide provides that the sulfuryl fluoride contaminated with sulfur dioxide is contacted with aluminum oxide in an adsorption stage in order to separate sulfur dioxide.
- Activated aluminum oxide is preferably used.
- the aluminum oxide can be used in any form, for example as granules or as a powder. It serves to adsorb the sulfur dioxide. Other contaminants such as thionyl fluoride, acidic components, water and sulfuryl chloride fluoride, if any, are also adsorbed. Activated carbon is not necessary, especially not if it does not contain chlorinated hydrocarbons. Activated carbon is therefore preferably not used, and the use of a single type of adsorbent is of course advantageous in terms of process technology.
- the cleaning according to the invention using an aluminum oxide adsorption stage can of course be combined with conventional cleaning measures such as contacting with cleaning solutions, for example with water, weakly alkaline solutions, in particular weakly alkaline aqueous solutions, or with an oxidative wash, for example with an aqueous hydrogen peroxide solution.
- the sulfuryl fluoride is first contacted with an oxidative wash, preferably an aqueous hydrogen peroxide solution.
- the sulfuryl fluoride pretreated in this way is then passed through one or more aluminum oxide adsorbent stages.
- the contacting of the sulfuryl fluoride with aluminum oxide is usually carried out in a temperature range from -30 ° C. to +100 ° C., preferably ambient temperature, and a pressure in the range from 0 to 20 bar, preferably at ambient pressure, in particular in the gas phase.
- the process according to the invention has the advantage that only one type of adsorbent, namely aluminum oxide, has to be used. Sulfur dioxide and other contaminants such as sulfuryl chloride fluoride can be reliably separated.
- Compalox ® ( ⁇ N / V-850) used is a commercial product from Martinswerk GmbH, Bergheim, Germany. It is an active, granular aluminum oxide.
- Pore volume 0.35 cm 3 / g specific surface: 200 - 260 m 2 / g
- Compalox ® 200 ml of Compalox ® were filled into a glass tube with a content of 250 ml. Through the filled glass tube at 20 ° C and 1 bar abs. Passed through 380 g of sulfuryl fluoride (SF) containing 250 ppm S0. The contact time was 3 seconds. After the Compalox ® passage, an S0 2 - Content of 100 ppm found. (Analysis method: GC and Dräger measuring tube S0 2 ).
- SF sulfuryl fluoride
- Example 1 Experimental setup, experimental procedure, analysis and amounts used as in Example 1.
- the S0 2 content had previously been reduced in an H 2 0 2 washer from 250 ppm to 50 ppm.
- Compalox ® 85 kg were filled into a steel tube with a content of 100 l. Through the filled steel tube at 20 ° C and 1 bar abs. Passed 418 kg of sulfuryl fluoride (SF) containing 25 ppm S0 2 . The contact time was 20 seconds. After the Compalox ® passage, an S0 2 content of 10 ppm was found. (Analysis method: GC and Dräger measuring tube S0 2 ).
- Example 3 By the already used in Example 3 were Compalox ® under the same physical conditions SF additional 527 kg with a S0 2 content of 10 to 15 ppm passed. Since the SF used came from an ongoing SF process, different samples were taken at the beginning and as the production campaign progressed. After the Compalox ® passage, S0 2 contents between 2 and 8 ppm were found. (Analysis method: GC and Dräger measuring tube S0 2 ).
