@@elnombre91 The smell is not easily described, but it is by far the worst I have encountered. I wouldn't say it necessarily smells like rotting flesh, although it is reminiscent of that. It smells more like what you would expect a chlorine compound and hydrogen sulfide to smell like. For the most part, however, you do not come into contact with it during this synthesis since it must not contact the air.

Great! I love this kind of reaction (and I love reactions with sulfur in general). I would have added another distillation just for good measure (maybe fractional, although allowing it to reach the top of the coloumn would have required a ton of heat), but you know the boiling point of the stuff that came over and I guess that it was reasonably pure.

May I submit a proposal for the preparation of Thionylchloride? I found a hint, that it should be possible to prepare SOCl2 in lab- scale out of Sulfurdichloride and Sulfurtrioxyde according SO3 + SCl2 -> SOCl2 + SO2. Thionylchloride is known to be a useful chlorinating agent and may replace the phosphorous-clorine compounds in many cases (PCl3, PCl5 and POCl3), which are very hard to obtain, due to their "dual-use" characteristics.

Very nice work! After the chlorination was finished you're still left with a chlorine generator setup filled with chlorine gas. How did you clean that one up without exposing yourself to chlorine gas? I used a two-neck RBF as the generator flask, and when things were finished, through the free neck I'd connect an aquarium air pump and blow the excess chlorine out into a beaker of aq. NaOH..

Ever thought about going a step further with this and making sulfur tetrachloride? It only exists at low temps (like dry ice acetone bath theps), but it does exist and seems like interesting stuff! It hydrolyses to thionyl chloride and I'd be really interested in seeing what it does to an anhydrous carboxylic acid. Maybe make an acid anhydride and thionyl chloride, which then reacts with another acid to make an acid chloride? Nothing like making two usefull things at the same time lol!

@@DougsLab You could dehydrate sodium bisulfate to sodium pyrosulfate, and then on heating it would yield sodium sulfate and sulfur trioxide gas. According to wikipedia you should then be able to get thionyl chloride by bubbling that through sulfur dichloride. What complications are you running into? Here's a preparation from a cookbook I have: Flask A of the apparatus in Fig. 166 is charged with pure 65% oleum, flask B with 100 g. of SC12 (see p. 370). Flasks is slowly heated in an H2SO4 bath, while B is cooled with an ice-water bath. The stoichiometric quantity of SO3 is thus gradually distilled onto the SCl2. The reaction proceeds with SO2 evolution (use a hood!). Partial solidification of the flask contents frequently occurs at the beginning. However, the contents should again be completely liquid when the addition is completed. If necessary, the flask is heated at the end for a short time on a water bath. Flask A is then disconnected, the ground joint at Q is stoppered, and the mixture is slowly distilled through a column (use a hood!). The mixture must be protected from contact with atmospheric moisture. The middle fraction is further purified by repeated careful fractionation, with S added to the distillation charge in order to convert all sulfur chlorides present to S2Cl2. The contents are distilled through an efficient column until a completely colorless product, coming over at 76-77°C, is obtained. The yield is about 80% of theoretical.

@erwinrommel95095 жыл бұрын
The Cl2 is getting used up so if the rate of Cl2 production is low enough it should all get taken up by the S without any excess getting past the reaction flask Also at 8:52 of the video you can see a line attached to the vacuum adaptor which likely leads to the back of the fund hood for any excess Cl2 to vent.

convert S2Cl2 o SCl2, react the dichloride with SO2 and Cl2 and you get SOCl2, which is a very useful reagent (acyl chlorides, alkyl halides, alkyl sulfites and other interesting things can be obtained from it; unlike phosphorus chlorides, it is a much cheaper chlorinating agent, albeit more volatile and toxic)
