- I call it VVX it’s about 5/6 as toxic as VX since it contains VC and other V-series contaminants but it has a much higher vaporization pressure so it is more easily aerosoled and it is extremely persistent which makes it good for area denial.
- VX is O-Ethyl S-(2-diisopropylaminoethyl) methylphosphonothioate
- VVX is O-Ethyl S-(2-dimethylaminoethyl) methylphosphonothioate.
- into a very dry 2000 ml round bottom flask, the following ingredients are added, quickly, one after the other with swirling to mix them a few boiling chips, 800 ml anhydrous ethyl ether, 284 grams of methyl ethoxyphosphoryl chloride, 212 grams of dimethylaminoethanethiol, and 212 grams of triethylamine. it is very important that the glassware be very dry, and that the ingredients espescially the methyl ethoxyphosphoryl chloride be protected from moisture, because the presence of water really lowers the yield in this this reaction.
- when the ingredients have been added and mixed, a good efficient condenser topped with a drying tube is attached to the flask and a flow of very cold water is put trought the condenser .
- the contents of the flask are heated to boiling with a hot water bath and the reflux is maintened for one hour.
- the byproduct of this reaction, hydrogen chloride, is absorbed by the tiethylamine as it is produced, forming triethylamine hydrochloride cristal cristal
- at the end of the eating period, the mixture is cooled and the cristal of triethylamine hydrochloride are filtred out in a Buchner funnel.
- the filtered reaction mixture is then returned to 2000 ml round bottom flask, a few boiling chips added, the glassware set up for simple distillation and the ether removed by distilling it of under a gentle vacuum.an aspirator is perfect for this job since it will flush the ether fumes down the drain.
- when most of the ether is gone, the mixture is poured into a 1000 ml round bottom flask with a few boiling chips. the remnants in the 2000 ml flask can be rinsed out with ether an poured into the 1000 ml flask. once again this flask is set up for a simple distillation and full aspirator is applied to it. the last of the triethylamine and ether (bp 88 C°) will be gone shortly.
- now a vacuum from a good quality vacuum pump is applied to the distillation. A vacuum of less 1 mmHg is to be preferred here to keep the distillation temperatures reasonable and to avoid burning product. BE CAREFUL THE PUMP MUST NOT BE STOPPED DURING THE DISTILLATION. IF THE PUMP STOPS, RUN OUT AND NEVER COME BACK !!!
- after a small forerun is collected in a 250 ml flask, a 500 ml flask is attached and the main bulk of the product is collected at a boiling point of 80 C° at a vacuum of 0.6 mmHg.
- the yield is 260 to 275 ml of product. a fair amount of tar remains in the distilling flask.
- you have now VVX agent. NOTE THAT UNLIKE VX THIS IS NOT A BINARY IT'S FUMES ARE LETHAL UPON COMPLETION OF THE RUN IN PARTS PER BILLION AND UNLESS DEACTIVATED WITH CHLORINE OR OXIDIZED IN THE OPEN AIR WILL REMAIN SO INDEFINITELY
