GV is the name for a Soviet nerve agent, which is structurally similar to the nerve agent soman. From the U.S. Department of Defense and NATO combat this substance was given the designation GV (G for Germany, V for engl viscous " tough, viscous .").
Isomerism
GV has a chiral center at the phosphorus atom, so there are two enantiomers, one has (R ) configuration, and the other is - configured (S). The preparation processes described provide the racemic GV, which is a 1:1 mixture of ( R) - ( dimethylamido ) fluorophosphoric acid -2-N ', N'- (dimethylaminoethyl ) ester and (S ) - ( dimethylamido ) fluorophosphoric acid -2-N ', N'- (dimethylaminoethyl ) ester.
Protection measures
GV acts already lethal in small quantities. Attack surface is the entire body. Therefore, only a full-body protective clothing and a protective mask provide sufficient protection. Before a fight substance use oxime tablets can be taken. In a GM poisoning helps - in contrast to many other nerve agents - an injection of atropine ( the venom of the deadly nightshade ) not. During the weeks of treatment you try to regenerate with obidoxime acetylcholinesterase.
For decontamination can be used oxidizing agent, and alkaline solutions, as the hydrolysis of nerve agents is accelerated in a basic medium. Have proven useful also for bleaching powder and sodium carbonate solutions resistant surfaces for delicate items.
