The detection limits for GHB and GBL in drinks were found to be always below 0.5 g L1, which is sufficient to identify them in beverages (a dose of about 2 g L1 is commonly used). 8 mg L1 GHB were detectable in urine, which suffices to identify an intoxicated individual. Overall, ...
quinhydrone electrodeThe application of hydroquinone for the coulometric generation of hydrogen ions in propylene carbonate (PC) and g-butyrolactone (GBL) is described. The current-potential curves recorded for theid sepolarizer, titrated bases, indicator and the solvents used showed that the ...
In the present work, (+)-(2 R ,3 R )-1,1,4,4-tetraphenylbutane-1,2,3,4-tetraol (TETROL) was assessed for its host ability in γ-butyrolactone (GBL), 2-pyrrolidone (NP), N -methyl-2-pyrrolidone (NMP), N -ethyl-2-pyrrolidone (NEP), and mixtures of these. These compounds ...
