Title : Gamma hydroxybutyrate ( GHB ) , gamma butyrolactone ( GBL ) and 1 , 4 butanediol ( 1 , 4 - BD ; BDO ) : A literature review

Misuse of gamma hydroxybutrate (GHB) and gamma butyrolactone (GBL) has increased greatly since the early 1990s, being implicated in a rising number of deaths. This paper reviews knowledge on GHB and derivatives, and explores the largest series of deaths associated with their non-medical use. Descriptive analyses of cases associated with GHB/GBL and 1,4 butanediol (1,4-BD) use extracted from the...

Dielectric and Thermodynamic Properties of 2, 3-Butanediol + 2-ethyl-1-hexanol Mixtures

Experimental results of dielectric investigations for binary mixtures of 2, 3-butanediol, 2, 3-BD, in2-ethyl-1-hexanol, 2EH, were reported for various mole fractions and temperatures (298.2-308.2) Kand they were used to calculate dielectric parameters such as Kirkwood correlation factor, excesspermittivity and Bruggeman parameter. These parameters were used to carry out temperaturedependent die...

Microbial Production of Optically Active 1,3-Butanediol from 4-Hydroxy-2-butanone.

synthesizing various optically active compounds such as azetidinone derivatives, which are intermediate materials for penem and carbapenern antibfotics,i'2) pheromones,3) fragrances,4'S} and insecticides.6) Although microbial asymmetric processes for optically aetive 1,3-BDO have been reported,T'S) the product{vity was not satisfactory, and they produced only (R)-(-)-1,3-BDO. Thus, we started a...

Volumetric properties of {n-butyl acetate + 1-butanol + 1,2- butanediol} at temperature between [298.15 ,303.15 and 308.15] K.

Densities and excess molar volume of the binary and ternary mixtures formed by nbutylacetate+ 1-butanol + 1,2-butanediol were measured at (298.15, 303.15, and 308.15) K forthe liquid region and at ambient pressure (81.5) k Pa , for the whole composition range. Theexcess molar volumes,VmE and excess partial molar volume ViE ,were calculated fromexperimental densities.The excess molar volumes are...
