65 ± 10) % of γ-butyrolactone
A new process for the production of gamma-Butyrolactone is described.
The present invention obtains high yields of α-methylene-η-butyrolactone by heating η-butyrolactone and formaldehyde in the presence of a base.
By treating the thus obtained 5-alkyl-Ϝ-butyrolactone with the carbonate as described above, 5-alkyl-Ϝ-butyrolactone with lessened odor can be obtained.
A new process for the production of gamma-butyrolactone is described.
Gamma-Butyrolactone (GBL) is used as an industrial solvent.
Gamma-Butyrolactone (γ-butyrolactone or GBL) is a hygroscopic colorless oily liquid with a weak characteristic odor and is soluble in water.
You can dilute Gamma-Butyrolactone with a ratio of at most 1/5.
Gamma-Butyrolactone (γ-butyrolactone or GBL) is a hygroscopic colorless liquid with a weak characteristic odor which is soluble in water.
Gamma-Butyrolactone (γ-butyrolactone or GBL) is a hygroscopic colorless liquid with a weak characteristic odor which is soluble in water.
Where does the Gamma-Butyrolactone come from which you sell?
The chiral 3,4-dihydroxybutanoic acid can be further converted to 3-hydroxy-η-butyrolactone by acidification.
The gamma-butyrolactone content in the raw material 1, 4-BG is 1-100 ppm by mass.
gamma-Butyrolactone (γ-butyrolactone or GBL) is a hygroscopic colorless oily liquid with a weak characteristic odor and is soluble in water.
Gamma-Butyrolactone (GBL) is used as an industrial solvent.
The emulsion composition is also characterized in that the weight ratio between 1,3-dimethyl-2-imidazolidinone and γ-butyrolactone, namely (1,3-dimethyl-2-imidazolidinone):(γ-butyrolactone) is within the range from 1:0.03 to 1:2.
In addition, this production method is applied to a novel β-(meth)acryloyloxy-γ-butyrolactone compound.
Delirium in the course of dependence upon gamma-butyrolactone (GBL) - a case report
Disclosed is a process for the production of optically pure (S)-beta-hydroxy-gamma-butyrolactone through the hydrogenation of substituted carboxylic acid derivatives.
A process is described for the production of butane-1,4-diol, η-butyrolactone and/or tetrahydrofuran.
