In what way is GBL cleaner created?
GBL extracts were discovered in unadulterated wine samples to create GBL cleaner. This discovery implies that GBL occurs naturally in some wines and can be found in comparable products.
The detection concentration was approximately 5 g/mL, and the analysis was easily followed by a GC/MS analysis using a simple removal technique. Although you can find GBL in cheese flavors, the finished product contains only 0.0002% GBL.
In the absence of a copper catalyst, 1,4-butanediol is dehydrogenated at 180-300 ° C and atmospheric pressure to produce -butyrolactone GBL cleaner.
This procedure has a 95 percent return on investment. The liquid-gas phase is extracted during cleaning.
In the laboratory, tetrahydrofuran can also be oxidized with aqueous sodium bromate.
