Multiple use of benzoin as an aid in neurosurgical practice: the watertight benzoin dressing.
The author presents a survey of his experience with the use of benzoin as an aid to prevent and to treat wound complications as: CSF leakage ruptured meningoceles, prevention of leakage and wound infections, during the use of external cranial drainage, indwelling catheters or implanted cannulas and electrodes. A few other handy uses are also mentioned.
متن کاملBenzoin Type Photoinitiator for Free Radical Polymerization
Benzoin, a popular photoinitiator for free radical polymerization of vinyl monomers, was improved by introduction of two methyl thioether substituents. This new benzoin derivative showed an about 50 times higher light absorption in the near-UV spectral region and performed better than the unsubstituted benzoin in polymerization experiments in bulk solutions or films of acrylate monomers when lo...
متن کاملOxidation of benzoin catalyzed by oxovanadium(IV) schiff base complexes
BACKGROUND The oxidative transformation of benzoin to benzil has been accomplished by the use of a wide variety of reagents or catalysts and different reaction procedures. The conventional oxidizing agents yielded mainly benzaldehyde or/and benzoic acid and only a trace amount of benzil. The limits of practical utilization of these reagents involves the use of stoichiometric amounts of corrosiv...
متن کاملFacile approach to preparing microporous organic polymers through benzoin condensation.
A series of microporous organic networks linked by α-hydroxyl ketone were synthesized based on benzoin self-condensation of multiformyl-containing building blocks. Fourier transform infrared and solid-state (13)C CP/MAS NMR spectroscopy were utilized to confirm the α-hydroxyl ketone linkage of the obtained polymers. The hollow microspheric morphology can be observed from scanning electron micro...
متن کاملBenzoin Radicals as Reducing Agent for Synthesizing Ultrathin Copper Nanowires.
In this work, we report a new, general synthetic approach that uses heat driven benzoin radicals to grow ultrathin copper nanowires with tunable diameters. This is the first time carbon organic radicals have been used as a reducing agent in metal nanowire synthesis. In-situ temperature dependent electron paramagnetic resonance (EPR) spectroscopic studies show that the active reducing agent is t...
