Benzyl alcohol photodegradation

Jang and McDow (1997) studied the photodegradation of benzo[a]anthracene in the presence of three common constituents of atmospheric aerosols reported to accelerate benzo [a] anthracene, namely 9,10-anthroquinone, 9-xanthone, and vanillin. The photo-degradation experiments were conducted using a photochemical reactor equipped with a 450-W medium pressure mercury arc lamp and a water bath to maintain the solution temperature at 16 °C. The concentration of benzo [a] anthracene and co-solutes was 10" M. Irradiation experiments were conducted in toluene, benzene, and benzene-c/e- Products identified by GC/MS, FTIR, and NMR included benzo[a]an-thracene-7,12-dione, phthalic acid, phthalic anhydride, 1,2-benzenedicarboxaldehyde, naphtha-lene-2,3-dicarboxylic acid/anhydride, 7,12-dihydrobenzo[a]anthracene, 10-benzyl-10-hydroan-thracen-9-one, benzyl alcohol, and 1,2-diphenylethanol. 

Haloperidol A concentrated solution of haloperidol (5 mg/mL) is incompatible with heparin sodium (in sodium chloride or glucose solutions), sodium nitroprusside (in glucose solutions), cefmetazole sodium, diphenhydramine, and sargramostim. Solutions of haloperidol precipitate if diluted with a 0.9% sodium chloride solution.158,159 Photodegradation of haloperidol could be prevented using benzyl alcohol and vanillin.160... 

As expected, no photodegradation of benzyl alcohol or phenol was observed in oxygenafed solution under irradiation but without catalyst. In the presence of cafalysf buf without irradiation no oxidation of benzyl alcohol or phenol was defecfed but a small adsorption of benzyl alcohol was measured while for phenol it was negligible. 

Using a sol-gel approach, a solution-based synthesis of nanocrystalline InNb04 has been reported for the first time. Indium acetylacetonate and niobium chloride, in the presence of benzyl alcohol, are used as precursors which react to yield the desired nanoparticles at 200 °C after 24 hr. These nanoparticles have been shown to have enhanced photocatalytic activity compared to the corresponding bulk materials, when the photodegradation of the dye Rhodamine B was tested under visible-light irradiation.
