Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Environmental Chemical Engineering called Non-catalytic and catalytic ozonation of simple halohydrins in water, Author is Gounden, Asogan N.; Singh, Sooboo; Jonnalagadda, Sreekantha B., which mentions a compound: 96-13-9, SMILESS is OCC(Br)CBr, Molecular C3H6Br2O, Reference of 2,3-Dibromo-1-propanol.
This study compares degradation of two hazardous halohydrins, namely 2,3-dibromopropan-1-ol (2,3-DBP) and 1,3-dichloro-2-propanol (1,3-DCP) by non-catalytic ozonation in acidic, neutral and basic water and catalytic ozonation with Co loaded on Fe prepared by (i) co-precipitation (Co-ppt) and (ii) a simple phys. mixing (Mixed) method. The brominated halohydrin showed a higher reactivity with ozone than the chlorinated halohydrin. With uncatalyzed ozonation, dehalogenation rate of both pollutants improved with increase in hydroxide ion concentration, however, complete removal of total organic carbon (TOC) and efficient organic byproduct (Org-BP) minimization could not be achieved. Bromide ion oxidation to bromate ion was slower in acidic water, but increased as the hydroxide ion content increased. Ozonation in the presence of Fe:Co (Co-ppt) and Fe:Co (Mixed) catalyst enhanced substrate degradation, TOC removal and considerably minimized Org-BP formation. BET and SEM data revealed that Fe:Co (Co-ppt) catalyst has better textural properties compared to Fe:Co (Mixed) catalyst, and it displayed superior catalytic activity for degradation of toxic pollutants and Org-BP minimization. The Fe:Co (Mixed) catalyst was able to significantly suppress the formation of toxic bromate through lowering of solution pH from 6.8 to 5.7. Unlike bromide, the chloride ion was found be refractory during ozonation. NH3-TPD anal. and pZc values indicate that Fe alone has negligible acidic sites, while 9:1 Fe:Co (Co-ppt) has more acidic sites (6 cm3 g-1 STP) than 9:1 Fe:Co (Mixed) (2 cm3 g-1 STP) catalyst, hence promoting the decomposition of ozone to hydroxyl radicals on the Fe:Co (Co-ppt) surface.
