“…It was found that water formed during the reaction had a negative effect on Downloaded by [Princeton University] at 04:47 17 September 2013 the formation of dichloropropanol. In this aspect, Song et al discovered that in situ absorption of water by an absorbent (e.g., silica gel) during the reaction enhanced the yield of dichloropropanol (395). Particularly, a combination of gaseous hydrogen chloride, heteropolyacid catalyst, absorbent, and silica gel resulted in the significant enhancement of dichloropropanol formation (389).…”

The article underlines and discusses the state-of-the-art accomplishments in the catalytic conversion of glycerol (1,2,3-propanetriol) to fuels and value-added chemicals in the past five years (2008)(2009)(2010)(2011)(2012). The reactions include steam reforming, aqueous-phase reforming, hydrogenolysis, oxidation, dehydration, esterification, etherification, carboxylation, acetalization, and chlorination. Typical products are hydrogen, propanediols, dihydroxyacetone, glyceric acid, acrolein, glyceride, polyglycerol, glycerol carbonate, acetals, ketals, and epichlorohydrine. Recent studies on the catalysts, reaction conditions, and possible pathways are primarily discussed. They indicate that major breakthroughs are achieved by the use of multifunctional catalysts, process intensification and integrated reactions. Literature survey suggests that future work on the catalytic conversion of glycerol for commercial goals particularly requires new catalysts, innovative reactor engineering, and close multidisciplinary partnership.

In this review article various applications and preparation methods of copper chromite catalysts have been discussed. While discussing it is concluded that copper chromite is a versatile catalyst which not only catalyses numerous processes of commercial importance and national program related to defence and space research but also finds applications in the most concerned problem worldwide i.e. environmental pollution control. Several other very useful applications of copper chromite catalysts are in production of clean energy, drugs and agro chemicals, etc. Various preparation methods about 15 have been discussed which depicts clear idea about the dependence of catalytic activity and selectivity on way of preparation of catalyst. In view of the globally increasing interest towards copper chromite catalysis, reexamination on the important applications of such catalysts and their useful preparation methods is thus the need of the time. This review paper encloses 369 references including a well-conceivable tabulation of the newer state of the art.

“…To remove the unwanted glycerol from the wanted biodiesel, glycerol may also be used as a reactant in a chemical reaction for the production of dichloropropanol. The reaction is conducted at high agitation speed in order to avoid mass transfer limitation between glycerol and hydrochloric acid gas (Song et al, 2009). To remove the unwanted side products (e.g.…”
