Use of MgO to Promote the Oxyethylation Reaction of Lauryl Alcohol

Abstract

Synthesis of magnesium hydroxide was performed by the precipitation method with the use of magnesium sulfate and sodium hydroxide. The infiuence of temperature and ratio of reagents was studied. Magnesium hydroxides, and the magnesium oxides obtained from them by thermal decomposition, were analyzed to determine their bulk density, polydispersity and particle size. The magnesium oxide with the largest surface area was tested as a catalyst in the oxyethylation of lauryl alcohol, and shown to be selective but poorly reactive in comparison with commercially available catalysts. Further studies are needed to improve its reactivity.

Treatment of dairy waste by anaerobic co-digestion with sewage sludge

“…Their main biodegradable components are: lactic acid, lactose (so-called "lactic sugar"), fat, and casein. Based on the date in literature [30], as well as chemical knowledge and experience [31][32][33], the authors of presented paper, have proposed the possible directions of biodegradation for the organic waste materials in this experiment; they are shown in the form of chemical reactions (1) to (47). Knowledge about intermediate products of biodegradation of organic matter used as the feed in biogas plants is very important for maximization of the efficiency of anaerobic digestion.…”

“…Their hydrolysis is based on decomposition into glycerol and palmitic acid (18) and linoleic acid (19). The two acids are decomposed in the acidogenic phase into simpler chemical compounds, denoted as A P to G P for palmitic, and A L to H L for linoleic acid (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32). The products of decomposition of the two acids comprise, essentially, the following: ethyl alcohol; 2-oxopropanoic acid; 1,4-butanedioic acid; 2-hydroxypropanoic acid; propan-2-one; methyl alcohol and methanoic acid.…”

Calcination‐Dependent Morphology Transformation of Sol‐Gel‐ Synthesized MgO Nanoparticles

“…Oxide nanomaterials, especially metal oxides, possess exceptional optical, electrical, electronic and chemical properties due to their large surface areas and high absorption efficiency . Magnesium oxide (MgO) has gained significant attention due to its unique properties such as wide band gap, which is an important feature for enhanced catalytic and mechanical properties, low heat capacity, high melting point, dielectric property, high bioactivity against pathogenic bacteria as well as cancerous cells and low cytotoxicity . MgO nanoparticles have found applications in the production of refractories, insulating materials, adsorbents for CO 2 capture, paints, superconductors, and toxic waste remediation ,.…”
