The OMEGA process only mono ethylene glycol advanced process is a process of the Royal Dutch Shell to produce ethylene glycol Mono ethylenlglycol from ethylene oxide , carbon dioxide as catalyst and water with high selectivity . Process The traditional process of monoethylene glycol MEG production is by reaction of ethylene oxide with water. The product of the first reaction stage, MEG, reacts with ethylene oxide on to di diethyleneglycol and triethylene glycol , which makes a distillation work up necessary. The selectivity to MEG is about 90 . In the OMEGA process, the ethylene oxide is first converted with carbon dioxide CO sub 2 sub to ethylene carbonate to then react with water in a second step to selectively produce monoethylene glycol . The carbon dioxide is released in this step again and can be fed back into the process circuit. The carbon dioxide comes in part from the ethylene oxide production, where a part of the ethylene is completely oxidation oxidized . 1 math C 2H 4O CO 2 longrightarrow C 3H 4O 3 math small Ethylene oxide reacts with carbon dioxide to ethylene carbonate small . 2 math C 3H 4O 3 H 2O longrightarrow HO C 2H 4 OH CO 2 math small ethylene carbonate reacts with water to mono ethylene glycol and carbon dioxide small .

Chafing fuel is a generic term for various products that are used for heating food. These products often contain methanol , ethanol , or diethylene glycol , as these may be burned safely indoors. These fuels are also used for emergency heating, outdoor cooking, and fondue . Types of fuel Image Methanolgelfuel.JPG thumb right The first two fuels are similar with regards to consistency, both having a gel form viscosities can vary with brand , operating procedures, and product design. Ethanol is a more energetic fuel giving 1300kJ mol heat of combustion compared to methanol s 726kJ mol. The common gel methanol or ethanol chafing fuel is contained in a steel can with a resealable plug lid in sizes based on burn times. Two, four, and six hour burn times are the most common sizes of methanol and ethanol chafing fuels available. The colour of the fuel being used can also vary among manufacturers. Image DEGfuel.JPG thumb left Diethylene glycol chafing fuel differs because the fuel itself is unflammable. The container housing the fuel is equipped with a Candle wick wick to allow the chemical to be combusted. It is considered safer than methanol or ethanol gel fuels because spilled DEG fuel will not combust. The fuel is in a liquid form and thus the canister in which it is contained usually differs by having a more leak resistant screw cap rather than a plug. DEG has a higher heat of combustion then ethanol or methanol gel at 2155 kJ mol. ref http www.meglobal.biz media FastFacts DEG.pdf ref As a camping fuel There are many advantages and disadvantages to using chafing fuels for camping purposes. The lightweight size and the burn time per gram of fuel weight received from this method is very high. Chafing fuels are also clean burning, quiet, safer, and readily available than most other portable heat sources. However their main disadvantage is their lower heat output when compared to popular alternatives such as white gas and kerosene . This results in longer cooking times. cn ... more details
mergeto Polyethylenimine date May 2012 Polyethylene amine is a polymer of aziridine with the molecular formula CH sub 2 sub CH sub 2 sub NH sub n sub . It is a structural analogue of polyethylene glycol with NH in place of oxygen atoms. It is produced by the polymerization of aziridine. Oligomeric polyethylene amines with a small number of units are used as Curing chemistry curing agents for epoxy resin s. They are water soluble. The gelling properties of higher polyethylene amines are useful for resin formulas that require high viscosity during application and curing. Polyethylene amine can form gel s. Due to the rich content of easily protonated amine groups, in acidic solutions it behaves as a polyelectrolyte polycation . Polyethylene amine may have applications as a component of ion exchange resin s. High selectivity semipermeable membranes, permeable for carbon dioxide and retaining oxygen , can be made from this material as well. These are important for life support systems. http www.dsls.usra.edu meetings bio2001 pdf EVAcomplete.pdf See also Ethylene diamine Diethylene triamine Triethylene tetramine Polyethylenimine Category Organic polymers Category Polyelectrolytes Category Polyamines ... more details

Ref Kishner1911 Ref Wolff1912 Image Wolff Kishner Summary V.1.svg center 400px The Wolff Kishner reduction The method originally involved heating the hydrazine with sodium ethoxide in a sealed vessel at about 180 C. Other bases have been found equally effective. Diethylene glycol DEG is usually used as solvent. Several reviews have been published. Ref Todd1948 Ref Hutchins1991 Reaction mechanism The most probable mechanism involves the elimination of an alkyl anion as the final step Image Wolff Kishner Huang Reduction.png center 600px The mechanism of the Wolff Kishner reduction The mechanism first involves the formation of the hydrazone in a mechanism that is probably analogous to the formation of an imine . Successive deprotonations eventually result in the evolution of nitrogen. The mechanism can be justified by the evolution of nitrogen as the thermodynamic driving force. This reaction is also used to distinguish between aldehydes and ketones.
