چکیده

A novel biodiesel named rapeseed oil monoester of ethylene glycol monomethyl ether is developed. This fuel has one more ester group than the traditional biodiesel. The fuel was synthesized and structurally identified through FT-IR and P(1P)H NMR analyses. Engine test results show that when a tested diesel engine is fueled with this biodiesel in place of 0# diesel fuel, engine-out smoke emissions can be decreased by 25.0%-75.0%, CO emissions can be reduced by 50.0%, and unburned HC emissions are lessened significantly. However, NOx emissions generally do not change noticeably. In the area of combustion performance, both engine in-cylinder pressure and its changing rate with crankshaft angle are increased to some extent. Rapeseed oil monoester of ethylene glycol monomethyl ether has a much higher cetane number and shorter ignition delay, leading to autoignition 1.1°CA earlier than diesel fuel during engine operation. Because of certain amount of oxygen contained in the new biodiesel, the engine thermal efficiency is improved 13.5%-20.4% when fueled with the biodiesel compared with diesel fuel.

Determination of Icing Inhibitors (Ethylene Glycol Monomethyl Ether and Diethylene Glycol Monomethyl Ether) in Ground Water by Gas Chromatography-Mass Spectrometry

A gas chromatography/mass spectrometric assay method has been developed for the simultaneous determination of icing inhibitors, ethylene glycol monomethyl ether and diethylene glycol monomethyl ether in ground water contaminated with JP-8. Ethylene glycol monobutyl ether and ethylene glycol monoethyl ether were used as the internal standard and surrogate, respectively. 100 mL of ground water wa...

Further studies on the toxicology of the glycol ethers with emphasis on rapid screening and hazard assessment.

The discovery that ethylene glycol monomethyl ether (EGME) could affect the testis and the developing fetus in laboratory animals prompted further work to understand the effect of EGME and to examine additional glycol ethers to see if they showed EGME's reprotoxicity. Propylene glycol monomethyl ether (PGME) was shown not to cause testicular atrophy or to affect the development of rats at 600 p...
