The optimum reaction conditions were: 110掳C, molar ratio of methyl 2-naphthyl ketone to ethylene glycol 1:2, catalyst loading 0.02g/cm3, speed of agitation 800rpm, and time 3h. Reaction mechanism and kinetic model were developed. The methodology was extended to different substrates, and ...
Since precipitation of calcium oxalate crystals also occurs in the lungs, one could postulate that these changes may be an inflammatory reaction related to this precipitation. Although pulmonary edema has been suggested to occur in ethylene glycol poisoning, this is an unsubstantiated diagnosis, despite...

Properties vary with molec-ular weight. 6.16 Production Methods Polyethylene glycol polymers are formed by the reaction of ethylene oxide and water under pressure in the presence of a catalyst. 6.17 Indications Polyethylene glycol (Miralax) is another osmotic laxative that is colorless and tasteless ...
Separation of a mixture of water, methylethyl ketone, and ethylene glycol mono-n-butyl ether into a) water and b) methylethyl ketone containing ethylene glycol mono-n-butyl ether of the disclosure: The invention relates to a process for the separation of a mixture of water, methylethyl ketone...
An aqueous, solventborne or solvent-free pigment preparation containing a block polyether of styrene glycol and ethylene glycol, a ketone-aldehyde resin inorganic or organic pigments and adjuvants; antifoaming agents; low viscosity; dispersants with binder properties; paints; varnishes; adhesives, inks...
This invention is concerned with improving the ethylene glycol production capabilities of the metal carbonyl catalyzed reaction between carbon monoxide and hydrogen by conducting the reaction such tha
B. A reaction converter was charged with 1680 parts of urea and 434 parts of ethylene glycol, giving a mole ratio of 4:1. The reaction was carried out under conditions substantially identical with those employed in A, and 830 parts of the crude melt were produced. This crude melt was sub...
A series of sulfonated poly(ether ether ketone)-poly(ethylene glycol) cross-linked interpenetrating polymer network/SiO2 nanocomposite membranes are developed for fuel cell application. Poly(ethylene glycol) is used as cross-linker to induce interpenetrating polymer network structure, and simultaneously, ...
PEG is poly(ethylene glycol); and X, m and Z are as defined above. The polymers of the invention, whether activated or not, can be purified from the reaction mixture. One method of purification involves precipitation from a solvent in which the polymers are essentially insoluble while the re...
