    摘要: A method of preparing a hydroxy-functional polyether comprising contacting (a) a hydroxy-functional polyether containing less than or equal to about 200 ppm of a Group IA or Group IIA metal ion, and (b) an acid. Preferably the contact is carried out under reaction conditions such that a salt, which is not suitable to significantly promote trimerization reactions if the hydroxy-functional polyether is reacted with an isocyanate compound, is formed. The amount of acid is sufficient to essentially neutralize residual basic catalyst without requiring additional solids removal steps prior to use of the hydroxy-functional polyether in various applications, such as production of polyurethanes and related products, in which enhanced trimerization may not be desirable. Additional acid may also be added to convert propenyl ether units present in the polyether's backbone to propionaldehyde and the corresponding diol.

    摘要: This invention is a method for producing phase change material (PCM) chemicals containing fatty acids or fatty-acid derivatives. These derivatives (1) are renewable, being produced by biomass or livestock such as cattle, (2) can be manufactured at low to moderate prices, and (3) can be manufactured in a variety of ways to produce PCM chemicals effective at several temperatures of interest in climate control and food maintenance. Unlike paraffin PCM chemicals that are largely limited to fractions available in either crude oil or irreversible chemical synthesis processes, the ester bond chemistry of triglycerides (fats and oils) is reversible allowing repeated reaction until the desired PCM chemicals combinations are synthesized and isolated. This method in a process based on contacting of reactants, reversible ester bond chemistry, separation of fractions with the desired latent heat properties, and recycle of those fractions that do not have the desired latent heat properties.

    摘要: A compact magnetic levitation vehicle or car provides passenger comfort consistent with automobiles and travels suspended on ferromagnetic rails in evacuated tubes of minimal radial dimension extending between vehicle loading and unloading stations or at atmospheric conditions. A pair of guides extend outwardly along opposite sides of the vehicle and contain magnetic elements. Electrically conductive, ferromagnetic, magnetic, or electromagnetic sections in the rails correspond to the magnetic elements in the vehicle guides. Linear motors or controlled interaction with rail members provide propulsion and braking. Extensive portions of the evacuated tubes are provided with two sets of rails, one set of rails functionally located above the other. Rail switching is accomplished by selectively interacting with alternative levitation rails which are located at switching locations. Tube evacuation may be supplemented by vacuum pumps on the vehicle to draw in air during travel. The vehicle may have turbines which draw in air and exhaust compressed gases into cylinders.

    摘要: A reactive-separation process converts glycerin into lower alcohols, having boiling points less than 200° C., at high yields. Conversion of natural glycerin to propylene glycol through an acetol intermediate is achieved at temperatures from 150° to 250° C. at a pressure ranging from 1 and 25 bar. The preferred applications of the propylene glycol are as an antifreeze, deicing compound, or anti-icing compound. The preferred catalyst for this process in a copper-chromium powder.
