Abstract: Aliphatic alcohol compositions that burn with a luminous flame. Lower aliphatic alcohols such as methanol, ethanol, and propanol burn with an essentially colorless flame. This is particularly hazardous when such alcohols are used as fuels for racing cars or other motor vehicles. If such alcohol fuels ignite during, for example, refueling or following a collision, the fire may initially go unnoticed because of virtually colorless flames. The alcohol compositions of the invention contain alcohol-soluble metal compounds such as compounds of sodium, barium and boron, which impart luminosity to the flames of such alcohol compositions. The alcohol compositions of the invention find utility as fuels for racing cars or other motor vehicles, as fuels for alcohol stoves and in other applications where lack of a luminous flame creates a safety hazard.

Abstract: A continuous process for producing alkali metal alkoxides comprising continuously introducing an aqueous solution of an alkali metal hydroxide into an upper section of a column reactor; continuously vaporizing an alkanol or an alkoxyalkanol of 4 to 18 carbon atoms into a lower section of the reactor at a rate of at least about 2 to 4 moles of alcohol for each mole of alkali metal hydroxide introduced into the reaction zone; reacting the aliphatic alcohol with the alkali metal hydroxide in the reactor; concurrently removing water from the alkali metal hydroxide solution and the alkoxide formation from an upper section of the reactor as an azeotrope formed by excess alcohol and water; continuously condensing and separating the azeotrope into an alcohol phase and a water phase, the water phase being removed from the process and the alcohol phase being returned to the column reactor; and removing a substantially anhydrous reaction product consisting primarily of alkoxide product in excess alcohol from a bottom se

Abstract: A method if provided for continuously hydrolyzing urethane foam in a vertically oriented hydrolysis reactor. In a preferred practice, a bed of foam particles is formed in the reactor. Superheated steam is flowed continuously upward through the bed at a temperature and rate such that only the foam particles then adjacent the bottom of the reactor are hydrolyzed and the bulk of the bed is not fluidized. Unreacted steam heats the unhydrolyzed foam. Liquid hydrolysis products are drained as they are formed to prevent hydrolysis-impeding liquid saturation of unhydrolyzed particles.
Abstract: A process for the continuous production of an alkali metal alcoholate of a higher alcohol which comprises continuously introducing a higher alcohol into a reaction vessel, continuously introducing an alkali metal alcoholate of a lower alcohol into said reaction vessel and continuously and simultaneously distilling over and removing from said reaction vessel lower alcohol which forms.

Abstract: Sodium and potassium alkoxides are produced by reaction of the corresponding metal hydroxide, the corresponding alcohol and calcium oxide in the presence of a suitable surfactant. The suitable surfactants are certain classes of cationics, non-ionics and amphoterics with cationic groupings. The surfactant causes the reaction to proceed much more rapidly and the formed alkoxide remains in solution with calcium hydroxide being formed as a precipitate which can be easily separated from the solution.
Abstract: High molecular weight polyglycerol derivatives, useful as thickening agents for water-based lubricants, are prepared by oxyalkylating a polyglycerol with ethylene oxide or a mixture of ethylene oxide and propylene oxide. The polyglycerol derivatives are characterized as having an average of more than five glycerol units, and in having more than 95% and preferably more than 99% alkylene oxide units. These compounds exhibit excellent shear strength and provide an improved hydrolube when incorporated therein.
