Abstract: Alkylene oxide adducts of organic compounds having active hydrogen atoms are prepared by a process which comprises contacting and reacting an alkylene oxide reactant comprising one or more vicinal alkylene oxides with an active hydrogen containing reactant comprising one or more compounds having active hydrogen atoms in the presence of a catalytically effective amount of one or more compounds of one or more of the rare earth elements. The product alkoxylates are known to be useful, for instance, as nonionic surfactants, wetting and emulsifying agents, solvents, and chemical intermediates.

Abstract: Certain mixtures of the ethylene oxide adducts of higher carbon number tertiary thiols, having a reduced content of free thiols and lower (i.e., 1 to 3 mol) ethylene oxide adducts, exhibit improved detergency performance, particularly in high temperature laundry applications.

Abstract: Alkylene oxide adducts of higher alkanols are prepared by a process which comprises contacting and reacting an alkylene oxide reactant comprising one or more C.sub.2 to C.sub.4 vicinal alkylene oxides with an alkanol reactant comprising one or more C.sub.6 to C.sub.30 alkanols in the presence of a catalytically effective amount of a catalyst which combines (i) one or more phosphorus-containing acids with (ii) one or more aluminum compounds selected from the group consisting of aluminum alcoholates and aluminum phenolates, the relative molar ratio of component (i) to component (ii) being in the range from about 0.1:1 to 2.5:1. Alkanol alkoxylates, and particularly alkanol ethoxylates, prepared in this manner are characterized by a relatively narrow-range distribution of alkylene oxide adducts and by a relatively low content of residual alkanol. The products of this process are nonionic surfactants, particularly useful as components of detergent formulations.

Abstract: Alkylene oxide adducts of higher alkanols are prepared by a process which comprises contacting and reacting an alkylene oxide reactant comprising one or more C.sub.2 to C.sub.4 vicinal alkylene oxides with an alkanol reactant comprising one or more C.sub.6 to C.sub.30 alkanols in the presence of a catalytically effective amount of a catalyst which combines (i) one or more sulfur-containing acids with (ii) one or more aluminum compounds selected from the group consisting of aluminum alcoholates and aluminum phenolates, the relative molar ratio of component (i) to component (ii) being in the range from about 0.1:1 to 1:1. Alkanol alkoxylates, and particularly alkanol ethoxylates, prepared in this manner are characterized by a relatively narrow-range distribution of alkylene oxide adducts and by a relatively low content of residual alkanol.

Abstract: A peanut cleaner for cleaning freshly harvested peanuts in the field includes structure for initially vibrating the peanuts to loosen moist field soil, trash, fines and clinging vine segments therefrom, structure for thereafter subjecting the loosened soil, field trash, fines, vine segments and peanuts to a free fall downwardly along a substantially vertical flow path while subjecting the vertical flow path to a lateral and slightly upwardly inclined flow of at least slightly dehumidified air to thereby blow at least the lighter loosened soil, field trash, fines and vine segments laterally from the vertical flow path of peanuts and still further structure for repeatedly elevating the peanuts from a reticulated support surface therefor and allowing the peanuts to free fall, by gravity, back downwardly onto the reticulated surface to thereby loosen and remove therefrom any remaining clinging soil, field trash, fines and vine segments from the peanuts.
