    摘要: Disclosed is an improved process wherein coal particles are beneficiated by froth flotation under coal froth flotation conditions to separate the desired coal particles from remaining unwanted ash and like gangue material. The improvement of the present invention comprises conducting the froth flotation in the presence of an ester-alcohol frothing agent. The preferred ester-alcohol frothing agents are reaction products of C 1 -C 10 mono-basic carboxylic acids and diols wherein the total number of carbon atoms range from about 6-19 and monocarboxylic acid esters of polyoxyalkylene glycols which can contain up to 25-30 carbon atoms.

    摘要: The present invention is directed to polyamines represented by the following general structure:
    where
    R is an organic group,
    R' is H or CH₃, and
    x=0 -3. Tri, tetra, penta and hexa amines, accordingly, are disclosed.
    The method for making the novel polyamines comprises a multi-step reaction that commences in step (a) with the cyanoethylation of a primary amine, R-NH₂, with acrylonitrile under cyanoethylation conditions to form an aminonitrile of the structure R-NH-CH₂-CH₂-CN. The aminonitrile in step (b) is methylated by reaction with formic acid and formaldehyde under Leuckart reaction conditions to form a monomethyl aminonitrile of the structure R-N(CH₃)-CH₂-CH₂-CN. The monomethyl aminonitrile then in step (c) is reduced, preferably by hydrogenation under hydrogenation conditions, to form a monomethyl diamine of the structure R-N(CH₃)-CH₂-CH₂-CH₂-NH₂. The monomethyl diamine then in step (d) is chain extended again by cyanoethylation with acrylonitrile under cyanoethylation conditions to form a monomethyl diaminonitrile of the structure R-N(CH₃)-CH₂-CH₂-CH₂-NH-CH₂-CH₂-CN. Finally, the monomethyl diaminonitrile in step (e) is reduced, preferably by hydrogenation under hydrogenation conditions to form the novel polyamine. Repeating step (b) results in R' being a methyl group. Repeating steps (d) and (e) extends x up to 4.

    摘要: Disclosed is a process for recovering gallium values contained in a basic aqueous solution by liquid/liquid extraction thereof. The liquid/liquid extraction process comprises contacting the basic aqueous solution with a water-immiscible, organic phase comprising a substituted hydroxyquinoline dissolved in an organic solvent therefor whereby gallium is extracted into the organic phase. Thereafter, the organic phase is separated from the basic aqueous phase and the gallium recovered from the separated organic phase. The improvement in process of the present invention comprises the organic phase further comprising dissolved therein an organic dioxime compound.
