标 题 :Method of recovering metals
发明人：PANG MICHAEL

摘要:Copper is recovered from ores, or slags, or tailing piles, in which the cupriferous material is finally subdivided by leaching with a dilute aqueous acidic leach solution, the leach solution separated from insolubles, and the copper extracted using as extractant a long chain alkyl quinaldinic acid, such as 6dodecylquinaldinic acid, in an organic solvent system, such as 75/25 kerosene/aromatic petroleum fraction and which may contain up to 25 percent of a C9 to C14 alkanol, the organic extractant in solution separated from the aqueous leach solution, and the copper stripped from the organic extractant by strong sulfuric acid, the copper being stripped as copper sulfate in acid solution, from which copper is recovered as electrolytic grade copper by electrolysis. New quinaldinic acids and methods of synthesis are disclosed.

标题 :Process for preparation of azo dyestuffs by coupling in presence of aromatic sulphonic acid-formaldehyde reaction product

权利人:BAYER AG
摘要:Dyestuff dispersions and dyestuff solutions free from salt or at least having a low salt content are obtained in that the diazotization is carried out with addition of free dispersing agent acid to which, after the synthesis, either no basic agents are added or basic agents are added only up to a pH value of 3. The disclosed process gives dyestuff compositions of low salt content and results in readily dispersible dyestuffs when water insoluble dyestuffs are prepared and stable solutions when water soluble dyestuffs are prepared. The process is widely applicable and chemical constitution of the dyestuffs is conventional.

摘要:A method has been developed for the post-synthesis separation of nanotubes by size and/or type. Solubilized, functionalized nanotubes are passed over a GPC column such that length-separated fractions are collected. These length-separated fractions can then further be separated by diameter or type. Particularly useful are methods for separating nanotubes into metallic and semiconducting fractions.

摘要:N-substituted, N-(polysubstituted-4-piperidinyl)- alpha -(3,5-dialkyl-4-hydroxyphenyl)- alpha , alpha -disubstituted acetamide ('3,5-DHPIPA') generates an exceptionally stable hindered acetamide aroxyl radical which is far more stable than the 'blue aroxyl radical' derived from 2,4,6-tri-tert-butyl-phenol, which radical was heretofore adjudged the standard of superior stability and resistance to degradation due to heat, oxygen and light, the compound having been specifically disclosed as a uv-stabilizer. The hindered aroxyl amide radical which is at least ten times more stable than the 'blue aroxyl radical' heretofore deemed stable, may be generated by 3,5-DHPIPA compounds prepared by a peculiarly effective synthesis known as the ketoform reaction. This ketoform reaction is unexpectedly well-adapted to produce the 3,5-DHPIPA compounds which we have been unable to produce by any other synthesis known to us. The stability of the hindered aroxyl amide radical inculcates an organic material in which a 3,5-DHPIPA compound is dispersed, with excellent stability. The use of a combination of 3,5-DHPIPA compounds, or a combination of a 3,5-DHPIPA compound with with known stabilizers, particularly the phosphites and benzophenones, in a small but stabilizing amount, provides especially effective stabilization in polyolefins and a host of other synthetic resinous materials.
