<p>#CMT# #/CMT# Para-tertiary-butyl calix [6] arene is new. #CMT# : #/CMT# Para-tertiary-butyl calix [6] arene (I) of formulae (Ia) or (Ib) is new. R 1, R 3, R 5 = acetyl, amino, phosphate, NO 2, sulfate, carboxylic, (thio)carboxy, (thio)carbamate, 1-60C (preferably 1-30C) alkyl (optionally substituted, and optionally having at least an ethylene or acetylenic unsaturation), 3-12C cycloalkyl (optionally substituted and optionally having at least one ethylene or acetylenic un-saturation), aryl, naphtyl, aryl-(1-30C alkyl), optionally substituted (1-30C alkyl)aryl (where all radicals are substituted by halo, organ metallic radicals, functional group of alcohol, amino, acid or carboxylic ester, sulfonic, sulfuric, phosphoric, phosphonic or hydroxamic, (thio)carbamates, ethers, thiols, epoxy, thioepoxide, isocyanates, isothiocyanates or one carbon of these radicals are optionally replaced by one heteroatom of N, S, P, O, B or As), polymers e.g. polystyrenes, copolymers of chloro and/or bromomethylstyrene and divinylbenzene, polyethers, polyacrylamides, polyglycidyl methacrylates, dextranes, and agaroses, H, or halo. Provided that R 1, R 3 and R 5 are not representing: simultaneously CH 3 in (Ia) or (Ib); simultaneously CH 2COOH in (Ia); and simultaneously CH 2CONHOH in (Ib) Independent claims are included for: (1) a liquid supported membrane comprising (I), where (I) is dissolved in an organic solvent and absorbed on a support; and (2) a material support, which is a para-tertiary-butyl calix [6] arene of formula (IIa) or (IIb). R 1a, R 3a, R 5aR 1 (without provisos) or X-Y 1; X : bivalent radical of 1-60C (preferably 1-30C) akylene, (1-60C alkyl)-arylene, aryl-(1-60C alkylene), aryl(1-60C alkyl)-aryl (where the bivalent radical is substituted by halo, organ metallic radicals, functional group of alcohol, amino, acid, carboxylic, ester, sulfonic, sulfuric, phosphoric, phosphonic or hydroxamic, carbamates, thiocarbamates, ethers, thiols, epoxy, thioepoxide, isocyanates, isothiocyanates or one carbon of these radicals are optionally replaced by one heteroatom of N, S, P, O, B or As); and Y 1mineral, organic or organomineral origin. Provided that at least one of R 1a, R 3a or R 5a is polymer or X-Y 1. #CMT#[Image]#/CMT# #CMT#[Image]#/CMT# #CMT#[Image]#/CMT# #CMT#[Image]#/CMT# #CMT#USE : #/CMT# (I) is useful for the preparation of lipid support membrane or material support. The liquid support membrane and/or material support are useful: for the selective complexation and analysis of the elements of uranium, americium and plutonium or other radio active elements in their cation form; and to remove at least two components of organic, mineral or organomineral molecules or at least a part of the components from a mixture, or to separate the components by a chromatographic method (claimed). #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Components: The support is a support of mineral origin, preferably silica gel, oxides e.g. alumina and zirconia or titanium oxide, organic origin of polystyrenedivinylbenzene, polyethers, polyacrylamides, polyglycidyl methacrylates and/or organomineral origin of silica/dextrane or hydroxyapatite/agarose composites. The support is a particulate support having particle size of 10 nm to 10 mm, preferably 10-50 mu m and a pore diameter of 10-5000 (preferably 100-500)[deg]A. #CMT#ORGANIC CHEMISTRY : #/CMT# Preparation: Preparation of (I) comprises: synthesizing 1,3,5-trimethoxy-para-tertiarybutylcalix[6]arene and 2,4,6-triethylester-1,3,5-trimethoxy-para-tertiary-butylcalix[6]arene (precursor compound) (Iy); and modifying (Iy) by saponification or by substitution of the ethyl ester or carboxylic acid, to give 1,3,5-O-trimethyl-2,4,6-O-tri carboxylic acid-para-tertiary-butyl-[calix6]-arene (representative of (Ia)) or 1,3,5-O-trimethyl-2,4,6-O-tri hydroxamic acid-para-tertiary-butyl-[calix6]arene (representative of (Ib)). Preferred Components: The organic solvent has a boiling point of greater than 60[deg]C and is toluene, preferably xylene, chlorobenzene, ortho-dichlorobenzene, nitrobenzene, 1,4-diisopropyl benzene, hexylbenzene, kerosene, tetrahydropyranne, 1,2,3,4-tetrahydronaphtalene, homologous pentanol and higher alcohols, glycols and their ethers, e.g. diethylene glycol dibutyl ether, esters e.g. methyl benzoate and/or ethers e.g. orthonitrophenyl pentylether or nitrophenyl octylether. #CMT#DEFINITIONS : #/CMT# Preferred Definitions: R 1, R 3, R 5H. #CMT#EXAMPLE : #/CMT# Para-tertiary-butyl calix[6]arene was dissolved in acetone anhydride followed by the addition of potassium carbonate and the suspension was shaken for 3 hours under nitrogen. Excess of methyl iodide was added and the suspension was refluxed for 24 hours under agitation. The acetone was evaporated under vacuum and the residue obtained was solubilized in chloroform. After dissolution, water was added and the biphasic medium was placed under agitation and acidified with concentrated hydrochloric acid (12M). The organic phase was recovered by clarification and washing with water. The organic phase was dried on sodium sulfate anhydride, and filtered. The organic phase was worked up to give 1,3,5-trimethoxy-para-tertiary-butylcalix[6]arene.</p> |
