标题:Method for producing alkaline earth sulphate nanoparticles

权利人:NANOSOLUTIONS GMBH
摘要:The invention relates to synthesis of nanoparticles, in particular to methods for producing nanoparticles with networks consisting of Z sulphate (Z=magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) or the binary mixtures thereof). The inventive method consists in synthesising the nanoparticles by crystal growth from an ion Z source and a sulphate ion source in a liquid phase mixture. The invention produces Z sulphate nanoparticles having a small diameter and uniformly dispersible in water or other solvents in a simple way. Co-ordinating solvents like glycerine, glycol ethylene and other polyethylene glycols, polyalcohols or dimethylsulphoxide (DMSO) are used for the synthesis mixture.

摘要:PCT No. PCT/JP83/00263 Sec. 371 Date Apr. 4, 1984 Sec. 102(e) Date Apr. 4, 1984 PCT Filed Aug. 12, 1983 PCT Pub. No. WO84/00755 PCT Pub. Date Mar. 1, 1984.This invention provides novel aminopolyol derivative represented by the general formula (I) wherein each of R and R' represents a hydrogen atom, or an alkyl or aryl group or R and R', taken together, form an alkylene group, R1 represents a lower alkyl group, R2 represents a hydrogen atom or an acyl group, and R3 represents a lower alkyl group; and a process for production thereof. The aminopolyol derivatives of formula (I) are useful as intermediates for the synthesis of amino sugars such as 3-epi.daunosamine, acosamine, ristosamine and daunosamine which is the sugar moiety of daunomycin useful as an anti-cancer agent.

摘要:The invention provides novel sulphonated chiral phosphines of the formula: ##STR1## in which R represents an alkyl radical, a cycloalkyl radical optionally substituted with an alkyl radical, a cycloalkylalkyl radical optionally substituted with an alkyl radical, a phenyl, phenylalkyl, binaphthyl or binaphthylalkyl radical, in which the alkyl, cycloalkyl, phenyl and binaphthyl radicals, and the alkyl portions of the other radicals, can be substituted by a radical of general formula: ##STR2## R 1 represents an alkyl, cycloalkyl, phenyl, or phenylalkyl radical, Ar represents a phenyl or naphthyl radical, m + represents a proton or alkali metal ion or alkaline earth metal ion, m=1 or 2, n=0, 1 or 2, p=1 or 2, (p+m) ≦3, and R and R 1 can be chiral or achiral. These chiral phosphines form water-soluble metal complexes useful as catalysts in asymmetric organic synthesis.
