The present invention concerns a new process and the relative plant for reducing hexavalent chromium contained in the resultant earth after the production of chromium, in order to obtain the transformation from water-soluble compounds into insoluble compounds, the process comprising the phases of mixing...
in particular with heptakis(2,6-di-O-methyl)- beta -cyclodextrin, by dissolving the organic compounds which are insoluble or have only limited solubility in water in an aqueous solution of 1 to 8 mol (calculated per 1 mol of the compound to be dissolved) of dimethyl- beta -cyclodextrin. ...
two compounds were too alkaline and significantly changed the phenol red absorption at 557 nm immediately after addition; ten compounds were insoluble in water, water/ethanol mixes or pure ethanol, and one compound gave
aThese findings indicate that citrate insoluble compounds form in partially ammoniated phosphoric acid in the pH range 0.5 to 2 in the presence of iron andlor aluminum and that in the critical pH range, the citrate-insoluble phosphate increases with time. 这些研究结果表明枸橼酸盐不能溶解的化合...
isinglass, eucollagens, zein, casein, albumin, soya bean protein, peptides, polyalkylene imines and polyvinylamines are converted into water-soluble reactive compounds by reacting them with a di- or polyfunctional reagent under controlled reaction conditions so that a water-insoluble network is not ...
Nickel sulfate and nickel chloride are highly soluble in water, while nickel oxide is insoluble. Nickel subsulfide is poorly soluble, but is more soluble in biological fluids, presumably due to the effects of the proteins and other cellular components. Nickel and its inorganic compounds are not ...
Sulfur Compounds In subject area: Physics and Astronomy Sulfur compounds are chemical substances commonly found in oil and fuels, leading to environmental pollution, reduced efficiency of engines, corrosion of equipment, and catalyst poisoning. Desulfurization processes are employed in refineries to remove...
申请(专利权)人: Hans-Jörg Eibl 发明人: HJ Eibl 国省代号: DE 摘要: The present invention relates to compositions comprising a water-insoluble pharmaceutically active ingredient or a substance having low water solubility, and a compound represented by Structural Formula (I)收藏...
Insoluble in water. A sample of tetra-cresyl ortho silicate as thus produced was placed in a glass container and held at the boiling point in the same manner as described in connection with the phenyl compound described under Example I. Over a period of four weeks the boiling point held at...
The present invention relates to processes for producing immunotoxins (ITs) and cytokines with a reduced ability to promote vascular leakage syndrome (VLS). The invention further relates to ITs and cytokines that have been mutated to lack VLS-inducing amino acid sequences....
