专利号:US-3772268-A 优先权日:1971-12-20 标题 :Purification of copper contaminated dye compounds using di(hydroxyalkyl)sulfides 发明人:GILES R; STRALEY J 权利人:EASTMAN KODAK CO 摘要:COPPER IMPURITIES IN DYE COMPOUNDS ARE REMOVED BY CONTACTING SUCH A CONTAMINATED COMPOUND WITH A DI(HYDROXYALKYL)SULFIDE AND RECOVERING THE DYE SUBSTANTIALLY FREE OF COPPER. THE PROCESS CAN BE EMPLOYED IN CONJUNCTION WITH THE SYNTHESIS OF CAYNO SUBSTITUTED DYES BY CYAMIDE DISPLACEMENT REACTIONS WHICH EMPLOY COPPER AS A CATALYST. THE PURIFICATION PROCESS RESULTS IN CERTAIN ADDITION COMPOUNDS OF A CUPROUS OF CUPRIC SALT AND THE DI(HYDROXYALKYL)SULFIDE.
专利号:EP-4206236-A1 优先权日:2021-12-28 标题 :Compounds, their synthesis and compositions comprising the compounds for enhanced deposition of polymers onto hair surfaces 发明人:BREAKSPEAR STEVEN; NÖCKER BERND; WEITZEL JOHANNA; PAEZ JULIETA; PEARSON SAMUEL; BRÜCK STEFAN; CAMPO ARANZAZU DEL 权利人:KAO CORP 摘要:The present invention is on polymers derivatized with an organic deposition-enhancing group for their enhanced deposition onto keratin fibers, especially human hair. The deposition-enhancing group is a di-hydroxyl phenolic compound with a spacer alkyl group bound to a reactive amine or carboxyl group, which reacts with one of the hydroxyl, carboxyl, primary and secondary amine groups on the polymeric backbone. The invention is on the method of synthesizing such compounds and compositions comprising the compounds.
专利号:US-2023271983-A1 优先权日:2020-07-29 标题 :Functionalized isonitriles and products, preparation and uses thereof 发明人:SOTELO PÉREZ EDDY; AZUAJE GUERRERO JHONNY ALBERTO; MAJELLARO MARIA 权利人:UNIV SANTIAGO COMPOSTELA 摘要:The present invention relates to functionalized isonitrile compounds, formed by means of multicomponent environmentally friendly reactions, suitable for coupling to functional molecules such as biomolecules, APIs, chromophore and fluorophore molecules. The invention also relates to conjugates between said isonitrile compounds and functional molecules, which are useful in the synthesis of pharmaceutic drugs or tools, fluorescent molecules and labels, polymeric smart materials. The invention furthermore provides a kit for the in-vitro preparation of the functionalized isontrile compounds and conjugates. The invention also contemplates the medical use of said compounds and conjugates.
