标 题 :Preparation of disperse azo dyestuffs in the presence of alkoxylated acetylenic diols
发明人：DADO GREGORY PAUL
权利人:AIR PROD & CHEM
摘要:The use of alkoxylated acetylenic diol surfactants in the aqueous synthesis of disperse azo dyes provides a simple process for improving filtration properties of dyestuff. The surfactants may be added prior to the coupling step of the synthesis or prior to heat treatment of the dye slurry. Advantages that are realized by incorporation of the surfactants into the synthesis include decreased filtration time, increased solid content in filter cake, improved washing properties of filter cake, and increased dye yield. In addition, for azo dyes that are synthesized as non-heat-stable crystal modifications, the presence of alkoxylated acetylenic diol surfactants in the dye slurry is effective in promoting the conversion of the dye to the desired thermally stable crystal modification.

权利人:SAVANNAH RIVER NUCLEAR SOLUTIONS LLC
摘要:Methods directed to the synthesis and peroxide-modification of nanosized monosodium titanate are described. Methods include combination of reactants at a low concentration to a solution including a nonionic surfactant. The nanosized monosodium titanate can exhibit high selectivity for sorbing various metallic ions.

摘要:The present disclosure generally relates to the synthesis of an alkoxylated cannabinoid using a double metal cyanide (DMC) catalyst. This procedure affords a novel process for preparing water-dispersible and water-soluble versions of cannabidiol (CBD) and other cannabinoids in high yields through mild reaction conditions.

标 题 :Process for the preparation of amines
发明人：OUZIEL PHILIPPE
权利人:CIBA GEIGY CORP
摘要:A process for the preparation of amines of formula (1) wherein the variables are defined as in the claims, which comprises reacting 1 molar equivalent of an amine of formula (2) with 0.8 to 1.5 molar equivalents of an aldehyde of formula R-CHO(3) and 0.8 to 2 molar equivalents of formic acid, in aqueous medium, and adjusting the pH by addition of a mineral acid such that, at the conclusion of the reaction, the pH is in the range from 3 to 7. The compounds obtainable by the process are useful intermediates for the synthesis of dyeing assistants.
