标题:1-(Phenylamino)Pseudo-Mauveine: A New Water Soluble Phenazine Dye
摘要:1-(Phenylamino)Pseudo-Mauveine Was Prepared By The Oxidation Of 1,3,5-Tris(Phenylamino)Benzene And P-Phenylenediamine With Potassium Dichromate. The Absorption Maximum Of 535 Nm Is Shifted Hypsochromically By About 20 Nm Compared To That For Pseudo-Mauveine. Condensation Of 1,3,5-Tris(Phenylamino) Benzene With 4-Nitrosodiphenylamine Under Strongly Acidic Conditions Gave 1,3,7-Tris(Phenylamino)-5-Phenylphenazinium Sulfate And 10-Phenyl-6,8-Bis(Phenylamino)-2,10-Dihydrophenazin-2-One.

摘要:A silica-containing material related to zeolites and referred to hereinafter as FU-1 has the composition 0.6 to 1.4 R 2 O.Al 2 O 3 .over 5 SiO 2 .O to 40 H 2 O, (where R is a monovalent cation or 1/n of a cation of valency n) and is characterized inter alia by its X-ray diffraction pattern. It can be made by hydrothermal synthesis in presence of methylated quaternary onium compounds. It is useful as a catalyst for hydrocarbon conversion reactions, especially isomerization of xylenes.

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.
