TL;DR: In this article, a 2-methylquinoline adduct with urea is decomposed in the presence of an aqueous solution of a nonionic surfactant, e.g. polyoxyethylene octyl phenol ether, having an HLB of 13-14, preferably in a concentration of 0.01-0.40%, and an alkybvenzene or methyl isobutyl ketone, which will dissolve the aqueously solution of the surfactants and 2- methylquinoline but is substantially insoluble in water under heating to
Abstract: PURPOSE:To obtain the titled compound, by separating 2-methylquinoline capable of readily forming an adduct with urea from quinoline, isoquinoline, 8-methylquinoline, etc. in the form of the adduct, purifying the adduct, and decomposing the purified adduct in an aqueous solution of a surfactant under heating. CONSTITUTION:A 2-methylquinoline adduct with urea is decomposed in the presence of an aqueous solution of a nonionic surfactant, e.g. polyoxyethylene octyl phenol ether, having an HLB of 13-14, preferably in a concentration of 0.01- 0.40%, preferably in the presence of a solvent, e.g. an alkybvenzene or methyl isobutyl ketone, which will dissolve the aqueous solution of the surfactant and 2- methylquinoline but is substantially insoluble in water under heating to give the 2- methylquinoline. USE:A raw material for a quinophthalone dye or pigment.

TL;DR: In this article, a carrier for electrophotographic dry type developer is obtained by dipping the iron powder serving as the core material in the resin solution in which silica fine powder, a epoxy resin and a polyamide resin and if necessary, other resin or an additive are dissolved in a solvent such as methyl isobutyl ketone, xyelen, n-butanol, methyl cyclohexanone and methyl cycloenanone or those mixed solvent.
Abstract: PURPOSE:To obtain a coating carrier having good adhesive properties to an iron powder core material and sufficient mechanical strength, by providing a coating layer in which an epoxy resin contg fine powder of silica is cured by a polyamide resin on the surface of the core material CONSTITUTION:A carrier for electrophotographic dry type developer is obtained by dipping the iron powder serving as the core material in the resin solution in which silica fine powder, a epoxy resin and a polyamide resin and if necessary, other resin or an additive are dissolved in a solvent such as methyl isobutyl ketone, xyelen, n-butanol, methyl cyclohexanone and methyl ethyl ketone or those mixed solvent The substance having 90-410m /g surface area by a BET method is preferable as the silica fine powder The iron powder having 30-200mu particle diameter is preferable as the core material, and the material in which the surfaces of reduced iron powder and atomized iron powder, etc are subjected to oxidizing treatment is used

TL;DR: In this article, the authors proposed a method to obtain the title coating material which is excellent in resistance to electrolysis by seawater and can maintain the effect of preventing the adhesion of marine organisms over a wide area for a long period of time, by using a specified copolymer resin, a conductive filler and a solvent as the constituents.
Abstract: PURPOSE:To obtain the title coating material which is excellent in resistance to electrolysis by seawater and can maintain the effect of preventing the adhesion of marine organisms over a wide area for a long period of time, by using a binder comprising a specified copolymer resin, a conductive filler and a solvent as the constituents. CONSTITUTION:The title coating material contains: a binder comprising a copolymer resin which consists at least of 80-98.5wt.% methyl methacrylate component, 1-15wt.% of at least one monomer component selected from among (meth)acrylic esters (except methyl methacrylate) (e.g. butyl methacrylate), and 0.5-5wt.% of at least one monomer component selected from among an unsaturated dicarboxylic acid, a phosphoric ester, a sulphonic ester, an aminated vinyl monomer and an epoxidized vinyl monomer (e.g. maleic anhydride), the total of these components accounting for at least 90wt.% of the copolymer; a conductive filler (e.g. graphite powder); and a solvent (e.g. toluene and methyl isobutyl ketone).
