121 Nonlinear optical element JP29339887 1987-11-20 JPH01134436A 1989-05-26 ITO YUZO; TERAO HIROSHI; ONO YOSHIYO; ARAYA SUKEKAZU; ISOGAI MASATO; TSUNODA ATSUSHI
PURPOSE:To obtain a nonlinear optical element which has a large nonlinear optical constant and for which a material of a short cut-off wavelength is used by incorporating xanthone which is added with at least either of an electron- withdrawing group or electron-donating group into a medium to which light is projected. CONSTITUTION:The medium of the nonlinear optical element having the medium to which the light is projected contains the xanthone which is added with at least either of the electron-withdrawing group or electron-donating group and is expressed by the formula I. The conjugation of pi electrons is no longer uniform by the presence of the oxygen atoms in the rings according to the nonlinear optical element provided with such medium. As a result, the cut-off wavelength does not increase. However, the polarization is not so much affected even if there are the atoms to part the uniform distribution condition of the electrons within the molecule. The polarization is thus excellent as regards the nonlinear optical performance. The nonlinear optical element for which the material having the short cut-off wavelength and large nonlinear optical constant is obtd.
122 Production of tetrachloroanthraquinone JP26540287 1987-10-22 JPH01110642A 1989-04-27 OYAMA TSUKASA; TAKUMA HIROSUKE; AIGA HIROSHI
PURPOSE:To obtain the above substance substituted at 1,4,5,8-positions simply, inexpensively and in high yield, by chlorinating alpha-position dichloroanthraquinone with a chlorine gas in the presence of a very small amount of iodine in fuming sulfuric acid. CONSTITUTION:Dichloroanthraquinone (1,4-, 1,5- or 1,8-dichloroanthraquinone) as a raw material is chlorinated in a solvent of fuming sulfuric acid in the presence of 0.5-0.6wt.% based on the raw material of iodine as a reaction initiator at 25-55 deg.C (preferably 35-45 deg.C) for 5-15hr by introducing a chlorine gas to the reaction solution to give 1,4,5,8-tetrachloroanthraquinone. The fuming sulfuric acid has 15-40wt.% (preferably 20-30wt.%) SO3 concentration. After the reaction, the reaction solution is diluted into 95-98wt.% sulfuric acid concentration, filtered and separated to give the aimed substance. The above substance is useful as an intermediate for synthetic dye and dyestuff material.

PURPOSE: To facilitate extraction and to obtain paprika pigment for food additives, without an offensive smell or taste, by treating a product of paprika oranges, pretreated with an aqueous caustic alkali, with a specific aqueous metal salt, and by pulverizing the resulting solid. CONSTITUTION: Paprika oranges are pretreated with a 15W50wt% aqueous caustic alkali in the presence of an antioxidant, e.g. natural vitamin E, to prevent the decomposition of the pigment, at 90W100°C for 2W7hr. The soapy solid material thus obtained is dissolved in water to form a uniform solution. A 20W50wt% aqueous solution of a water-soluble calcium or magnesium salt, preferably a chloride, is added to the solution and if necessary heated at 60W80°C. After cooling, the solid is taken out and dried at 50°C or below, and extracted with an organic solvent, e.g. acetone, to give the objective pigment. COPYRIGHT: (C)1980,JPO&Japio
