Abstract: PROBLEM TO BE SOLVED: To produce the subject high-purity compound in high yield by cyclizing 2,5-dianilinoterephthalic acid, placing the resultant reactional mixture into a specific solvent, carrying out the direct decarboxylation in the presence of a catalyst and then removing impurities. SOLUTION: (1) 2,5-Dianilinoterephthalic acid represented by formula I (R and R1 are each H, an alkyl, an alkoxy or a halogen) is cyclized to provide a solid mixture containing about 90% 2-anilino-3-carboxyacridone and about 10% quinacridone. (2) The resultant mixture is then mixed with an organic solvent capable of dissolving the objective 2-anilinoacridone represented by formula II without dissolving quinacridone (preferably a eutectic mixture of diphenyl ether with biphenyl) at an elevated temperature. (3) The direct decarboxylation is subsequently carried out in the presence of a decarboxylation catalyst at an elevated temperature to afford a slurry containing solid quinacridone and the compound, represented by formula II and dissolved in a solvent. (4) The quinacridone, the catalyst and other impurities are then separated from the solvent. (5) The 2-anilinoacridone represented by formula II is further separated from the solvent.

Title: Surface treatment of substrate for hard disk
Inventor: MIHASHI HIROYUKI
IPC: C23C18/16
Filed: 1990-05-18
Abstract: PURPOSE:To enhance the adhesive strength of an Ni-P plating film to a substrate and to obtain the substrate for hard disks which can improve surface characteristics by immersing the substrate essentially consisting of aluminum into a zincate liquid, then immersing the substrate into an acetic acid soln. and subjecting the substrate to Ni-P plating. CONSTITUTION:The zincate liquid is first filled into a bath tank consisting of enamel, ceramics or metals, etc., and the disk-shaped aluminum substrate 1 is immersed into this zincate liquid. Consequently, the surface of the aluminum substrate 1 is substd. with Zn and a Zn layer 2 is formed on the surface of the substrate 1. The surface of the Zn layer 2 of this time is zinc hydroxide. The substrate 1 is then immersed into the acetic acid soln. Consequently, the zinc hydroxide layer 2a formed on the surface of the Zn layer 2 is removed. The zinc hydroxide does no longer exist on the surface of the Zn layer 2 at all and only the Zn layer 2 having the excellent surface characteristics is exposed. The substrate 1 is then immersed into an Ni-P plating bath and is subjected to electroless plating. Consequently, the Ni-P plating precipitates on the Zn layer 2 and the Ni-P plating film 3 is formed. The film 3 formed at this time is directly formed on the Zn layer 2 and, therefore, the peeling of the film 3 from the Zn layer 2 does not arise.
