Isolation of 3-N-cyclohexylaminophenol by distillation. Nakatsuka, Masakatsu; Otsuji, Atsuo; Hasegawa, Kiyoharu; Takagi, Masatoshi; Yamaguchi, Teruhiro (Mitsui Toatsu Chemicals, Inc., Japan). Jpn. Kokai Tokkyo Koho JP 03240758 A2 28 Oct 1991 Heisei, 3 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: C07C215-76. ICS: C07C213-02; C07C213-10. APPLICATION: JP 90-36179 19 Feb 1990. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 41 The title compd. (I), useful as an intermediate for org. compds. and dyes, is prepd. from cyclohexylamine (II) and resorcinol (III), followed by isolation by distn. of the reaction mixts. II was treated with III at 160-170° for 12 h and distd. 108-91-8 and 5269-05-6 which are cas registry numbers of substances are two of reagents here. at 9 mmHg to give 85% I, vs. 20%, when extd. with MePh. .

3-Aminophenol derivatives as intermediates for fluorans and their preparation. Nakatsuka, Masakatsu; Otsuji, Atsuo; Hasegawa, Kiyoharu; Takagi, Masatoshi; Yamaguchi, Teruhiro (Mitsui Toatsu Chemicals, Inc.In this study， 5269-05-6 and 953-91-3 are also used., Japan). Jpn. Kokai Tokkyo Koho JP 04001160 A2 6 Jan 1992 Heisei, 5 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: C07C215-76. ICS: C07C213-08. APPLICATION: JP 90-101682 19 Apr 1990. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 25 3-Aminophenol derivs. I (R1 = Pr, Bu, isobutyl), intermediates for fluoran color former used in recording materials, are prepd. by (A) treating 3-N-cyclohexylaminophenol (II) with R1X1 (X1 = halo) or R1OTs or (B) treating 3-HOC6H4NHR1 with monohalocyclohexanes or cyclohexyl tosylate. Thus, treating II with PrBr in methyl Cellosolve at 90° for 15 h gave 98% I (R1 = Pr). .
