Nigrosine dyes: Nigrosine dyes. Maekawa, Yoshihiro; Matsuura, Masatoshi (Orient Chemical Industries, Ltd., Japan). Japan. Kokai JP 52135336 12 Nov 1977 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09B057-00. APPLICATION: JP 76-53590 10 May 1976. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Nigrosine dyes of high purity were obtained by treating reaction mixts. with water, NaOH, or satd. aq. NaCl optionally contg. NaOH. For example, aniline [62-53-3], 30% HCl, FeCl2, and Fe powder were heated at 120-5° to expel water, rapidly heated to 180°, treated with nitrobenzene [98-95-3] over 4-5 h, and heated at 180-5° for 3 h, and the reaction mixt. was stirred with equal amt. of water for 2 h. The aniline layer (lower layer) was sepd. and concd. in vacuo to give Nigrosine Spirit Sol. [11099-03-9] with ash content 1.5-2%, compared with 5% for control prepd. by conventional method. Nigrosine Base [8005-02-5] with ash content ￡1.5% was also prepd.

Polymerization of vinyl monomers: Polymerization of vinyl monomers. (Shin-Etsu Chemical Industry Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59170102 A2 26 Sep 1984 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08F002-00. APPLICATION: JP 83-44878 17 Mar 1983. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) The wall of a polymn. reactor is coated with dyes and P oxide compds. to prevent scale formation. Thus, water 40,000, 1,3-butadiene 10,000, styrene 10,000, acrylic acid 400, Na lauryl sulfate 600, tert-C12H25SH 500, and K2S2O8 100 g were stirred 8 h at 60° in a reactor coated with C.I. Solvent Black 7 [8005-02-5] and H3PO4 with scale formation 8 g/m2, compared with 1200 in a reactor without coatings.
