Thermal recording materials

Thermal recording materials. Sakai, Hisashi; Ono, Mitsuo (Ricoh Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 61262185 A2 20 Nov 1986 Showa, 7 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: B41M005-18. APPLICATION: JP 85-105255 17 May 1985. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Thermal recording materials utilizing the color-forming reaction between leuco dyes and color developers contain p-dicyclohexylbenzne (I) as a sensitizer. The materials show excellent heat sensitivity and image stability. Thus, 3'-(N-methyl-N-cyclohexylamino)-7'-anilinofluoran 20, 10% aq. poly(vinyl alc.) 20, and water 60 parts were mixed to obtain a dispersion (A; av. particle size ￡2 m). Sep., Bisphenol A 10, I 10, CaCO3 10, 10% poly(vinyl alc.) 30, and water 40 parts were mixed to obtain a dispersion (B; av. particle size ￡2 m). Then, A 1, B 6, and 10% poly(vinyl alc.) 1 part were mixed, coated on a paper (52 g/m2) at 5 g/m2 (dry basis), and calendered to obtain a material with smoothness ~800 s. The material was applied to a thermal facsimile device at 20° and 0°, showing color d. 1.31 and 1.01, resp., vs. 1.23 and 0.65, resp., for a control using stearamide in place of I.Except for chemicals metioned above, 1087-02-1 is also used. .

Phenylcyclohexane formed by cracking dicyclohexylbenzene

Phenylcyclohexane formed by cracking dicyclohexylbenzene. Chung, Tae H.; Patel, Chandrakant A.; Sayigh, Adnan A. R. (Upjohn Co., USA). U.S. US 3984490 5 Oct 1976, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07E015-00. NCL: 260668000R. APPLICATION: US 75-575607 8 May 1975. DOCUMENT TYPE: Patent CA Section: 25 (Noncondensed Aromatic Compounds) Dicyclohexylbenzene (I), by-product in the hydrodimerization of benzene to give phenycyclohexane (II), was converted into II by heating at 195-240.degree. with 1.5-5 parts (wt) benzene in the presence of an acid clay or zeolite catalyst. The period of heating is controlled so that cracking of the product II is not appreciable. Thus, a mixt. obtained by hydrodimerization of benzene and distn. (17.4 g contg. 52.3% m- and 44.8% p-I) was mixed with 17.4 g benzene and stirred for 2 hr at 200-22.degree.In this experiment, several chemicals are used like 71-43-2 and 1087-02-1 under N with 3.5 g calcined bentonite clay to give II with 98% selectivity and 72.1% conversion of I. .
