U.S. US 4420340 A 13 Dec 1983, 6 pp. Cont.-in-part of U.S. Ser. No. 343,550, abandoned. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C09D005-02. NCL: 106288000B. APPLICATION: US 82-440573 10 Nov 1982. PRIORITY: US 82-343550 28 Jan 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Pigments for latex vehicles having good color retention under fading conditions comprised manganomanganic oxide (Mn3O4) (I) [1317-35-7]. Thus, an emulsion-type paint compn. was prepd. by mixing water 59, 20% aq. polyacrylate thickener 25. 1317-35-7 is the cas registry number of certain chemical which is used as reagents here.0, dispersant 17.6, Triton CF10 17.6, ethylene glycol 28.0, defoamer 5.7, ZnO 12.0, CaCO3 53.0, biocide 2.1, and fumed I 151 g. Then acrylic latex 667.0, NH4OH 7.0, and coalescing agent 5.7 g were added. Test panels were coated with the resulting paint and exposed to a Fadeometer test. After 1000 h, only a slight degree of fading took place. .

CLASS: IC: C07C001-04; B01J029-06. APPLICATION: JP 82-73456 4 May 1982. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Hydrocarbon mixts. were prepd. by catalytic hydrogenation of CO over Ru on cryst. zeolite-Mn oxide. Thus, a mixt. of 20 g of H-type zeolite and 80.8 g Mn(NO3)2 was adjusted to pH 9.0 with 3N NH4OH and resulting gel was dried at 130° and calcined at 500° to give 1:1 zeolite-Mn oxide, which in aq. RuCl3 was heated at 130° to give a catalyst contg.Several substances with their cas registry numbers 1317-35-7 and 630-08-0 may be metioned in this study. 1 wt.% Ru. H-CO (1:1 M) was introduced to the above catalyst (previously hydrogenated 5 h at 400°) at 290°/40 kg/cm2 gage to give hydrocarbon mixt. of 2 wt.% C2, 12 wt.% C2-4, and 86 wt.% C 35 gasoline contg. 36 wt.% aroms. with 86% conversion of CO, vs. 24, 26, 50 wt.% and 69%, resp. without Mn oxide. .
