Lustrous pigments

Lustrous pigments. Ambrosius, Klaus; Esselborn, Reiner (Merck Patent G.m.b.H. , Fed.Chemicals with cas numbers 1314-23-4 and 13463-67-7 also play role. Rep. Ger.). Ger. Offen. DE 3221045 A1 8 Dec 1983, 11 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09C001-00; A61K007-00; C09D005-36; C08K009-02. APPLICATION: DE 82-3221045 4 Jun 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Pearlescent pigments with good gloss and tinctorial strength are prepd. by coating mica platelets with TiO2 contg. 1-10% ZrO2. Thus, adding 900 mL soln. contg. 150 g/L TiCl4 and 2.2 g/L ZrOCl2×8H2O slowly to a suspension of 60 g K mica (particle size 10-70 m) in 2 L H2O acidified to pH 2.6 and stirred at 75°, together with sufficient NaOH to maintain a pH of 2.6, filtering, drying the solid at 120°, and calcining at 800° for 45 min gave a blue pigment with high luster and tinctorial strength. .

Methanol synthesis catalyst

Methanol synthesis catalyst. (Tokuyama Soda Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58114730 A2 8 Jul 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B01J023-10; C07C029-15; C07C031-04. APPLICATION: JP 81-209830 28 Dec 1981. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Catalysts for the synthesis of MeOH were prepd. by heating ZrO2 and CeO2 in the absence of air. Thus, 2.5 wt. % NH4OH was added to a soln. of 100 g ZrO(NO3)2.2H2O and 7.0 g Ce(NO3)3.6H2O in H2O to pH 7-8, the ppt. filtered and dried at 110° and heated at 450° to give a glassy gel contg. 67-56-1 and 1314-23-4 are cas registry numbers of chemicals which are used as reagents here. 5.7% CeO2, which was crushed to 10-28 mesh. A 2:1:1 mixt. of H, CO, and Ar was passed over the catalysts at 200° to give 0.30% MeOH (theor. equil. yield: 0.60%) and MeOH to hydrocarbon ratio of 480, vs. 0.005% and 0.32, resp., with ZrO2 only. .
