Chromium-nickel stainless steel vessel corrosion-resistant in aqueous heteropoly acids

Chromium-nickel stainless steel vessel corrosion-resistant in aqueous heteropoly acids. (Tokuyama Soda Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58197257 A2 16 Nov 1983 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C22C038-44. ICA: B01J019-02. APPLICATION: JP 82-79130 13 May 1982. DOCUMENT TYPE: Patent CA Section: 55 (Ferrous Metals and Alloys) To avoid H embrittlement in olefin hydrogenation with a heteropoly acid catalyst, the vessel is lined with a Cr-Ni stainless steel contg. Ni 2-7, Cr 19-27, C ￡0.05, Mo ￡3, and Cu ￡3% with austenitic welds contg. Ni 9-16, Cr 16-21, C ￡0.03, and Mo ￡3%. It is unnecessary to line with Au, Pt, or Ag. Thus, a steel [88833-98-1] plate contg. C 0.03, Si 0.61, Mn 0.72, Cr 24, Ni 4.88, Mo 1.5, and Cu 0.9% and steel [88833-99-2] contg. C 0.014, Si 0.48, Mn 1.52, Cr 18.28, Ni 10.12% were overlay welded twice with a 2.6 mm diam. austenitic stainless steel [88834-00-8] rod contg. C 0.009, Si 0.29, Mn 1.71, Cr 20.24, Ni 10.04, and Mo 0.07% and cut. The assembly was hung in a 1.5 L vessel lined with Ag, and aq. 0.3% phosphomolybdic acid [1343-93-7] 3 and C3H6 0.2 kg/h-L were fed at 300° and 200 kg/cm2 for 3950 h. The Vickers hardness was 150-170 as welded or 230-290 after wire brush polishing, and no stress corrosion cracking was obsd., compared to cracking for all after 300 h when ground to give a hardness of 320-360.

The polymerization of hexachlorocyclotriphosphazene by molybdenum phosphate and tungsten phosphate. Kajiwara, M.; Saito, H. (Fac. Eng., Nagoya Univ., Nagoya 464, Japan). Angew. Makromol. Chem., 132, 197-201 (English) 1985. CODEN: ANMCBO. ISSN: 0003-3146. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) (NPCl2)3 homopolymer [25231-98-5] was obtained by bulk polymn. in the presence of H3PMo12O40 [12026-57-2] or H7PW12O40 [1343-93-7]; linear polymer was predominantly formed when H7PW12O40 was used.
