2-Hydroxyalkyl esters

2-Hydroxyalkyl esters. Steele, Roger B.; Katzakian, Arthur, Jr. (Aerojet-General Corp., USA). 17200-46-3 and 1675-54-3 are also occured in this study. U.S. US 4017429 12 Apr 1977, 11 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08F002-00. NCL: 260002000EP. APPLICATION: US 70-4056 19 Jan 1970. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 78 Active Cr catalysts were prepd. for reaction of oxiranes or oxirane polymers with alkanoic acids and for use as crosslinking catalysts. Thus, Na 2-ethylhexanoate [19766-89-3] was treated with chromium nitrate [13548-38-4] to give an inactive, aquated chromium tris(2-ethylhexanoate) (I) [3444-17-5]. A stock soln. of 5.0 g I and 2.5 g 2-ethylhexanoic acid (II) [149-57-5] was prepd. and heated at 140.degree. for 0 (control) to 6 h to deaquate the complex to give an active catalyst species (A) having 90% open coordination sites. The A catalyzed the reaction of II with 1,2-butylene oxide [106-88-7] to 100% completeness in 1 h at 22.degree., compared to only 10.6% completeness after 72 h for the aquated complex. .

Sulfate zinc plating bath

Sulfate zinc plating bath. Nikitina, O. A.; Chernikova, E. A.; Vyacheslavov, P. M. (Kuibyshev Aviation Institute, USSR). U.S.S.R. SU 1076499 A1 29 Feb 1984 From: Otkrytiya, Izobret., Prom. Obraztsy, Tovarnye Znaki 1984, (8), 87. (Russian). (Union of Soviet Socialist Republics). CODEN: URXXAF. CLASS: IC: C25D003-22. APPLICATION: SU 81-3301400 23 Mar 1981. DOCUMENT TYPE: Patent CA Section: 72 (Electrochemistry) The throwing powder and leveling capacity of the bath and plasticity of Zn electroplates are increased by adding 0.5-1.0 g/L water-sol. metal nitrate consisting of Cr nitrate, Tl nitrate, Ni nitrate, or Ce nitrate to the bath contg. 16901-76-1 and 13548-38-4 are just another two chemicals used in this study. ZnSO4 230-250, Na2SO4 70-80, and Al2(SO4)3 25-30 g/L. .
