Anionic bituminous emulsions: Anionic bituminous emulsions. Zdybak, Walter T. (Georgia-Pacific Corp., USA). U.S. US 4427449 A 24 Jan 1984, 6 pp. (English). (United States of America). 69812-51-7 and 8061-51-6 are cas registry numbers. These chemicals are also mentioned in this article. CODEN: USXXAM. CLASS: IC: C08L095-00; C09D003-24. NCL: 106277000. APPLICATION: US 82-387512 11 Jun 1982. DOCUMENT TYPE: Patent CA Section: 58 (Cement, Concrete, and Related Building Materials) Emulsifying agents for anionic asphalt emulsions for coating of aggregates are prepd. by converting lignosulfonate-contg. fermented spent sulfite liquors to the Na salt and reacting with org. sulfonyl compds. Thus, a concd. fermented Ca-base spent liquor with 200 g dry solids was treated with 50% NaOH soln. to give Na-base liqnosulfonate with pH 9, dild., with 500 mL water contg. 200 mL toluene, treated successively with ethyltriphenylphosphonium iodide [4736-60-1] 0.2, toluenesulfonyl chloride 27, and 50% NaOH 11.2 g, stirred 3 days during which the pH dropped to 7.1, and the toluene was stripped. The lignosulfonate reaction product had a phenolic OH content of 0.86% based on the original liquor. Asphalt emulsified with 1.15% of the product gave excellent coatings with respect to color and uniformity on sand-clay mixts. .

Crystal and molecular structures and technological properties of epoxy hardening accelerators from ethyltriphenylphosphonium iodide: Crystal and molecular structures and technological properties of epoxy hardening accelerators from ethyltriphenylphosphonium iodide. Cheban, Yu. M.; Rotaru, V. K.; Simonov, Yu. A.; Bel'skii, V. K. (USSR). Izv. Akad. Nauk Mold.Several reagents with their cas registry numbers 9003-35-4 and 4736-60-1 are used here. SSR, Ser. Fiz.-Tekh. Mat. Nauk, (1), 22-7 (Russian) 1986. CODEN: IZFMBL. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 35 Structural data for EtPh3P+.I- (I) [4736-60-1] catalyst for crosslinking epoxy resins with novolak phenol-formaldehyde copolymer [9003-35-4] indicated that the I atom located in the outer sphere of the phosphonium cation may play an essential role in the initiation mechanism for the crosslinking. The effectiveness of I in initiating the crosslinking over the temp. range 100-180° decreased with decreasing temp. At 0.01 part I in the compn., the gel time was 15 min at 180° and 90 min at 130°. Atom coordinates, interat. distances, and bond angles are given for I. .
