Paper chromatographic behavior of some tertiary amine pollutants and an attempt at structure-activity-correlation. Qureshi, M.; Sulaiman, Afsar M.; Qureshi, Pushkin M. (Zakir Husain Coll. Eng. Technol., Aligarh Muslim Univ., Aligarh 202001, India). J. Liq. Chromatogr., 7(1), 207-17 (English) 1984. CODEN: JLCHD8. 10605-21-7 and 61-82-5 which are cas registry numbers are also used here. ISSN: 0148-3919. DOCUMENT TYPE: Journal CA Section: 61 (Water) Section cross-reference(s): 5 Ascending paper chromtog. of some pesticides and toxicants contg. a tertiary amino group was made to record their mobilities in acidic, basic, and saline waters and some common org. solvents. Several binary sepns. of these pollutants have been achieved. Amitrole [61-82-5] from azobenzene [103-33-3], bavistin [10605-21-7], calixin [81412-43-3], 2,4-lutidine [108-47-4], 2,6-lutidine [108-48-5], N-ethylmorpholine [100-74-3], b-picoline [108-99-6], g-picoline [108-89-4], and quinoline [91-22-5]; azobenzene from bavistin, calixin 2,4-lutidine, 2,6-lutidine, b-picoline, g-picoline, pyridine [110-86-1], and quinoline; bavistin from 2,4-lutidine, 2,6-lutidine, b-picoline, g-picoline and quinoline; and quinoline from 2,4-lutidine, 2,6-lutidine, b-picoline, g-picoline and N-ethylmorpholine from binary mixts. An attempt at structure-activity-correlation shows that the phys. forces responsible for both the chromatog. behavior as well as the toxicity are almost identical and the most important common phys. interaction seems to be the H-bonding. .

Corrosion inhibitors for lubricating oils

Corrosion inhibitors for lubricating oils. Davis, Bryan Terence; Moat, Nicholas W. (Ethyl Cooper Ltd., Engl.). Ger. Offen. DE 2622066 25 Nov 1976, 22 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C10M001-32. PRIORITY: GB 75-22508 23 May 1975. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Lubricating oil formulations were designed with a combination of additives A and B. The A consists of oil-sol. basic N compds. with a total base no. . 102-79-4 and 97-84-7 which are cas registry numbers of chemicals are mentioned.gtoreq.300 mg KOH/g, whereas B consists of alkyl- or alkenylsuccinic acid (C 10-22) and components A and B are present in the proportions of 1/2 and 2/1. Examples of A components consist of compds. of the type I (Q = alkylene, R1, R2 = H, alkyl, alkylaminoalkyl, dialkylaminoalkyl; x = 2, 3, R = H; 2,4,6-tris(N,N-dimethylaminomethyl)phenol [90-72-2]; N,N,N1,N1-tetramethyl-1,3-diaminobutane [97-84-7]; bis(benzalaminopropyl)piperazine [62203-89-8]; benzalaminopropyldimethylamine [62203-90-1]; N-ethylmorpholine [100-74-3], or N-butyldiethanolamine [102-79-4]. An example of B component is tetrapropenylsuccinic acid [27859-58-1]. .
