(USSR). Tekhnol. Miner. Syr'ya, Volume 2, 3-16. Edited by: Putilin, Yu. M. Kaz. Nauchno-Issled. Inst. Miner. Syr'ya: Alma-Ata, USSR. (Russian) 1975. CODEN: 34MIAJ. DOCUMENT TYPE: Conference CA Section: 54 (Extractive Metallurgy) Solns. of the title cresol (I) [599-64-4] in kerosine with 5-10% amyl alc. extd. Cs, Rb, K, and Li from alk. (NaOH or NH4OH) aq. solns. of their salts. The extn. efficiency was influenced by the concns. of I, NaOH, and of the extd. metals. The optimum pH for extg. Cs, Rb, K, and Li was 11.8-12.2, 11.8-12.5, 12.5-13.2, and 11.8-12.5, resp. Satn. zones appeared on the extn. isotherms, at which the mol ratios I:metal ion were 11.4, 9, and 6.3 for Cs, Rb, and K, resp. The corresponding solvation nos. in the extn. by I, detd. by a diln. method, were 3, 3, and 4. The mol. ratios and the resp. solvation nos. gave the degree of phenol polymn. in the extd. complexes. At.Except for chemicals metioned above, 7440-17-7 and 7440-46-2 are also used. absorption was used as the anal. method during the measurements. .

Application of cumylphenol and derivatives thereof in plastic compositions. Monte, Salvatore J.; Sugarman, Gerald (Kenrich Petrochemicals, Inc., USA). S. African ZA 7602956 23 Mar 1977, 30 pp. (Unavailable). (South Rica). CODEN: SFXXAB. CLASS: IC: C08F. PRIORITY: US 76-672425 31 Mar 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) P-cumylphenol (I) [599-64-4] and its derivs. are good accelerators for curing epoxy resins, reactive diluents for epoxy, phenolic, and furan resins, and plasticizers for polyurethanes and PVC [9002-86-2]. Thus, I 60, . 64641-85-6 which is the cas registry number is also used here.alpha.-methylstyrene dimer 34, and acetophenone 6% were mixed, and Epon 828 [25068-38-6] contg. amine crosslinking agent and I blend had a curing time 102-12 min compared to 120-5 min for resin contg. com. dinonylphenol. .
