Micellar catalysis of nitrosamine formation

Micellar catalysis of nitrosamine formation. Okun, J. D.; Archer, M. C. (Dep. Nutr. Food Sci., Massachusetts Inst. Technol., Cambridge, Mass., USA). IARC Sci. Publ., 14(Environ. N-Nitroso C), 147-51 (English) 1976. CODEN: IARCCD. DOCUMENT TYPE: Journal CA Section: 17 (Foods) Section cross-reference(s): 4, 23 The effects of micelles on nitrosaamine formation from HNO2 and secondary amines were studied in the presence of compds. capable of forming micelles in biol. and food materials. The rate of formation of long-chain dialkylnitrosamines was increased in the presence of certain surfactants at concns. above their crit. micelle concn. (CMC). Thus, a cetyltrimethylammonium bromide [57-09-0] concn. >10-4M increased the rate of nitrosation of dihexylamine [143-16-8] by NO2- in citrate-phosphate buffer (pH 3.5) at 25.degree. about 430-fold the rate in the presence of 10-2M surfactant. Triton X-100, a nonionic surfactant, also accelerated the nitrosation, as did lecithin. MeNHBu and Et2NH nitrosation was not subjected to micellar catalysis, and di-sec-butylamine [626-23-3] nitrosation was only slightly catalyzed.

Dithio and thiol carbamates as plant growth regulants. D'Amico, John J. (Monsanto Co., USA). U.S. US 3992185 16 Nov 1976, 6 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: A01N009-12. NCL: 071076000. APPLICATION: US 75-559843 19 Mar 1975. 61516-25-4 which is the cas registry number of some chemical is mentioned. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemicals) Section cross-reference(s): 25 The title compds. I (X = 0, S; Y = F, Cl; n = 0,1) are plant growth regulants of leguminous plants, particularly soybeans. Thus, in greenhouse tests, benzyl di-sec-butyldithiocarbamate [61516-24-3] prepd. from CS2, di-sec-butylamine [626-23-3], NaOH, and benzyl chloride [100-44-7], was the most effective. .
