Reactions of antioxidants in foods: Reactions of antioxidants in foods. Warner, C. R.; Brumley, W.Several substances are used for example 25013-16-5 and 10396-80-2 which are their cas registry numbers. C.; Daniels, D. H.; Joe, F. L., Jr.; Fazio, T. (Food Drug Adm., Washington, DC 20204, USA). Food Chem. Toxicol., 24(10-11), 1015-19 (English) 1986. CODEN: FCTOD7. ISSN: 0278-6915. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) The chem. transformations of BHT [128-37-0] and BHA [25013-16-5] in the deep-fat frying of potatoes were studied. Approx. 80% of the BHT and its assocd. decompn. products was lost from the lard after six batches of french fries. This may have been due to steam distn. caused by the water boiled out of the potatoes. In contrast, 80% of the radiocarbon introduced as radiolabeled BHA was retained by the frying medium even after 12 batches of french fries. The concn. of intact BHA decreased to undetectable levels after four batches. Because of the complexity of the products formed in the heated fats, studies were undertaken on the thermolysis of a hydroperoxy deriv. of BHT, 2,6-di-tert-butyl-4-hydroperoxy-4-methylcyclohexa-2,5-dienone [6485-57-0]. The product mixt., which was identified by mass spectrometry and gas chromatog.-mass spectrometry, included BHT, 2,6-di-tert-butyl-4-hydroxy-4-methylcyclohexa-2,5-dienone [10396-80-2] and 3,5-di-tert-butyl-4-hydroxybenzaldehyde [1620-98-0]. Elemental compns. of other unidentified products were detd. by high-resoln. mass spectrometry. .

M. (Mobil Oil Corp. , USA). U.S. 88164-27-6 and 88183-15-7 are cas registry numbers. These chemicals are also mentioned in this article. US 4405470 A 20 Sep 1983, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C10M001-48. NCL: 252032700E. APPLICATION: US 82-341718 22 Jan 1982. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 25 Hindered a-amino-4-hydroxybenzyl phosphorodithioates (I) (R,R1,R2,R3,R4, and R5 = C1-30 hydrocarbyl) are useful as antioxidant and antiwear additives for lubricating oils. Thus, 150 mL PhMe contg. 0.2 mol octadecylamine [124-30-1] and 0.2 mol 3,5-di-tert-butyl-4-hydroxybenzaldehyde [1620-98-0] was refluxed with a mild N purge in a flask equipped with a Dean-Stark trap until the theor. amt. of H2O was collected. Then, 0.2 mol O,O'-bis(4-methyl-2-pentyl)phosphorodithioic acid [6028-47-3] was added rapidly to the cooled product, and the mixt. was heated at 80° for 7 h under N. Purifn. of the product gave I (R = R1 = tert-Bu, R2 = H, R3 = R4 = 4-methyl-2-pentyl, R5 = octadecyl) [88164-28-7]. .
