All Rights Reserved. Oxirane, methyl-, polymer with oxirane, monobutyl ether; tolerance exemption. (Environmental Protection Agency EPA; Office of Pesticide Programs, Environmental Protection Agency, Washington, DC 204600-0001, USA). Federal Register, 71(143), 42285-42288, 26 Jul 2006 (English) 2006 Superintendent of Documents. CODEN: FEREAC. ISSN: 0097-6326. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Section cross-reference(s): 4, 5 This regulation establishes an exemption from the requirement of a tolerance for residues of oxirane, methyl-, polymer with oxirane, monobutyl ether; when used as an inert ingredient in a pesticide chem. formulation. BASF Corporation, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA) requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a max. permissible level for residues of oxirane, methyl-, polymer with oxirane, monobutyl ether.

Dem. Rep.). Ger. (East) DD 212042 A1 1 Aug 1984, 7 pp. (German). (German Democratic Republic). CODEN: GEXXA8. CLASS: IC: C08G018-28; C07C091-00. APPLICATION: DD 81-235129 26 Nov 1981. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 23 Alkanolamines useful in the prepn. of polyols are prepd. by the multistage or continuous reaction of epoxides with NH3 in polar solvents followed by fractionation. Thus, adding 1 kg NH3 and then 500 g propylene oxide [75-56-9] to 3 kg H2O at 85°, stripping excess H2O and NH3 after reaction was complete, and distn. at 110-120°/0.65-1 kPa gave isopropanolamine [78-96-6] of 99.4% purity.
