Metabolism of 2-isopropylphenyl N-methylcarbamate (Mipcin, MIPC) in rice plants and its degradation in soils

Metabolism of 2-isopropylphenyl N-methylcarbamate (Mipcin, MIPC) in rice plants and its degradation in soils. Ogawa, Kunihiko; Tsuda, Masataka; Yamauchi, Fumio; Yamaguchi, Isamu; Misato, Tomomasa (Inst. Phys. Chem. Res., Wako, Japan). Nippon Noyaku Gakkaishi, 2(1), 51-7 (English) 1977. CODEN: NNGADV. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) Studies were conducted on absorption, translocation, and metab. by rice plants and degrdn. in soils of 14C-labeled 2-isopropylphenyl N-methylcarbamate (Mipcin)(I) [2631-40-5] labeled at the 2-position of the iso-Pr radical. The label was readily absorbed from roots and leaves, translocated to upper parts, and lost from leaves. Major metabolites in straw were 2-(1-hydroxyisopropyl)phenyl N-methylcarbamate [63986-19-6] and 2-isopropylphenyl N-hydroxymethylcarbamate [17863-56-8]. Conjugated 2-isopropylphenyl carbamate (II) was predominant in grains. Degrdn. 2631-40-5 which is the cas registry number of one of substances is just one of reagents here. of I in soil was more rapid under upland than flooded conditions, yielding II and 2-isopropylphenol [88-69-7], resp., as major products. Most of the metabolites were less inhibitory to cholinesterase than I. .

CLASS: IC: A01N031-08; A01N057-00; A01N025-02; A01N025-00; C11D003-48; C11D009-50. APPLICATION: DE 84-3414928 19 Apr 1984. PRIORITY: GB 83-11081 23 Apr 1983. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 5, 25 Disinfectants contain: phenol [108-95-2] 0.5, 32 diisopropylphenols (<20% 2.5-diisopropylphenol) 20-100, and mono-, tri-, or higher isopropylphenols 0-80% by wt. the disinfectant may be black or white emulsions or clear solns., and may contain pine tar oil. Thus, 752 parts phenol and 15 parts fullers' earth, under N, were heated to 140° and propylene [115-07-1] gas was added at 4 L/min for 4.25 h. The mixt. was cooled under N and the catalyst was filtered to give a liq. contg.: phenol 3.03, 2-isopropylphenol [88-69-7] 17.3, 3-isopropylphenol [618-45-1] 0.63, 4-isopropylphenol [99-89-8] 3.52, 2,6-diisopropylphenol [2078-54-8] 17.8, 2,4-diisopropylphenol [2934-05-6] 16.2, 2,5-diisopropylphenol [35946-91-9] 4.18, 3,5-diisopropylphenol [26886-05-5] 0.55, 2,4,6-triisopropylpenol [2934-07-8] 30.9, and 2,4,5-triisopropylphenol [55154-67-1] 5.54%. A disinfectant contained the isopropylphenol mixt. 2, pine tar oil 4, 30% sapond. castor oil 20, and H2O 74%.
