DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) A coating remover for cleaning substrate surfaces comprises a halogenated hydrocarbon solvent, a F-contg. alc., and an org. acid. Thus, 1,1,2-trichloro-1,2,2-trifluoroethane [76-13-1], methylene chloride [75-09-2], 2,2,3,3-tetrafluoropropanol [76-37-9], and dodecylbenzenesulfonic acid [27176-87-0] were mixed in a wt. ratio of :. An iron plate coated with an alkyd resin paint was immersed into the compn. at room temp., and the coating was completely peeled off in 50 s.

DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 4, 17, 25 Of 6 H(CF2)nCH2OR (I, R = H, SiMe3; n = 1,3, 5), 11 RCO2CH2(CF2)nH (II, R = Me, CCl3, Ph, CF3; n = 1,3, 5), 8 F2CH(CF2)nCH2O2CCO2CH2(CF2)n1CF2H (III, n and n1 = 1, 3, 5), 3 IV (n = 1, 3, 5), and 3 F2CH(CF2)nCH2OSO2CH2(CF2)nCF2H (V, n = 1, 3, 5), I (R = H; n = 1) [76-37-9], II (R = Me; n = 1) [681-58-3], and II (R = CF3; n = 1) (VI) [107551-72-4] were the most effective fumigants against the granary pest Calandra oryzae, having LD values smaller than that of the dichloroethane std. VI was also an effective contact insecticide. The most active nematocides were III (n = 1; n1 = 3) [866-11-5] and IV (n = 1) [803-82-7]; their effectiveness approached that of the heterophos std. I-V showed extremely low mammal toxicity, most of them having LD50 values for mice >1000 mg/kg. Synthesis was indicated. .
