Lack of mutagenicity to S

Lack of mutagenicity to S. typhimurium of neopentyl bromide and pentaerythrityl tetrachloride: relation to chemical structure. Ashby, John; Callander, R. D.; Gilman, D. (Cent. Toxicol. Lab., Imp. Chem. Ind. PLC, Cheshire, UK). Mutat. Res., 140(2-3), 71-4 (English) 1984. CODEN: MUREAV. ISSN: 0027-5107. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Neopentyl bromide [630-17-1] and pentaerythrityl tetrachloride [3228-99-7] were nonmutagenic to 7 strains of Salmonella typhimurium. These inactivities are reflected in the inability of either compd. to produce a color reaction in the chem. alkylation test of J. Epstein et al. (1955). Apparently, the lack of biol. reactivity of these 2 alkyl halides is due to steric crowding of the halogen group. These findings are significant within the context of the potent mutagenicity of monohaloalkanes in general. The similarity between the odor of pentaerythrityl tetrachloride and camphor is discussed.

Dyeable polymer composition adapted for fibers, films, and molded articles

Dyeable polymer composition adapted for fibers, films, and molded articles. Semeghini, Gianluigi; Righi-Elvino de Fornasari, Gianpietro; Parrini, Paolo (Montedison S.p.A., Italy). Ital. IT 927516 1 Sep 1972, 20 pp. (Italian). (Italy). CODEN: ITXXAX. CLASS: IC: C08F. APPLICATION: IT 19710618. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Tetrakis(p-toluenesulfonamidomethyl)methane (I) [24935-69-1] was prepd. and added to polyester and rubber fibers compns. to give improved dyeability without loss of phys. properties. A mixt. of 105 g SOCl2 and 27.4 g tetramethylolmethane [115-77-5] contg. 10 cm3 pyridine was heated at 65-70.degree. to give tetrakis(chloromethyl)methane (II) [3228-99-7]. II was treated with p-toluenesulfonamide [70-55-3] 7 hr at 220-30.degree. to give I m. 249-51.degree.. I (0.5-4.0%) was added to 200 g poly(ethylene terephthalate) and the mixt. was drawn into fibers which were dyed with Rosa Samaron FBL to a high color intensity. The fibers had tenacity 3.5-3.8 g/dtex, elongation at break 42-7%, and fastness to light 7-8, compared with 3.Except for chemicals metioned above, 70-55-3 and 7719-09-7 are also used.9, 48, and 6 when no I was added. .
