Partition coefficients of some industrial aliphatic hydrocarbons (C5-C7) in blood and human tissues

Partition coefficients of some industrial aliphatic hydrocarbons (C5-C7) in blood and human tissues. Perbellini, L.; Brugnone, F.; Caretta, D.; Maranelli, G. (Inst. Occup. Med., Univ. Verona, Verona, Italy). Br. J. Ind. Med., 42(3), 162-7 (English) 1985. CODEN: BJIMAG. ISSN: 0007-1072. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Section cross-reference(s): 59 Saline/air, blood/air, olive oil/air, and tissue (lung, kidney, liver, brain, muscle, heart, and fat)/air partition coeffs. were detd. for 9 aliph. hydrocarbons: n-pentane [109-66-0], 2,2-dimethylbutane [75-83-2], 3-methylpentane [96-14-0], 2-methylpentane [107-83-5], methylcyclopentane [96-37-7], n-hexane [110-54-3], cyclohexane [110-82-7], 3-methylhexane [589-34-4], and n-heptane [142-82-5]. Blood/air partition coeffs. were between 0.38 (n-pentane) and 1.9 (n-heptane). The value of the tissue/air partition coeffs. rose from n-pentane to n-heptane; the tissue/air partition coeffs. were correlated with the blood/air partition coeffs. The mean soly. of the 9 aliph. hydrocarbons in the different tissues was higher than in blood by the factors: lung 1.4 (range 1.2-2.1), heart 3.9 (0.5-4.5), liver (5.6 (5.5-13.5), kidney 5.2 (1.6-5.8), brain 6.5 (5.8-10.7), muscle 7.6 (1.8-8.8), and fat 205 (104-254). The blood/air and olive oil/air partition coeffs. were correlated with the b.p. and the mol. wts. of the aliph. hydrocarbons.

Amino resin foaming compositions

Amino resin foaming compositions. (Nagoya Yukagaku Kogyo K. K., Japan). Jpn. Kokai Tokkyo Koho JP 58149926 A2 6 Sep 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08J009-14; C08L061-20. APPLICATION: JP 82-33687 2 Mar 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Lightwt., uniform, closed-cell foams useful as sound and thermal insulation are manufd. from mixts. of amino resins, optionally resorcinol compds. or polymers, and thermoplastic resin-encapsulated volatile blowing agents. Thus, HCHO-urea initial condensate [9011-05-6] 100, neohexane [75-83-2] encapsulated in acrylonitrile-Me methacrylate copolymer [30396-85-1] 10, and p-toluenesulfonic acid 2 parts were mixed together and heated to 80° for 1 min to obtain a foam having d. 42 kg/m3 and compressive strength 0.25 kg/cm2.
