Resins from formaldehyde

Resins from formaldehyde. CIV. Hydroxymethylation of diisopropyl ketone with formaldehyde. Ouchi, Tatsuro; Arita, Yoshitaka; Imoto, Minoru (Fac. Eng.Chemicals with cas numbers 15904-30-0 and 144-19-4 also play role., Kansai Univ., Suita, Japan). Polym. J., 8(5), 477-9 (English) 1976. CODEN: POLJB8. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 23 Diisopropyl ketone (I) [565-80-0] was hydroxymethylated with HCHO in the presence of LiOH to prep. monomers for photodegradable polymers. The addn. of 1 MeO group to I gave 2,2,4-trimethyl-1-pentanol-3-one (II) [15904-30-0], which, when treated further with HCHO gave 2,2,4-trimethyl-1,3-pentanediol (III) [144-19-4] instead of the 1,5-pentanediol deriv. The rate to form II was 14 times faster than that to form III, although their activation energies were nearly the same. This was explained by proposing a cross-Cannizzaro reaction to form III. .

Stabilization of trichloroethane for metal degreasing

Stabilization of trichloroethane for metal degreasing. Shinoda, Kiyonori; Konno, Kohji; Isozaki, Mitsuo; Funabashi, Masayuki (Kureha Chemical Industry Co., Ltd., Japan). Japan. JP 51036242 B4 7 Oct 1976 Showa, 3 pp. (Japanese). (Japan). CODEN: JAXXAD. CLASS: IC: C07C019-02. APPLICATION: JP 70-111885 16 Dec 1970. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) MeNO2, 1,4-dioxane, 1,2-epoxybutane, thiophene, and .gtoreq.1 of diisopropyl ketone, diisobutyl acetate, and diisopropylamine are added to MeCCl3 [71-55-6] for metal degassing. The additives prevent decompn. of MeCCl3, thus preventing corrosion of metals during degreasing. Thus, 100 mL MeCCl3 contg. 1,4-dioxane [123-91-1] 1.0, MeNO2 [75-52-5] 0.2, 1,2-epoxybutane [106-88-7] 0.5, thiophene [110-02-1] 0.05, diisopropyl ketone [565-80-0] 0.5, and diisopropylamine [108-18-9] 0.003% were poured into a 150-mL round-bottom flask equipped with a reflux condenser and Soxhlet extractor. A polished 2024 Al alloy [12616-84-1] specimen (45 .times. 18 .times. 1 mm) was dipped in the MeCCl3, and another Al alloy specimen was put in the gas phase at the bottom part of the reflux condenser. Then, the flask was heated in an oil bath at 100.degree. for 24 h. No corrosion of either Al alloy specimen was obsd.
