Hydantoin fungicides

Hydantoin fungicides. Ishimitsu, Keichi; Nakada, Akira; Murakami, Akira (Nippon Soda Co., Ltd., Japan). Japan. Kokai JP 51151331 25 Dec 1976 Showa, 6 pp. (Japanese). (Japan). 21885-74-5 and 34893-92-0 which are cas registry numbers are also used here. CODEN: JKXXAF. CLASS: IC: A01N009-22. APPLICATION: JP 75-76157 21 Jun 1975. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemicals) Section cross-reference(s): 28 The hydantoins I (A = O or iminof X and Y = halogen) are fungicides. Thus, 1-cyanomethyl-3-(3,5-dichlorophenyl)-4-iminoimidazolidin-2-one (II) [21885-74-5] applied to bean seedlings at 125 ppm totally prevented Sclerotinia sclerotiorum infection. II was prepd. by treating iminodiacetonitrile [628-87-5] with 3,5-dichlorophenyl isocyanate [34893-92-0]. .

Electrolytic diaphragms

Electrolytic diaphragms. Onoue, Yasuharu; Sata, Toshikatsu; Nakahara, Akihiko; Murakami, Shoji; Ito, Junichi (Tokuyama Soda Co., Ltd., Japan). Japan. Kokai JP 51122677 26 Oct 1976 Showa, 9 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C25B013-08. APPLICATION: JP 75-45292 16 Apr 1975. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Fabrication and Uses) Section cross-reference(s): 72 Sodium hydroxide was prepd. in good purity and good current efficiency by using fluoropolymers contg. carboxylate and sulfonate groups as electrolytic diaphragms. Thus, a vinylidene fluoride sheet was impregnated with styrene in the presence of an inhibitor, irradiated to give a styrene-vinylidene fluoride graft copolymer (I) [31566-66-2], swelled in ethylene dichloride, treated with chlorosulfonic acid at 70.degree., immersed in hot iminodiacetonitrile [628-87-5], heated in 4N NaOH at 60.There are some commonly used reagents with their cas registry numbers 112-24-3 and 504-24-5 in this article.degree. to prep. a diaphragm having current efficiency 88%, compared with 68% for a similar diaphragm prepd. from sulfonated I. .
