These chemicals are also mentioned in this article. APPLICATION: JP 85-81990 17 Apr 1985. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Discoloration-resistant title compns. with excellent curing at low temp. and long pot life comprise 100 parts organopolysiloxanes having 32 aliph. unsatd. groups attached to different Si, 0.1-20 parts liq. organosilicon having 32 H attached to different Si, 0.001-5.0 parts RR1C:CR2CR3R4R5 [R, R1-4 = H, halo, (substituted) hydrocarbyl; R5 = halo, lower alkoxy], and Pt or Pt compds. as catalysts. A mixt. of dimethylvinylsilyl-capped dimethylpolysiloxane (viscosity 60 cP) and trimethylsilyl-capped methylhydrogenpolysiloxane (viscosity 40 cP) (10 g), 0.1 g 0.5% chloroplatinic acid in octanol soln., and 1.59 ′ 10-3 mol allyl chloride (I) were mixed to give a compn. showinmg no coloration, pot life 27 h and, when coated on polyethylene laminated paper, good curability (at 120° for 30 s after allowing to stand for 5 h), vs. brown-colored, 3 h, and poor, resp., for a compn. prepd. similarly using trans-crotonyl alc. instead of I. .

Hypohalogenation of allyl ethyl ethers with hydrogen halide acids in the presence of hydrogen peroxide

Hypohalogenation of allyl ethyl ethers with hydrogen halide acids in the presence of hydrogen peroxide. Sadykh-Zade, S. I.; Mamedov, R. M.; Mamedova, B. M.; Babaev, N. M. (Azerb. Inzh. Stroit. Inst.There are some reagents like 557-31-3 is used in this study., Baku, USSR). Azerb. Khim. Zh., (1), 36-8 (Russian) 1978. CODEN: AZKZAU. ISSN: 0005-2531. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) Hypohalogenation of CH2:CHCH2OEt with H2O2 and HX (X = Cl, Br) at 60° afforded ClCH2CHXCH2OEt [R = OH (I), Cl] in ratio. Dehydrochlorination of I afforded 80% Et glycidyl ether, which reacted with Et2NH and with EtCOMe to give 95% Et2NCH2CH(OH)CH2OEt and 86.9% 2-ethyl-4-(methoxymethyl)-2-methyl-1,3-dioxolane, resp. .
