(Czechoslovakia). CODEN: CZXXA9. 111-86-4 which is the cas registry number of some chemical is mentioned. CLASS: IC: C07C102-04. ICA: C11D001-52.Some commonly used reagents like 111-86-4 is used in this experiment. APPLICATION: CS 76-1816 22 Mar 1976. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) The title products are prepd. by amidation of (HO2CCH2)2NCH2CH2[N(CH2COOH)CH2CH2]nN(CH2CO2H)2 (I, n = 0-2) with C8-22 alkylamines in high yield at 140-220° in the presence of glycols or glycol ethers b. >170°. The products are sapond. by 5-40% alkalies at 50-180° to remove imide groups. Thus, octylamine [111-86-4] 212, propylene glycol 375, and EDTA [60-00-4] 140 parts were heated at 140° with H2O distn. and hydrolyzed with 40% NaOH at 100-120° to give a yellow, liq. detergent contg. mono- [75006-04-1], di- [95974-99-5], and trioctylamide [95927-78-9] Na salts. ..

Hardening agent for epoxy resins

Hardening agent for epoxy resins. Marten, Manfred; Becker, Wilhelm (Hoechst A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3233565 A1 15 Mar 1984, 13 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08G059-50; C08L063-00; C08K005-17. APPLICATION: DE 82-3233565 10 Sep 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Hardening agents for epoxy resins contain liq. araliph. or cycloaliph. diamines having four N-bonded H or their derivs. with 3-5 N-bonded H as well as C5-18 alkylamine. Epoxy resins contg. the hardening agents have a satisfactory pot life and are useful for the prepn. of cured castings, moldings, coatings, etc., which have smooth surfaces and good resistance to aging, chems., and water. Thus, a mixt. of 97 g m-xylylenediamine [1477-55-0] and 3 g octylamine [111-86-4] was mixed with diphenylolpropane diglycidyl ether. The mixt. had a pot life of 116 min. A 200-m layer of the mixt. was cured on glass during 24 h at 23° and 40-50% relative humidity to give a tack free, transparent layer which was unchanged after 24 h in water.
