One-step production of polyamines from isocyanate-containing prepolymers and their use in preparing polyurethanes: One-step production of polyamines from isocyanate-containing prepolymers and their use in preparing polyurethanes. Rasshofer, Werner; Dieterich, Dieter (Bayer A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3223397 A1 29 Dec 1983, 74 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07C085-20; C07C087-58; C07C087-50; C07C087-14; C08G018-32. APPLICATION: DE 82-3223397 23 Jun 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Polyamines contg. 0.19-20.3% arom. and/or aliph. NH2 groups are prepd. by the hydrolysis of isocyanates or prepolymers contg. 0.5-40% NCO in the presence of (bi)carbonates or carboxylates and H2O-sol. solvents. Thus, adding 500 g polypropylene glycol bis[3-isocyanato(methyl)phenylcarbamate] [9051-58-5] (glycol OH no. 56) over 30 min to 1500 mL DMF contg. 250 mL H2O and 5 g KOAc [127-08-2] at 90° gave a polyamine with yield 94%, NH2 content 0.76%, total N content 2.46%, amine no. 30.4-31.1 mg KOH/g, H2O content 0.Except for chemicals metioned above, 39349-83-2 and 89344-68-3 are also used.1%, and viscosity 710 mPa-s at 75°. .

EP 92199 A1 26 Oct 1983, 17 pp. DESIGNATED STATES: R: DE, FR, GB. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C09K005-06. APPLICATION: EP 83-103671 15 Apr 1983. PRIORITY: JP 82-62406 16 Apr 1982; JP 82-203614 22 Nov 1982. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) A heat-storage material for air-cooling systems comprises HOAc [64-19-7] or a mixt. of HOAc and 31 acetate and is further added with 31 anhyd. 64-19-7 and 12125-02-9 are cas registry numbers of chemicals which are used as reagents here. halide as nucleating agent to prevent supercooling. Thus, a heat-storage material was prepd. from HOAc with NaOAc [127-09-3] 5, KOAc [127-08-2] 3, and CaCl2 0.01%. The material was subjected to 20 cycles of heating to 25° and then cooling to -5°. Supercooling was <0.1° vs. 5.5-6° for material without CaCl2. .
