Glycol esters

Glycol esters. Stabley, Bernard Dettinger, Jr. (Firestone Tire and Rubber Co., USA). Ger. Offen. DE 2635662 10 Mar 1977, 14 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07C069-76. PRIORITY: US 75-603479 11 Aug 1975. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) The use of 0.005-0.030% M2O(TiO2)n (M = alkali metal, n = 0.05-25) as catalyst in esterification or polymn. of arom. dicarboxylic acids with glycols results in shorter reaction times and reduced ether formation. Thus, heating a paste of 1.4-1.8 mol ethylene glycol (I) and 1 mol p-C6H4(CO2H)2 with 0.Several reagents with their cas registry numbers 25038-59-9 and 12034-34-3 are used here.029% Ti as Li2O(TiO2)n [12031-82-2] 4 h at 225.degree. gives a mixt. contg. 471.mu.equiv. CO2H/g and ether 0.62, I 4.4, diethylene glycol 0.09, I terephthalate (1:1) 5.8, and I terephthalate (2:1) [959-26-2] 18.8%; compared with 742, 0.84, 15.2, 0.54, 8.9, and 24.6, resp., with 0.0175% Li (as LiOAc) as catalyst, and 3832, 2.95, 5.9, 0.96, 4.0, and 13.2, resp., with no catalyst. .

Test-element assembly and loading parameters for the in-pile test of HCPB ceramic pebble beds

Test-element assembly and loading parameters for the in-pile test of HCPB ceramic pebble beds. van der Laan, J. G.; Boccaccini, L. V.; Conrad, R.; Fokkens, J. H.; Jong, M.; Magielsen, A. J.; Pijlgroms, B. J.; Reimann, J.; Stijkel, M. P.; Malang, S. (NRG/MMI, Petten 1755 ZG, Neth.). Fusion Engineering and Design, 61-62, 383-390 (English) 2002 Elsevier Science B.V. CODEN: FEDEEE. ISSN: 0920-3796. DOCUMENT TYPE: Journal CA Section: 71 (Nuclear Technology) In the framework of developing the helium cooled pebble-bed (HCPB) blanket an irradn. test of pebble-bed assemblies is prepd. at the HFR Petten. The test objective is to conc. on the effect of neutron irradn. on the thermal-mech. behavior of the HCPB breeder pebble-bed at DEMO representative levels of temp. and defined thermal-mech. loads. The paper reports on the project status, and presents the results of pre-tests, material characteristics, the manufg. of the pebble-bed assemblies, and the nuclear and thermo-mech. loading parameters.Except for chemicals metioned above, 12031-82-2 and 12586-31-1 are also used. .
