Title: Improvements in or relating to isotopic exchange processes
Inventor: POOLE KEITH RODERICK
IPC: C01B4/00
Filed: 1965-03-10
Abstract: A process for the production of D2-enriched materials by the dual temperature NH3-H2 exchange process in which a stream of H2 from the hot tower is cooled to the temperature of the cold tower before being passed to the cold tower, whereby NH3 in the H2 stream is condensed then cracked to give N2 and H2 and this mixture is passed in isotope exchange with liquid NH3 in a cold tower.  The mixture may be mixed with the H2 stream and passed to the cold tower of the dual temperature system. Alternatively a small bleed flow from the cold tower of the dual temperature system may be enriched by being passed in isotope exchange with the cracked NH3 in a second cold tower. The cracked NH3 stream from the second cold tower may be mixed with the H2 stream being passed to the cold tower of the dual temperature system.  A major part of the further enriched stream may be cracked and passed in isotope exchange with the minor part in a third cold tower.  D2 make-up may be effected by adding natural H2 to and withdrawing depleted H2 from said H2 stream.  H2 is enriched in D2 in the hot tower.  The cracking of NH3 may be at 600-1000 DEG  C. under pressure using a catalyst e.g. supported nickel oxide.  The liquid NH3 may contain 35 g/l. KNH2 and 6% weight pyrrolidine.

Title: Resin compositions and curing agents therefor
IPC: C08G59/50
Filed: 1957-03-28
Abstract: Epoxy resins having a 1,2-epoxy equivalency greater than 1 are cured by heating them with diaminodiphenyl sulphones.  From 25 to 125 per cent of the equivalent amount of the sulphone may be used. The 3,31, 4,41 and 2,21-isomers may be used also mixed isomers such as the 2,31, 2,41 or 3,41-diamino diphenyl sulphones as well as substituted sulphones such as 3,31 - diamino, 4,41 - dichlorodiphenylsulphone and 3,31-diamino, 4,41-dimethyldiphenyl sulphone.  Although the 3,31-diaminodiphenyl sulphones and their 4,41-disubstitution products are solids, they may be dissolved in liquid epoxy resins and the rate of cure is sufficiently slow to permit complete solution before curing occurs.  Adducts of epoxy resins and the sulphones may be obtained by partial reaction of the mixture to form a solid product which may then be ground and stored.  Glycidyl ethers suitable for curing are the diglycidylether of glycerol, and of bisphenol and other polyethers of higher molecular weight.  In Example (1), 62 gs. of 3,31-diaminodiphenyl sulphone are mixed with 100 gs. of a glycidyl ether having an epoxy equivalency of 200 and dissolved by gently heating.  On heating the liquid for 5 hours at 150 DEG  C. a tough plastic was obtained.  Other examples illustrate the use of the isomers specified above.
