Abstract: A solvent-free molten salt method for the synthesis of glycidyl azide polymer.

Abstract: A method of producing a hydroxy-terminated aliphatic polyether utilizing a specific catalytic interaction to enhance the solubility and resulting reactivity of an azide moiety.

Abstract: A chemical iodine laser system 10 is provided with a reactive iodine producing container (12) for housing a reactive iodine generating composition. Singlet delta oxygen produced by oxygen generator (30) is mixed with iodine atoms and conveyed to a laser cavity.

Abstract: A direct low temperature process for the preparation of pure magnesium borohydride diammoniate or the deuterated analog thereof based on the addition of 90-95% of the stoichiometric amount of NH.sub.3 to an excess of Mg(BH.sub.4).sub.2.X(C.sub.2 H.sub.5).sub.2 O in a benzene reaction solvent in accordance with equation 1: ##STR1## wherein X is a numeral from about 2.0 to about 2.5; or when the reaction is conducted in an ether reaction solvent with the same quantities of reactants and under the same experimental conditions, the triammoniate or the deuterated analog thereof is formed in accordance with equation 2: ##STR2## wherein X is a numeral from about 2.0 to about 2.5. In either case the pure product is readily isolated by filtration, solvent washing to remove excess Mg(BH.sub.4).sub.2.X(C.sub.2 H.sub.5).sub.2 O, and vacuum drying at ambient temperature. Yields are 95-99%; purities are typically about 97%.

Abstract: A singlet delta oxygen generator 10 comprises a static or motionless mixer 12 having a gas inlet 14 through which chlorine gas reactant is introduced into the static mixer and a liquid inlet 16 through which the basic sodium hydroxide/hydrogen peroxide solution is introduced. As the reactants pass through static mixer 12, the gaseous products and liquid by-products are formed. The product stream passes through liquid/gas separator 26 wherein the liquid by-product stream is diverted to sump 28 and the gaseous product stream is conveyed to a low volume trap 30. The temperature of trap 30 is maintained at approximately -80.degree. C. so as to solidify and thereby remove any water or hydrogen peroxide vapor which might remain in the product stream. From the low volume trap 30, the product stream is then conveyed to chlorine trap 34 wherein any excess chlorine gas present in the system is retained.

Abstract: A method and generator are provided for producing singlet molecular oxygen, O.sub.2 (.sup.1 .DELTA..sub.g). A hypohalite selected from the group consisting of BrSO.sub.3 F, BrNO.sub.3, BrOCF.sub.3, ClSO.sub.3 F, ClNO.sub.3, Cl0CF.sub.3, FSO.sub.3 F, FOCF.sub.3, and ISO.sub.3 F, is reacted with hydrogen peroxide to produce singlet molecular oxygen. A preferred embodiment of the reaction is illustrated by the following example:ClSO.sub.3 F + H.sub.2 O.sub.2 .fwdarw. O.sub.2 (.sup.1 .DELTA..sub.g) + HSO.sub.3 F + HCl.The generator for producing the singlet molecular oxygen is a reactor vessel having nozzles for introducing the chlorine fluorosulfate and hydrogen peroxide into the vessel. An outlet is provided for withdrawing the products, and the singlet molecular oxygen is separated by condensing out the other products in a condensor.
