    摘要： Cyclic nitramines of the formula ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 are independently selected from the group consisting of H, NO and NO.sub.2, and acid salts of the compound in which R.sup.1, R.sup.2 and R.sup.3 are each H, are disclosed. These compounds are useful as components in energetic compositions, including rocket and gun propellants and explosives, and are of particular interest due to their combination of high energy output and insensitivity. Compounds in which R.sup.3 is H or NO are further useful as intermediates in the preparation of those in which R.sup.3 is NO.sub.2. Also disclosed is a method for producing such compounds involving the reaction between hexamethylenetetramine and nitroguanidine.

    摘要： Tocopherols are isolated from vegetable oil distillates and other saponifiable substances in which tocopherols are naturally present, by saponification in an alcoholic medium, followed by metathesis with a zinc halide. The resulting zinc salts of fatty acids are readily precipitated out of solution without mechanical granulation or the addition of powdering agents, leaving the tocopherols in alcoholic solution from which they are readily recovered. The sterols and glycerol are also recoverable for use in other applications.

    摘要： Hydroxy-terminated aliphatic polyethers having the formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently selected from the group consisting of H, CH.sub.2 N.sub.3 and CHN.sub.3 CH.sub.2 N.sub.3, such that the total number of azide groups per monomer unit is two to four, and n is an integer from 2 to 40, display unique properties as energetic polymers. Co-polymers of the monomer units in the above formula with other, known azido-substituted monomer units further provide energy outputs at preselected levels based on the proportions of each type of monomer present.

    摘要： Reactions of ring systems, such as aziridines, oxetanes and oxiranes with carboxylic acids, anhydrides, imides, lactones and carbonate esters are catalyzed by C3-C60, substituted or unsubstituted, straight or branched-chained, alkyl, aryl, or aralkyl carboxylate Cr+3 salts, preferably chromium +3 octoate. The catalysts also accelerate the reaction of hydroxy compounds with anhydrides, and of thiiranes with anhydrides. The catalysts selectively enhance the conversion of ring systems to form monomers, prepolymers, copolymers, functional end-group monomers, functional end-group prepolymers, and functional end-group polymers rather than forming homopolymers. By varying the catalyst concentration, molar ratios, and reaction temperatures, the reaction time required to form the desired product can be controlled.
