    • Elastomers having a polyurethane binder are formed from a mixture including tetrastar polyethylene oxide polyol with a molecular weight of at least 16000 daltons and a plasticizer present in a ratio of at least five parts by weight to one part of the polyol and provide high tensile strength, extreme elongation, great flexibility, and absence of voids. Energetic elastomers use a nitrate ester plasticizer with a curative having a functionality of at least three and an NCO/OH equivalent ratio of about 2.5 and may include an energetic particulate filler. Inert elastomers use a non-volatile ester plasticizer, as dimethyl phthalate, with a curative having a functionality of two and an NCO/OH equivalent ratio not over 2.0. Inert elastomers simulating mechanical properties of energetic elastomers including a nitrate ester use plasticizers, as a non-volatile ester and a mixture including a bromoaromatic derivative, having densities above and below the nitrate ester density, 1,2,4-butanetriol trinitrate being replaced with dimethyl phthalate and a mixture of pentabromodiphenyl ether and an aryl phosphate. A particulate energetic organic filler is simulated by an inert organic chlorine derivative of similar density, cyclotetramethylenetetranitramine being replaced by 1,2,3,4,7,8,9,10,13,14,14-dodecachloro-1,4,4a,5,6,6a,7,10,10a,11,12,12a-dodecahydro-1,4,7,10-dimethanodibenzo (a,e) cyclooctene and permitting particulate aluminum to be used in the same proportions as in an energetic elastomer.

    • Calcium formate is heated to a temperature in the range of from 300.degree. to 400.degree. C to form calcium carbonate, hydrogen and carbon monoxide and the gases are bled off. The calcium carbonate is then heated to about 825.degree. C whereby calcium oxide and carbon dioxide are formed and the gas is again bled off. The calcium oxide is then reacted with water to form calcium hydroxide and the calcium hydroxide is reacted with carbon monoxide to regenerate calcium formate and start the process over again. The process provides a convenient method for obtaining a mixture of hydrogen and carbon monoxide gases which are useful for many purposes. The carbon monoxide may be removed from the mixture of gases produced to obtain hydrogen which also finds many uses. Further, a mixture of hydrogen and carbon monoxide suitable for use in the Fischer-Tropsch reaction may be readily produced.
    • 将甲酸钙加热至300-400℃的温度,以形成碳酸钙,氢气和一氧化碳,并将气体排出。 然后将碳酸钙加热至约825℃,由此形成氧化钙和二氧化碳,并再次将气体排出。 然后将氧化钙与水反应形成氢氧化钙,氢氧化钙与一氧化碳反应以再生甲酸钙并重新开始该过程。 该方法提供了一种用于获得氢和一氧化碳气体的混合物的方便方法,其可用于许多目的。 一氧化碳可以从产生的气体的混合物中除去,以获得也具有许多用途的氢。 此外,可以容易地制备适用于费 - 托反应的氢气和一氧化碳的混合物。
