The process can be carried out continuously or discontinuously.
Abstract: There is disclosed herein novel organic-inorganic layered perovskites of the general formula A.sub.2 MX.sub.4 where A is an organic ammonium cation, M is a divalent rare earth metal and X is a halogen. These compounds can be made by a low temperature (about 100.degree.-160.degree. C.) solid state reaction between the organic ammonium salt with the appropriate hydrogen halide and MX.sub.2 where M is a divalent rare earth metal and X is a halogen). A specific example is (C.sub.4 H.sub.9 NH.sub.3).sub.2 EuI.sub.4 which has been made through a reaction at about 140.degree.-160 C. between C.sub.4 H.sub.9 NH.sub.2. HI and EuI.sub.2. This new compound produces intense blue photoluminescence at room temperature, with a peak wavelength of 460 nm and a fairly narrow peak width (FWHM=24 nm). In addition to the simple aliphatic ammonium cations of the form C.sub.n H.sub.2n+1 NH.sub.3.sup.+, e.g., propylammonium (C.sub.3 H.sub.7 NH.sub.3) and butylammonium (C.sub.4 H.sub.9 NH.sub.

Abstract: This invention relates to novel neopentyl difluoroamino compounds which are useful as plasticizers and oxidizers in energetic formulations, such as propellants, explosives, and gasifiers. These neopentyl difluoroamino compounds can be prepared either: (1) by the direct fluorination of amine derivatives containing energetic pendant groups; or (2) by first preparing NF.sub.2 -derivatives and then substituting these derivatives with energetic pendant groups. In particular, mono- and bis-(difluoroaminomethyl) oxetanes are synthesized and further reacted to yield the corresponding dinitrate esters. It has been discovered that these NF.sub.2 -dinitrate esters are very useful as energetic plasticizers in high-energy formulations.
