摘要:
A biologically-active compound which includes an inorganic mixed metal cationic portion having anion exchange properties and an anionic portion containing a biologically-active anion. The mixed metal cationic portion can be an oxide, hydroxide, or both, and can be fully hydrated, partially hydrated, or not hydrated. The biologically-active anion can be, e.g., an antibiotic, an analgesic, an antimicrobial, a pharmaceutical, an antioxidant, or an agricultural chemical such as a herbicide or a pesticide. These biologically-active compounds can have controlled-release properties and can be produced by relatively simple processes, using for the cationic portion relatively common starting materials. These biologically-active compounds are useful, for example, in compositions to form pharmaceuticals, antioxidants, or herbicides, and can be incorporated into a polymeric material to form a shaped body, such as a plastic film which can be utilized to form bags for food storage or transportation. Also included are processes for making the biologically-active compounds.

A reversible liquid solid phase change composition comprising hydrated Mg(NO.sub.3).sub.2 /MgCl.sub.2, and one of the group of MgO, Mg(OH).sub.2, and/or NaBO.sub.2, added to the composition in an effective amount to suppress super-cooling of the Mg(NO.sub.3).sub.2 /MgCl.sub.2 liquid phase.
摘要:
A reversible liquid/solid phase change composition for the storage of energy comprising a mixture of hydrated calcium bromide/calcium chloride and a modifier selected from KBr, KCl, or mixtures thereof, for modifying the semicongruent melting of the mixture to reduce the formation of crystalline CaBr.sub.2 and CaCl.sub.2 hydrate phases other than the hexahydrate phase. The composition is useful over a temperature range of from about 5.degree. to about 50.degree. C. and can be employed for the storage of coolness or heat, or as a buffer or heat sink to modulate diurnal swings in ambient temperature.

摘要:
A reversible liquid/solid phase change composition comprising a eutectic composition of CaBr.sub.2 .multidot.6H.sub.2 O and CaBr.sub.2 .multidot.4H.sub.2 O, having more than 5.4 but less than 6.0 moles of H.sub.2 O per mole of CaBr.sub.2. The composition optionally includes additives selected from KBr and NaBr to lower the melting point of the composition. The composition optionally also includes a nucleating agent selected from Ba and Sr salts to reduce supercooling of the composition to 5.degree. C. or less.
