摘要： The invention relates to Group 1 metal/silica gel compositions comprising silica gel and an alkali metal or an alkali metal alloy. The compositions of the inventions are described as Stage 0, I, II, and III materials. These materials differ in their preparation and chemical reactivity. Each successive stage may be prepared directly using the methods described below or from an earlier stage material. Stage 0 materials may, for example, be prepared using liquid alloys of Na and K which are rapidly absorbed by silica gel (porous SiO 2 ) under isothermal conditions, preferably at or just above room temperature, to form loose black powders that retain much of the reducing ability of the parent metals. When the low melting Group 1 metals are absorbed into the silica gel, a mild exothermic reaction produces Stage I material, loose black powders that are indefinitely stable in dry air.; Subsequent heating to 400° C produces Stage II materials, which are also loose black powders. Further heating above 400° C forms Stage III material with release of some Group 1 metal. It is believed that Stage I, II and III materials represent reductions of the silica gel after absorption of the Group metal. Preferred Group 1 metal/silica gel compositions of the invention are those containing sodium, potassium, or sodium-potassium alloys with sodium and sodium- potassium alloys being most preferred. Each stage of the Group 1 metal/silica gel composition of the invention may be used as a reducing agent reacting with a number of reducible organic materials in the same manner known for alkali metals and their alloys.

摘要： La invencion se relaciona a composiciones de metal del Grupo 1/gel de silice que comprenden gel de silice y un metal alcalino o una aleacion de metal alcalino. Las composiciones de la invencion se describen como materiales de Etapa 0, I, II y III. Estos materiales difieren en su preparacion y reactividad quimica. Cada etapa sucesiva se puede preparar directamente utilizando los metodos descritos despues o a partir de un material de etapa mas temprana. Los materiales de Etapa 0, por ejemplo, se pueden preparar utilizando aleaciones liquidas de Na y K que se absorben rapidamente mediante el gel de silice (SiO2 poroso) bajo condiciones isotermicas, de preferencia en o precisamente arriba de la temperatura ambiente, para formar polvos negros sueltos que retienen mucha de la habilidad de reduccion de los metales de origen. Cuando los metales del Grupo 1 de baja fusion se absorben en el gel de silice, una reaccion exotermica leve produce polvos negros sueltos de material de Etapa I que son indefinidamente estables en aire seco. El calentamiento subsecuente a 400 degree C produce materiales de Etapa II, que tambien son polvos negros sueltos. El calentamiento adicional arriba de 400 degree C forma material de Etapa III con liberacion de algo de metal del Grupo 1. Se cree que los materiales de Etapa I, II y III representan reducciones del gel de silice despues de la absorcion del metal del Grupo 1. Las composiciones de metal del Grupo 1/gel de silice preferidas de la invencion son aquellas que contienen sodio, potasio o aleaciones de sodio-potasio, con el sodio y las aleaciones de sodio-potasio que son los mas preferidos. Cada etapa de la composicion de metal del Grupo 1/gel de silice de la invencion se puede utilizar como un agente de reduccion que reacciona con un numero de materiales organicos reductibles de la misma manera conocida para metales alcalinos y sus aleaciones.

摘要： The invention relates to lithium metal/porous metal oxide compositions. These lithium metal compositions are prepared by mixing liquid lithium metal with a porous metal oxide in an inert atmosphere under exothermic conditions sufficient to absorb the liquid lithium metal into the porous metal oxide pores. The lithium metal/porous metal oxide compositions of the invention are preferably loaded with lithium metal up to about 40% by weight, with about 20% to 40% by weight being the most preferred loading. The invention also relates to lithium reagent-porous metal oxide compositions having RLi absorbed into a porous oxide. The preparation and use of these compositions are also described.
