A process for preparing high purity solutions of highly substituted lithium amide bases by direct reaction of lithium metal with highly substituted amine bases alone or in an ether solvent, a hydrocarbon solvent or in a mixed ether/hydrocarbon solvent mixture, optionally in the presence of a catalyst selected from tin salts and transition metal salts of Groups 4B, 5B, 6B, 7B, and 8 of the Periodic Table.

High purity formulations of highly substituted lithium amide bases

The process for deacidification of at least one book or other similarly sized cellulosic product the steps of which include:

Book drying process

This invention provides a process for deacidifying paper by contacting the paper one or more times with hydrocarbon or halocarbon solutions of certain magnesium and/or zinc alkoxyalkoxides which may have been treated with carbon dioxide to yield low viscosity solutions, drying the books and rehydrating the books.

Mass cellulose deacidification process

This invention provides a process for deacidifying paper by contacting the paper with hydrocarbon or halocarbon solutions of certain magnesium and/or zinc alkoxyalkoxides which may have been treated with carbon dioxide to yield low viscosity solutions.

Mass treatment of cellulosic materials

An organometallic composition containing copper(I) comprising:

Thermally stable, reactive organometallic compositions containing copper

A process for strengthening the cellulose in materials which have been treated with an alkaline organometallic compound selected from a metal alkyl, metal alkoxide or alkyl metal alkoxide to deacidify the cellulose and which cellulosic material is wet with treatment solvent, by treating the undried cellulosic material with a polar monomer and then drying the cellulose material and polymerizing the monomer by subjecting the treated cellulose to vacuum and heat.
