ABSTRACT:
Gases are removed from enclosed spaces by (1) purging the space to be enclosed with a reactive gas such as carbon dioxide, (2) adding a metal hydrocarbyloxide and a solid absorbent for the volatile reaction products of the reactive gas and the metal hydrocarbyloxide, e.g., a solid absorbent such as activated charcoal, and (3) enclosing the space, e.g., by hermetically sealing the container. This method for gas removal is particularly useful in the production of thermal insulating articles such as double walled vacuum containers for storage of foods and beverages.
