Abstract
The major cause of paper deterioration is the deterioration of the cellulose in paper fibers. The deacidification of paper reduces the rate of this deterioration, and It has been reported to extend the useful life of acidic paper by three to five times [1].
It has been recognized the need for an effective method of deacidifying large quantities of books and
documents. The review of the current state of deacidification technology has been published recently [5]. The paper points to the immediate need for a cost-effective and reliable method to save the millions of books that prish every year [5].
It was tried to deacidify by the gaseous ethanolamine for solving above the problems. Acidic paper was treated with the monoethanolamine, diethanolamine, triethanolamine. In result, it was found that the rate of deacidification was in the order of the
monoethanolamine > diethanolamine > triethanolamine. But treated paper caused very little brigthness and fold endurance.
