Proceedings of Pre-symposium of the 10th ISWPC Deacidification of Paper by the Gaseous Ethanolamines Treatment

The major cause of paper deterioration is the acid-catalyzed hydrolysis of 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 bee 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.
