The acidification of paper, its intuitive manifestation is that the paper becomes low strength, fragile, easy to crack, yellowing and brittle. The main factor that causes the acidification of paper is that the cellulose (C ₆ H ₁₀ O ₅ ) n of the paper accelerates the hydrolysis under the catalysis of the acid, resulting in a shorter cellulose length and a decrease in the mechanical strength of the paper.
