    Abstract: A method of deacidifying paper wherein the paper has a substantially cellulose fiber base or substrate by exposing the paper to the vapors of a volatile organometallic compound and subsequently decomposing said compound to a base or alkaline material in situ. The treated material is usually first dried in vacuo and exposed under anhydrous or nearly anhydrous conditions to the organic-metallic compound. The method has the advantage of being able to treat large quantities of material at any one time.

    Abstract: A product including two or more plies with each ply including one absorbent layer and a second opposing fluid impervious layer. The two plies are arranged such that the fluid impervious layers face each other and are positioned at the inside of the two-ply product. The two plies are bonded on two or three sides to form a sleeve or a pocket, such that a hand can be inserted between the two plies and positioned in contact with one or both fluid impervious layers. In this manner, the product is absorbent on both sides, and can be utilized on both sides while preventing hand contact with the material absorbed or picked up by the product.

    Abstract: Process for conservation of a cellulosic material, comprising a treatment wherein said cellulosic material is contacted with a stabilising agent, and at least one of the cellulosic material or the stabilising agent is cooled before and/or during the treatment. A deacidification agent comprising magnesiumdipropoxycarbonate, propanol and an HFC selected from MFC-134a and EFC-227ea is particularly preferred as stabilising agent.
