摘要： An improved method of deacidifying books, imaged paper and other imaged materials having a cellulose base wherein, for a sufficient time to raise the pH of the materials, the materials are treated with alkaline particles of a basic metal oxide, hydroxide or salt dispersed in a hydrofluorether carrier, alone, or in combination with a perfluorinated carrier. A surfactant is added.

摘要： A method for temporarily revealing the presence of a watermark on cellulose-based materials. The method comprises applying one of a perfluorocarbon ard hydrofluorocarbon to at least a portion of the cellulose-based material. The method also provides applying a solution containing both perfluorocarbon and hydrofluorocarbon to the cellulose-based material to vary the rate of evaporation of the solution.

摘要： A method and apparatus for deacidification of cellulosic materials such as the pages of books, magazines, newspapers, documents and the like are provided which ensures that substantially the entirety of each page is treated. The method includes placing the materials within a carrier such that the pages are free for exposure to the treating medium. The carrier is submerged in a vat preferably containing a dispersion of treating material including particles of an alkaline metal oxide, hydroxide or salt. The vat includes a support frame which supports the carrier and is slidably mounted on the vat such that the carrier and materials it holds may reciprocate in a generally horizontal direction. The reciprocation of the support frame causes the pages of a book, for example, to fan out, and the treating material in the medium thus comes into contact with each page of the book, magazine or other document. After reciprocating the support frame at a preselected speed and stroke length for a preselected length of time such that each page of the book is treated, preferably in its entirety, the carrier is removed from the bath and transferred to a dryer. The dryer includes a flexible meshed webbing which is loosely draped over a series of support rods mounted on a frame. The cellulosic materials are placed on the meshed webbing and preheated air is passed through the dryer to evaporate any excess residual treating medium.
摘要翻译：提供了一种用于纤维素材料脱酸的方法和装置，例如书籍，杂志，报纸，文件等的页面，其确保了基本上整个页面的处理。该方法包括将材料放置在载体内，使得页面不会暴露于处理介质。将载体浸没在优选含有包括碱金属氧化物，氢氧化物或盐的颗粒的处理材料的分散体的槽中。槽包括支撑框架，其支撑载体并且可滑动地安装在槽上，使得其保持的载体和材料可以在大致水平的方向上往复运动。支撑框架的往复运动导致书籍的页面例如扇出，并且介质中的处理材料因此与书，杂志或其他文档的每一页接触。在以预选的速度和行程长度将预定的速度和行程长度往复运动之后，预定时间长度使得书的每一页都被处理，优选地整体地将载体从浴中移出并转移到干燥器中。干衣机包括柔性网状织带，其松散地覆盖在安装在框架上的一系列支撑杆上。将纤维素材料放置在网状织带上，并将预热的空气通过干燥器以蒸发任何多余的残余处理介质。

摘要： A mixture of monosubstituted and polysubstituted isopropylnaphthalenes is produced by treating naphthalene with concentrated sulfuric acid and propylene. Concentrated sulfuric acid is added to naphthalene in an amount of at least 3% based on the amount of naphthalene used, and at a temperature in the range of 150.degree. - 200.degree.C to form a mixture containing naphthalene sulfonic acids and naphthalene. Propylene is added to this mixture at a temperature of 150.degree. - 220.degree.C. The propylated mixture is neutralized with caustic and distilled to remove naphthalene and to produce a mixture of isopropylnaphthalenes.
