Book excerpt: Excerpt from Determination of Cellulose in Rubber Goods In our opinion the method oi Hillen could not be acceptable because of the presence of rubber, substitutes, and other organic material during the immersmn m copper-ammonia. It is not im prob able that precipitates are obtained, when the sulphuric acid is added, that are other than cellulose. But what is more impor tant, it is an uncertain thing to attempt to remove cellulose from a rubber compound with which it has been intimately mixed by a process which can be likened unto extraction. Therefore it was decided that the rubber must first be removed before any attempt could be made to determine the cellulose by any procedure. The most convenient way\to accomplish the removal of rubber from the sample was found to. Be through the use of cresol. Early experimentation with cresol (b. P. 198° C) had indicated that it would effect this solution at 160 to 185° C in from 2 to 4 hours, depending on the coefficient of vulcanization, and that the result ing solution after it had been diluted with petroleum ether (b. P. About 45 to 50° C) would allow the fillers to settle out in a very short length of time, after which it could be filtered easily and rapidly. Samples of cotton, free from moisture, were immersed in cresol and allowed to remain for the maximum period of 4 hours at 185° C The solution was diluted with petroleum ether and filtered. The weight of the washed and dried cellulose after this treatment was identical with the weight of sample taken. The use of cresol was therefore adopted to remove the rubber as the first step in the method as outlined. From this point we. Proposed to remove the fiber, and determine it as the loss in weight occasioned by the process of solution. Obviously, all min eral fillers which would be affected by the reagents used to dis solve the cellulose would have to be removed beforehand-l Like wise the reagents used to remove these fillers. Must not affect the cellulose. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
