Abstract: 1,162,024. Continuous nitrocellulose production. WOLFF & CO. A.G. 7 Oct., 1966 [26 Oct., 1965], No. 44945/66. Heading C3A. Nitrocellulose is produced continuously by a process wherein cellulosic material is intimately mixed for a period not exceeding five seconds in a mixing and disintegrating device with a nitrating acid having a water content lower than the normal water content conventionally required for the commercial production of a nitrocellulose of a given degree of nitration, to produce a liquor having a ratio by weight of cellulose to nitrating acid in the range 1: 20 to 1: 30, transferring the mixture to an afterreaction vessel, agitating the mixture in the vessel and delivering it to a thrust centrifuge in which the resultant nitrocellulose is separated from the nitrating acid. The water content is preferably 1-2% below the said normal water content. In an example, the product has an N content of 15% produced by an acid containing 14% water, 24% HNO 3  and 62% S 2 SO 4 ; a conventional acid for this product contains 16% water and 60% H 2 SO 4 . The product of the invention is less swollen and has a smoother surface than that of prior processes, facilitating easy separation of acid therefrom, and preventing substantial hydrolysis.
