Method for hydrolyzing cellulosic materials into reducing sugars

Depolymerized cellulosic material with low crystallinity obtained from

The invention relates to anti-fouling paints and is concerned with anti-fouling paints developed for inhibiting the fixation of marine organisms on structures which are immersed in sea water, the paints including at least one toxic substance uniformly incorporated into a discontinuous solid matrix which is insoluble in sea water and is dispersed in the paint, the matrix being at least partially formed from at least one substance which becomes soluble in sea water under the action of enzymes liberated by the marine organisms to be inhibited and/or by the bacterial film in contact with the surface of the paint. The paints according to the invention provide an effective life which is much longer than that of the known anti-fouling paints. The invention relates to an anti-fouling paint containing at least one toxic substance.

A process for the preparation of lactosylurea and the N-methylol derivative thereof which are usable as feed supplements for ruminants. According to this process, lactose and urea are heated to 70.degree.-110.degree. C. with a minimum of water and, if possible, this water is eliminated during the reaction. The crude reaction product can be purified by grinding with ice-water or ethanol and subsequent draining so as to eliminate by dissolution in such solvants the unreacted urea. The corresponding N-methylol derivative is obtained by the reaction with formaldehyde.

Process for the preparation of lactosylurea, its purification and its

A photosensitive material is provided in which at least one surface portion of a substrate contains 2,3-di-(2,3-diiodopropoxy)-propyl cellulose uniformly distributed therethrough. A photosensitive sheet material can be formed totally of 2,3-di-(2,3-diiodopropoxy)-propyl cellulose or in part thereof, provided that the surface thereof contains 2,3-di-(2,3-diiodopropoxy)-propyl cellulose. Upon exposure to an activating electromagnetic radiation in which the intensity is modulated according to the configuration of an image, a visible image is formed on the surface of the material. Provision is further made for bringing the surface of the material into contact with the substance which forms a colored compound upon reaction with iodine liberated upon subjecting the surface to activating electromagnetic radiation.

Photosensitive material containing 2,3-di(2,3-diiodopropoxy)-propyl

The invention relates to a new substance, namely 2,3-di-(2,3-diiodopropoxy)-propyl cellulose and to the production of the same by the action of a dihalogenopropyl ether of cellulose with an alkali metal allylate with iodine addition to the resulting 2,3-di-allyloxy propyl cellulose.
