Granted: 1990-11-27
Abstract: PRODUCTION OF HIGH-STRENGTH, STORAGE-LINKAGE               PARTICULATE UREA               ABSTRACT OF THE DISCLOSURE One approach to improving storage stability, particularly that attribute characterized by reduction in the tendency for caking during storage of freshly prepared urea particles such as granules, is to treat the  surface  areas  of  the  freshly  prepared  parti-cles/granules with appropriate  amounts  and kinds of conditioning agents.   This approach does not address the problem of increasing the hardness of the particles to   impart   improved  high-strength   characteristics thereto.  A second approach to this problem of improv-ing  storage  stability of urea granules is to admix and/or react certain anticaking and hardness improving additives  into or with the urea melt prior to the solidification of  urea particulates  therefrom.   The instant invention is directed to this second approach of imparting to the ultimately prepared urea particles both improved anticaking and hardness (as opposed to being easily crushed, i.e., friable) characteristics by means of addition to the urea melt of certain addi-tives.  The additives discovered and now disclosed as a principal feature of the instant invention are from the class of compounds known as lignosulfonates and are added in  such minute quantities that  although  they impart  the  improved  desired  characteristics  to  the particles formed from said melt, they neither add nor detract substantially from other properties thereof.

Application to the production of articles capable of absorbing aqueous fluids, particularly in the hygiene and agricultural fields.
