Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
96 words
A METHOD OF REDUCING THE NORMAL TENDENCY OF A PARTICULATE NITROGEN-CONTAINING COMPOUND TO CAKE ON STANDING, SAID COMPOUND BEING SELECTED FROM THE GROUP CONSISTING OF AMMONUM, SODIUM, POTASSIUM, AND CALCIUM NITRATES, MONOAMMONIUM SULFATE, AMMONIUM SULFATE, AND UREA, WHICH COMPRISES COATING SAID COMPOUND WITH A MATERIAL WHICH COMPRISES, AS THE SOLE ESSENTIAL ANTI-CAKING AGENT, AN ADMIXTURE OF A MAJOR AMOUNT OF KAOLIN AND A MINOR AMOUNT OF AN ALKALI METAL SALT OF AN ALKYLARYL SULFONIC ACID, SAID AGENT BEING EMPLOYED IN AN AMOUNT SUFFICIENT TO REDUCE THE NORMAL TENDENCY OF SAID NITROGEN-CONTAINING COMPOUND TO CAKE ON STANDING.
