  • Anti-caking agents for ammonium thiocyanate
    Patent number: 5630992
    Abstract: A composition comprising ammonium thiocyanate and an amount of an anti-caking agent selected from amines and amine salts, which is effective to reduce the caking of the ammonium thiocyanate, is disclosed. Also disclosed is a method for reducing the caking of a composition which contains ammonium thiocyanate which comprises the step of incorporating in said composition, 0.0001-1.0% by weight, based on the weight of the ammonium thiocyanate, of an anti-caking agent selected from amines and amine salts and the use of a compound selected from amines and amine salts, as an anti-caking agent for ammonium thiocyanate. It has surprisingly been found that minor amounts of these anti-caking agents provide an excellent reduction in the caking of ammonium thiocyanate compositions.
