Abstract

PURPOSE: To perform breaking of foams of a foamable aqueous soln. produced in chemical industry, etc. by forming the antifoaming agent in the form of an aqueous soln. of the water-soluble polycondensate obtained by reacting the specific molar ratios of NH3 and epichlorhydrine.
CONSTITUTION: An antifoaming agent sprayed to foams for the purpose of breaking the foams and an antifoaming agent to be added and mixed in a foamable aqueous soln. for the purpose of suppressing the foams of the foamable aqueous soln. are an aqueous soln. of ammonia-epichlorhydrin polycondensate. This antifoaming agent is the polycondensate comprising the proportions of 0.9W2.5:1 molar ratios epichlotrydrine and ammonia and their hydrochlorides acetates which are water soluble. Said agent is easily synthesized from these raw materials. This antifoaming agent is effectively utilized for antifoaming as a measure against faults owing to foaming in chemical industry and microbial industry.
