    Abstract: THE INVENTION PROVIDES A PROCESS CAPABLE OF EASILY PRODUCING A WATER-SOLUBLE SALT OF A NAPHTHALENESULFONATE FORMALDEHYDE CONDENSATE WITH A REDUCED AMOUNT OF UNREACTED FORMALDEHYDE. WHEN NAPHTHALENESULFONIC ACID IS SUBJECTED TO CONDENSATION REACTION WITH FORMALDEHYDE TO PRODUCE A NAPHTHALENESULFONATE FORMALDEHYDE CONDENSATE, A SULFITE IS ADDED TO THE REACTION SYSTEM AFTER THE CONCLUSION OF THE CONDENSATION REACTION. WHEN A CEMENT DISPERSANT COMPOSITION IS OBTAINED, THE PROCESS INCLUDES A STEP OF NEUTRALIZING THE CONDENSATE.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for easily producing a naphthalenesulfonic acid formaldehyde condensate water-soluble salt which is decreased in the quantity of unreacted formaldehyde, produces a product stabilized in quality, and is reduced in the load to the environment, and thus is suitably applied to a cement dispersing agent.
    SOLUTION: When producing the naphthalenesulfonic acid formaldehyde condensate by condensating naphthalenesulfonic acid and formaldehyde, a sulfite is added to the reaction system after terminating the reaction. When obtaining a cement dispersing composition, a process of neutralizing the condensate is provided.

    Abstract: PURPOSE: To obtain an chemical admixture composition capable of reducing viscosity of concrete without damaging water reducing properties by blending a formaldehyde co-condensate with specific aromatic compounds with a defoaming agent. CONSTITUTION: This chemical admixture composition for a concrete product comprises a formaldehyde co-condensate with one or more aromatic compounds (A) into which 1-300mols of a 2-3C oxyalkylene group are introduced and one or more carboxyl group-containing aromatic compounds (B) or its neutral salt (X) and a defoaming agent (Y) as necessary components. By introducing the alkylene oxide group to the aromatic formaldehyde co-condensation system, expulsive force of steric hindrance of the alkylene oxide is added to electric expulsive force of essential aromatic system to extremely raise dispersing effect. The use of the defoaming agent with the co-condensate further improves reduction in viscosity and foam entraining properties.
