Abstract

PROBLEM TO BE SOLVED: To obtain an additive which hardly causes foaming in its use and reduces the friction resistance of a water-base medium in a wide temp. range from low to high temps. by using a combination of an amine oxide having an aliph. hydrocarbon group with a lower alcohol. SOLUTION: A low-foaming friction resistance reducing agent for a water- base medium is obtd. by incorporating an amine oxide (A) represented by formula I (wherein R<1> is an 8-22C linear or branched, satd. or unsatd. hydrocrbon group; R<2> and R<3> are each methyl, ethyl, or a group represented by formula II; (n) is 1-5; and Y is H or methyl) and a lower alcohol represented by the formula: R<4> OH (wherein R<4> is a 1-4C linear or branched alkyl) in a wt. ratio of (95/5)-(20/80) into the same. If necessary, an org. acid or its salt (C) may be incorporated further in a wt. ratio of C/(A+B) of (0/100)-(60/40). The friction resistance of a water-base medium is reduced by adding the reducing agent to the medium in an amt. of the amine oxide of 0.001-5% based on the medium.

2. Description of the Related Art The reduction of frictional resistance when a small amount of a specific substance is added to a turbulent flow in a pipe is generally known as a drag reduction effect. When a polymer compound is used, the polymer chain is broken when flowing through a pump or a bent tube, and there is a disadvantage that the drag reduction effect is not exhibited. Therefore, the polymer compound cannot be used as a drag reducing agent for a long time due to its mechanical deterioration. On the other hand, a drag reduction method by adding a surfactant has been considered. Surfactants are considered to form micelles in an aqueous medium and exhibit a drag reducing effect, and do not cause mechanical deterioration, so that they can be used as drag reducing agents for a long time.

A method using a surfactant such as an amine oxide as a drag reducing agent has been proposed. In addition, the present inventors have proposed that the usable temperature is wider than that of the conventional technique by combining a specific amine oxide or an amine oxide with an organic acid (Japanese Patent Application No. Hei 8-11654).
Nos. 3 and 116544). However, when these surfactants are used in actual piping, foaming occurs once air is entrained due to the shearing force of the pump or bending in the piping, etc., which causes cavitation and reduces the intended drag. In addition to impairing the effect, there were also problems such as the cooling tower overflowing with bubbles.
