PURPOSE: To efficiently produce a dispersion by taking the dispersion of a hydrophobic material in water out of a static mixer without the loss of the water and introducing a mixture composed of the hydrophobic material and the water into the static mixer at a specified temp. CONSTITUTION: The liquid hydrophobic material is supplied at >=50 deg.C and below the deterioration temp. of the hydrophobic material into the static mixer where the hydrophobic material is mixed with water introduced therein under a pressure under which the water does not evaporate. The mixture is introduced at a temp. below the temp. in the static mixer into another cold static mixer kept at a temp. below the b. p. of the water and, thereafter, the mixture composed of the hydrophobic material and the water is mixed. The dispersion of the hydrophobic material into the water is then taken out of the static mixer without the substantial loss of the water and another mixture composed of the hydrophobic material and the water is introduced into this static mixer to disperse the hydrophobic material.
