Title:
COMPOSITE PARTICLE, METHOD FOR PRODUCING THE SAME, OIL SEPARATION AGENT, AND OIL-WATER SEPARATION METHOD
Document Type and Number:
Japanese Patent JP2020063375
Kind Code:
A
Abstract:
To provide composite particles that are suitably usable as an oil adsorption agent, an industrially advantageous production method of the same, and an oil adsorption agent and an oil-water separation method using the composite particles.SOLUTION: Composite particles contain a condensate of a fluoroalkyl group-containing oligomer having an alkoxysilyl group, and magnetic iron oxide particles. The particles are produced by adding alkali to a reaction raw material solution containing a fluoroalkyl group-containing oligomer having an alkoxysilyl group and magnetic iron oxide particles, and subjecting the solution to a hydrolysis reaction. There is also provided an oil adsorbent agent containing the composite particles. There are also provided an oil-water separation method that brings the oil adsorption agent into contact with a treatment liquid containing water and oil, and adsorbs oil of the treatment liquid on the oil adsorption agent.SELECTED DRAWING: Figure 1
