Latest Patents

Chugai holds a patent for a method of producing fine-disperse alkylated silica compounds. This method involves treating starting fine-disperse silica with water vapors at a temperature of 110°C to 120°C to achieve a specific degree of humidification. The humidified silica is then treated with vapors of alkylchlorosilane at temperatures ranging from 250°C to 310°C. This process allows for the control of the concentration of grafted alkyl groups in the final product, which can range from 4.7 to 8.0 micromoles per square meter of SiO₂ surface. The resultant products exhibit excellent hydrophobic properties, making them suitable as thickeners for lubrication materials.
