Abstract
The present disclosure concerns particulate matter including insoluble, non-magnetic, inorganic oxide particles, having, on each particle's surface, a plurality of, covalently grafted, ricinoleate compounds. The particulate matter is particularly suitable for odor scavenging of heterogenous materials. Further, the present disclosure provides a method of producing the particulate matter, articles of manufacture comprising the particulate matter and methods of producing the particulate matter.
Claims31
Particulate matter comprising insoluble, non-magnetic, inorganic oxide particles, having, on each particle's surface, a plurality of, ricinoleate compounds directly covalently grafted to the surface of said particles, wherein said particulate matter is characterized by at least one of:
- (a) having sizes in the nanometric and/or micrometric ranges;
- (b) having an ATR-FTIR peak indicative of said covalent graft of ricinoleate compounds onto said insoluble particle, at least at wavenumber within the range of 800 and 1100 cm−1;
- or
- (c) said insoluble particles, without said ricinoleate compounds, having a surface area of at least 50 m2/g,
- or any combination thereof.

A method of producing particulate matter, the method comprising
- i) providing a suspension comprising insoluble inorganic oxide particles and a source of ricinoleate compounds;
- ii) subjecting said suspension to at least a sonication process;
- and
- iii) optionally separating the particulate matter.
