• The silanols on the surface of silica gel were chlorinated and a phenyl group was introduced onto the silica gel (<U>Remark: Graphics omitted.</U>) by phenylating with phenyllithium. The surface group was derived to a structure similar to Sudan I by nitration, reduction, diazotization, and coupling (with 2-naphthol). The prepared pigment showed approximately the same color as Sudan I, and had very good resistance to water.
