I suggest you to wash with hexane several times.

Sergei Tarasov

..... and then use vacuum drying

Sunil Kumar Rai

If you want to remove the residual kerosene from your powdered compound. Please dissolve the compound in a solvent in which compound is completely soluble. Then add an anti-solvent (like hexane or other) to get a ppt. Then filter and wash with suitable solvent. If you want to remove kerosene 100%, please go for recrystallization.

Abbas Mohammadi

You can wash it with H2SO4 several times.
