How is naphthalene-1-sulfonic acid prepared?

According to the "Tiangong Kaiwu", the method of preparing Arsenic-1-Realgar is as follows:
Where the Arsenic is burned, the earth kiln is lowered, the stone is placed on it, and the curvature is built on it, and the top is hung upside down with an iron kettle. The charcoal is burned under it to raise the fire. The smoke from the curvature is fumigated on the kettle. It has been pasted on a layer, and the thick knot is inch, and the fire is resumed. When the smoke in front is cold, the fire is held again, and the fumigation is pasted as before. Several layers in a kettle are full, and then it is lifted, and the kettle is destroyed and the Arsenic is taken. Therefore, there is iron
To make Arsenic-1-Realgar by this method, first place the raw ore at the bottom of the earth kiln, build a curved flue above, and cover the iron kettle upside down at the flue outlet. A charcoal fire is ignited below to heat the ore to produce smoke, which is fumigated along the curved flue and attached to the upside-down iron kettle. After the smoke fumigates on the iron kettle to form a layer of material about one inch thick, stop heating. Wait for the smoke to cool, ignite the fumigation paste again, and repeat until the iron kettle is covered with several layers. Finally, remove the iron kettle and break the iron kettle to obtain Arsenic-1-Realgar. Due to this preparation method, there is often iron sand at the bottom of Pi-1-Realgar, that is, the residue of damaged iron kettle.
