Italian term or phrase:trov.%: S 19.06 per ...
Il distillato, per raffredamento, lascia separare il prodotto cercato che viene raccolto, seccato all'aria e poi purificato da etere di petrolio. Aghi leggermente gialli, p.f. 41-42°.
***trov.%: S 19.06;
per C7H4ClNS calc. : 18.91.***
I am assuming these are abbreviations for the expression of the caluclation or the formula.
My question is what does "trov.%: S" mean? and does the "per" mean "multiplied by" or "for" in this context?
