White-spirit
(OP)
I've a solution of White-spirit with a known concentration of mercaptans and I want to vary this concentartion by dilution; the problem is that I have not a pur White-spirit for this. I would like, so, to know if there is an other solvant with which I can dilute my solution.
thanks advanced.
thanks advanced.





RE: White-spirit
If you say white spirit you mean Ethanol right, I suppose Propan-1-ol is a better solvent than ethanol the only problem is that it is hygroscopic, so better handle carefully.
If you are not satisfied with my answer, Can you put your question in a better way giving chemical names if possible.
RE: White-spirit
You also mention mercaptans which is common in un-hydroprocessed naphtha/Kerosene.
From that I would say that any naphtha type, clean paraffin (e.g. Hexane, heptane) etc would be equally good solvent, if thats not present an unleaded gasoline could also be used.
RE: White-spirit
Depending on their use (architectural finishes, painting, etc.) mineral "spirits" are classified as: regular, odorless, high-flash, and high-solvency.
The solvent properties that interest you were not given. If you are just looking for similar boiling points, "regular" (Stoddard) solvent, and Shellsol D40 may be acceptable additions. In this sense, a "high-flash" aromatic naphtha with an IBP 154oC and a dry point of 177oC devoided of mercaptans, may be applicable. If your "spirit" follows a given specification you should look for more details than just a distillation range. Good luck.
