What's the best procedure for making salicylic acid? Answered

Is it possible to make salicylic acid from aspirin using pretty common household gear?  If not, what would be the procedure for deriving it from willow? and what kind of willow to use?  Would it be more cost effective to buy crystalline salicylic acid?  Bonus Question:  What ppm would be good for using it as a facial cleanser and an anti-dandruff shampoo? or rather, what ppm would be bad? If it matters, I've done a year of chemistry and a year of organic chemistry with labs.  I sucked at the classes but rocked the labs like KISS at an assisted-living activity day.

Chemicals people would want to make?

Basically I want to know what lab chemicals you want to make, if you know how to make any useful chemicals. please post, I am not responsible for and injury's, fatality's, or "bad things" of any sort that come from this thread, all things posted here are to assumed for informational purposes only.

GID Vials, Tritium, TRASERS, Powders and Chemicals GLOW IN THE DARK!

TRITIUM! So I get a lot of questions from my post and instructables. Tritium Vials are Radioactive Hydrogen H3, also known as hydrogen-3 is a radioactive isotope of hydrogen. It is contained in small glass vials coated in colored phosphor then encased in glass or sealed plastics. These are commonly seen in Gun Sights, Watches (TRASERS) and some Emergency Exit Signs. http://en.wikipedia.org/wiki/Tritium_illumination Small amounts are legal and for approved uses. Read the NRC guides Typically the Trit vials are small, expensive and dim. The latest GID (Glow in the Dark) Chemsticks, LED's and GID Powders or paints seems much more effective and usable. * Cyalume, as used in a lightsticks, emits light by chemiluminescence of a fluorescent dye (also called fluorescor) activated by cyalume reacting with hydrogen peroxide in the presence of a catalyst, such as sodium salicylate. It is the most efficient chemiluminescent reaction known. up to 15% quantum efficiency. http://en.wikipedia.org/wiki/Chemiluminescence New LED low power requirements and high Lumen or light output have provided many solutions that are low cost, high power and longer lasting. GID Paint or Powders are "charged" with light or daylight sources as with your traditional kids toys or stickers. New products are brighter, glow longer and are now waterproof, have many colors and applications. http://www.4physics.com/catalog/GIDinfo.php Also this is occasionally confused with the chemical illumination. However these paints powders and materials use common phosphorescent materials include zinc sulfide and strontium aluminate. Use of zinc sulfide for safety related products dates back to the 1930s. However, the development of strontium oxide aluminate, with a luminance approximately 10 times greater than zinc sulfide, has relegated most zinc sulfide based products to the novelty category. Strontium oxide aluminate based pigments are now used in exit signs, pathway marking, and other safety related signage. http://en.wikipedia.org/wiki/Phosphorescence Hope this helps! 01/2011 - Update Source for Materials http://www.darkniteglow.com/glow-shop/ ERCK www.Candlepowerforums.com Additional Tritium Resources * U.S. NRC: http://www.nrc.gov/reactors/operating/ops-experience/grndwtr-contam-tritium.html * U.S. EPA: http://www.epa.gov/radiation/radionuclides/tritium.htm * U.S. DOE (Argonne National Lab): http://www.ead.anl.gov/pub/doc/tritium.pdf * California EPA: http://www.oehha.ca.gov/water/phg/allphgs.html * University of Idaho: http://www.physics.isu.edu/radinf/tritium.htm
