Can spandex be dissolved? Yes it can. N-Methyl-2-pyrrolidone (NMP) is one chemical that will dissolve spandex (am looking for others).Keep in mind that its incredibly rare to have a piece of fabric comprised of 100% spandex. Generally polyester is blended with spandex in 85:15 or 90:10 ratios to give a material stretchiness. But NMP will dissolve spandex fibers from a spandex spool, but will not touch the polyester fibers.
How to calculate lambda max for Dienes and trienes (etc) in the ring system .Woodward and Fieser's rules for estimating the position of the maximum absorbance wavelength in ultraviolet spectroscopy:1. If the parent is heteroannular diene(which is decided by checking the presence of atlist two conjugated double bond in the ring), start with 214. For homoannular is the system containing twoconjugated double bond in six member ring, begin with 253.2. Add 30 for each double bond which extends the conjugation and check its potion with the double bond of system if it in cis position then add 39 nm,for trans addition is nil3. Add 5 for each carbon substituent on the double bonds4. Add 5 for exocyclic double bonds.5. The numbe you ow have is the calulated maximum absorbance wavelength (lambda max) in nanometers (nm)NOTE: The terms here are not quite as self explanatory as you might think, and change where carbonyl conjugaion etc come into it (parent conjugated carbonyl system: Start with 215, alpha organic substituent: add 10, beta: add 12, gamma/delta: add 18, exocyclic DB: add 5, presence of a homodiene system: add 39, C1 substituent does not seem to add anything) etc. So look them up; or better yet, find a textbook. To test yourself take a look at cholesta-2,4,6-triene; you should get 303nm (the 4-5 DB is exocyclic)

N-Methylpyrrolidone (NMP) is considered as SVHC (Substance of Very High Concern) by EU authorities (ECHA) and on the candidate list since Feb. 2011. This process is ongoing until begin of April 2011. NMP may damage the unborn child (teratogenic).
If you have a vanity table dated April 18, 1923 made by NMP CO and are trying to find value and have picture, you should first look on antique auction sites. You may be able to find the antique vintage table on some auction websites and compare the tables with yours.

Yes he did it was the one where two kids (Cameron was the boy) he guest starred
1-methyl-2-pyrrolidone (NMP), is the most commonly used, but DMF, m-cresol, HFIP and some others will also work.
