DMSO distillation at normal pressure
Is it possible to distill DMSO at normal pressure without damaging it? I have contaminated DMSO that has salt and other solid impurities in it whose
boiling points are off scale compared to DMSO so I thought I just use brute force with high power gas burner and distill it straight.
I need to recover the salts solved in DMSO too, but they are not affected until temp reaches some 700 degrees.

It depends on what it contains. DMSO slowly decomposes at its normal b.p. if it contains certain impurities. See Gaylord Chemical's TECHNICAL BULLETIN REACTION SOLVENT DIMETHYL SULFOXIDE (DMSO). Why don't you just vacuum distil it?
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)
