Oh yeah, thank you Jim and Hans, I forgot that \frac is only in math-mode possible.

But if I want to use \chemical{Na + H_2O → NaOH + \frac{1}{2} H_2} %\frac or variants of it it doesn't work. \chemical{Na + H_2O → NaOh +}\frac{1}{2}\chemical{H_2} doesn't work too. \startformula \chemical{Na + H_2O → NaOH +}\xxfrac{1}{2}\chemical{H_2} % and some other variants of \frac \stopformula does work, but the distance between + and the \frac-expression is to large. Any hints?At the risk of using the frowned-upon $ syntax, have you tried \chemical{Na + H_2O → NaOH + $\frac{1}{2}$ H_2} This works for me, without the extra space of your last try.
