I have test fired motors with KNXY (xylitol-based), it makes a very nice
propellant, low casting point (92-96C according to Wikipedia).
Significantly slower burn rate which is also nice and makes for
longer-burning motors. But IIRC it takes a couple of days to cure similar
to KNSB. Biggest drawback is price of Xylitol, here it is expensive.

Sugars (or sugar alcohols) with low melting points may tend to crystallize
very poorly: I did some experiments with pure xylitol. Crystallization only
started after the addition of a seed crystal (and was slow).

Betreff [sugpro] Re: Allulose?
No, in fact, I have never heard of allulose. So...off to Wikipedia..
also known as:
D-Psicose , D-allulose
Chemical formula (C6H12O6)...which is same as dextrose.
Melting point 58 °C
Wow, that is a low melting point. Now allulose is getting more
interesting. What is the cost?

Has anyone worked with Allulose as a fuel for sugar propellant?
