BTW, the "Synthol" mentioned on that webpage was a synthetic kerosene
replacement that had a higher specific impulse, developed to allow the
Soyuz booster to carry more payload into orbit. It was also known as
"Sintin".
Unfortunately, when the Soviet Union collapsed the only factory that
produced it ended up in another country, and Russia no longer had access
to it.
