No, the idea is that there's 2 kinds of spells: You have the spellcasting spell-versions, and the alchemy preparation-versions. So your 'spells' are your preparation formulae, actually.
In other words, this means that a Fireball spell and a Fireball preparation are 2 different things formulae-wise.
A random rule-quote to cover my bacon:
"New spells, rituals, or alchemical preparations
can be learned by studying spell formulae or finding
some mentor (either a spirit or another Awakened
individual) to teach you."
Something NOT mentioned in the book is whether Enchanters get free preparations. I'd argue that a fair (house-)ruling would be to also give Aspected Enchanters free 'spells', which in their case means free preparation formulae.
