Separation logic is a spatial logic for reasoning locally about heap structures. A decidable fragment of its assertion language was presented in , based on a bounded model property. We exploit this property to give an encoding of this fragment into a first-order logic containing only the propositional connectives, quantification over the natural numbers and equality. This result is the first translation from Separation Logic into a logic which does not depend on the heap, and provides a direct decision procedure based on well-studied algorithms for first-order logic. Moreover, our translation is compositional in the structure of formulae, whilst previous results involved enumerating either heaps or formulae arising from the bounded model property.
