In the traditional sense, there is a significant difference in that purchasing merely reflects the act of acquisition, while procurement encompasses more elements of the supply chain (re logistics, transportation etc.).

1)AIMS OF effective PROCUREMENT
-cutting over input costs
- identifying world class suppliers
- maintaining of quality stardards thru quality purchase.
-ensuring continuous organisations operations thru steady supply of inputs
-buying all inputs needed in operations and productions.
-risk identification, assessment of its impact to the organistion
-disposal of under utilised resources like capital assests old equipments etc

Based on the above, the importance of differentiating between purchasing and procurement while interesting is at the end of the day an exercise in futility. Therefore you need to look beyond the scope of functional distinctions to see and understand the broader role your profession plays in the day-to-day success of your organization.
Then, and only then will you be able to make the contribution in which all purchasing/procurement professionals are capable of providing.
