Web2 feb. 2024 · Ortho-, Para– and Meta– Directors. In Electrophilic Aromatic Substitution (EAS), some substituents on benzene will direct the electrophile E to the ortho– (1,2)and para– (1,4) positions. These are called, “ortho, para- directors”. Another class of substituents avoids directing the electrophile E to those positions, with the result that the meta- … WebPowerPad Deactivator. The Sensormatic PowerPad offers superior deactivation reliability at impressive throughput speeds. The PowerPad deactivates active AM EAS labels up to 17.5cm (7in) above its surface at a throughput speed of up to 200cm/sec (80in/sec) — allowing deactivation of both source-tagged and retailer-tagged merchandise.
