The invention relates to the production of 2-octyl acrylate of high purity and in good yield, that includes the recycling of economically upgradable products, such as un-reacted reactants and catalyst. A terminal platform having a connecting terminal provides wiring for the positive-electrode side rectifying element and the negative-electrode side rectifying element. This presents a challenge as the mobile devices cannot themselves determine if the cell they are currently located in is congested. The second amplifier module includes an operational transconductance amplifier.
