# Role of NaOH in synthesis of Dithiocarbamate?

What is the role of NaOH in a given reaction. whether It act as a base to removal proton from amine or just to provide Na ion for the synthesis of sod. dithiocarbamate?

Proposed mechanism

$\ce{NaOH}$ is used as a base to remove the amine proton, which improves the nucleophilic power of the molecule. This way the addition to the double bond in $\ce{CS2}$ is favoured.
