Aniline in Beaker
Recently I finished preparing a nice batch of nitrobenzene from benzene and am planning to reduce it to aniline, but ran into a problem where the only
video I've seen on the process uses a lot of equipment that I don't have like a mechanical stirrer and a three-neck RBF. I'm wondering; can this
procedure be done in a beaker with hand-stirring with a glass rod?

In theory it may be feasible to perform this reaction in a beaker with hand stirring, but ultimately the reaction yield would be poor. Without
sufficient agitation, the reaction rate is considerably slower, and complete conversion to aniline is unlikely in a reasonable amount of time. An
overhead stirrer is the best way to achieve adequate mixing.
On a side note, the reaction you plan to execute requires a steam distillation. For these distillations, a two or three-neck round bottom flask is
typically employed as the main distillation flask (steam comes in one side and the vapor mixture leaves the other). However, a single-neck flask can
also be used when coupled with a Claisen adapter. What do you plan to use as a distillation vessel?

I plan to do a steam distillation by simply adding water to the flask and mixing it thoroughly while distilling.

You will need a fairly large flask to contain the entire reaction mixture in addition to the extra water required to generate steam.

Well, my largest RBF is 500ml and my largest beaker and Erlenmeyer are 1000ml, but I can just scale everything down.

You can always position an addition funnel at the top of the still head to add more water as it is distilled away.
