Separation Funnel as Addition Funnel
Short and simple question: can I use a separation funnel as an addition funnel? I have a separation funnel but need an addition funnel and cant afford
one. The reaction is open to the air (via double necked flask and is not under vacuum.

Should not be a problem. It is commonly done. The only issues are when you have a closed system and need pressure equalisation or when you need to
protect your reagents from the air.

I'd done that several times. Works nicely, as long as you don't need to work under nitrogen.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

Thanks, I dont plan on working under vacuum that often.

The major advantage of doing additions with a jointed sep funnel instead of an addition funnel is that you can keep adding stuff to the funnel while
your reaction or distillation is running. It's nice to have a pressure equalizing funnel for running reactions that require extremely dry conditions
or inert gas, and you also don't have to monitor the reaction as closely at the end of an addition with a pressure equalized funnel.
I use my non-equalized funnel more often than my equalized funnel, but they both get used a lot.

Actually the price of Chinese glass is very reasonable, shipping takes about ten days which is not instant gratification, but makes my purchases
affordable. I have both sep and addition, in 250ml size, and have MAYBE $25US in both.

I did this while waiting for real thing. It is actually amazing how much you can improvise.
