Ethyl chloride and alkali carbonate reaction?


Hi guys,

I've searched but couldn't find this type of reaction anywhere. To me it looks natural that these two would automatically react like this:

2 EtCl + K2CO3 ----> Et-O-COOEt + 2 KCl

So the question is: Do they react or not? If yes, is it at an appreciable rate?

Thanks.

For starters, your reaction equation isn't balanced.

What state (solid, solution etc) do you intend your reagents to be in?

A watery solution of potassium carbonate will hydrolyse EtCl to EtOH and KCl, for instance.

I want to use potassium carbonate to sequester HCl that will be made during alkylation with EtCl in ethanol (almost anhyd.). I do not have sterically hindered bases to do the job.

Almost no one uses volatile EtCl (BP = 13 C) for alkylations. It's a fairly toxic compound.

Alkyl chlorides are the least toxic compounds of all the alkyl halides. Toxic concentration of alkyl chloride usually is unbearable because of irritation and odor.
Talking about the original post, the actuall reaction most likely will be
2 EtCl + K2CO3 -> 2 C2H4 + 2 KCl + CO2 + H2O
and it requires pretty harsh conditions (nothing will happen at room temperature).
