Synthesis Assistance THF -> GBL

Migrated topic.

StoneyBroski

I have embarked on SpiceX, still drifting through
I am working on making GBL from THF and would really appreciate some guidance from more knowledgeable members. I've done research before reaching out which I have included links to for reference.
After doing my research it looks like all I have to do is oxidize THF with an aqueous solution of sodium bromate and let it sit overnight. I am not entirely sure that's it (seems like I'm missing something.) Does anyone know more about this and have pointers you could help me out with? Would this not work and/or need to be cleaned or purified somehow?

In the laboratory, it may also be obtained via the oxidation of tetrahydrofuran (THF), for example with aqueous sodium bromate.

Reagent: NaBrO3, NaHSO3
Solvent: H2O
Time: 16.25 hours
Temperature: 20 C
Yield 68%

Hi. Please read this:

and this:

Also, please consider this:
as applying equally to chemical reactions.

Please attach a safety assessment for your intended reaction or I will be deleting this thread.

What needs to all be included for rhe saftey assessment? Im doing this myself regardless, im just trying to get help so i dont accidentally create a toxic poison and accidentally kill myself or others.
 
Hopefully you are aware that bromate is a carcinogen, and THF has a propensity to form highly explosive peroxides.

GBL can be formed much more safely by the fermentation of glutamate.

PS: the safety assessment is something that you write as much for yourself as anyone else.

ill go at it on a whim by myself and cross my fingers.

Is the above a good idea considering you said this as well?:

My concern here is safety. Perhaps PM another member who is versed in chemistry enough to help you figure out some of the steps you need in order to be as safe as possible.

One love
