If a native form cation exchange resin is Na, when I recharge it can I use CaCl2 instead? Does it matter what the native form is at the beginning? Calcium form ion exchange resin is more expensive.
Can anyone enlighten me as to how to elute Pse from ion exchange resin WITHOUT having to use hydroxide , solvent and Hydrochloric acid ? I didnt pay close enough attention the first time but only evaporated . 90% yield of usable Pse..... would REALLY appreciate a reminder of proper procedure . Be safe everyone and STAY FREE....
Has anyone ever tried to extract from cactus using resin ion exchange spheres? If yes,how have u performed it?
Has anyone in this community ever tried purifying Mexican meth using Hiesenburgspecial 's ion exchange resin procedure for getting useable psuedoephedrine? Or what is the BEST way to return the shit to pre n-iso D.?
I have the following considerations and your help will be very much appreciated.
At the moment in my house I have a double array of filters in my central water supply pipes, a polypropylene filter for small particles and a Polyphosphate crystals filter for anti-scalling. So far, so good.
Currently, we have installed in our bathroom a steam generator for various breathing therapies etc. The distributor and installer of the machine we bought, installed a blue tank with softening ion-exchanhe resin prior to the steam's generator water input in order to prevent machine issues with hard water.
What I would like to know is if the polyphosphate filter is working against the water softener. Do they have the same principle of operation? Is it bad to have both of them?
Hello, can someone explain how this can happen?
I'm realizing a esterification on an organic monoterpene using an acidic ion exchange resin as a catalyst, but there's a side reaction that is hydrogenating the monoterpene. I'm using acetic anhydride for the reaction but it appears to not participate on this side reaction.
The selectivity is still good and I have a great yield, but I don't see from where this is coming
English is not my first language, so if you can't understand something please ask
Thank you
Hi all, thought this would be a good place to ask this.
I recently got a water filter jug (like brita) that is refillable. The company also sells loose refill packs, but they're very expensive and they only have two ingredients - the activated carbon, and an ion exchange resin to soften the water.
I found food-grade activated carbon, but I'm a bit stuck on the ion exchange resin. Everything is for aquariums, which I doubt is food safe, or reverse osmosis, but I'm not sure I can just put that in a filter that uses only gravity?
Any tips on what I should be looking for? I could just leave out the resin, but where I live the water is very hard so it would be a shame.
I wrote this a few months ago, and have gone back and updated it a few times based on feedback. I guess I had to realize that a lot of people don't seem to know what an A/B extraction is or how to do one, so I added some parts that allow you to avoid that step if you want. Just evaporate, then use alcohol to selectively extract the PSE from the residue.
Note that the water softener resin is NOT OPTIONAL. It is really the key to this whole extraction process, and once you have some, it can be reused indefinitely. Fortunately, it's not hard to obtain. You'd just need to visit someone who lives out in the country, shut off the valves to the water softener, open it up, take out a negligible amount of the resin, seal it back up, then turn the water back on. Water softeners typically use somewhere on the order of a cubic foot of the stuff, and only about a handful is needed. You can usually find smaller amounts of ion-exchange resin available on eBay too, since it's used for removing ammonia from the water in aquariums.
Anyway, my original writeup is here:

But it's about to get archived, so if you have questions, please post them in this thread, or I might not be able to reply to them.
The report discloses the photochemical homolytic cleavage of iodine azide after its formation accompanied with release from polymer‐bound bisazido iodate(I) anions. A series of radical reactions are reported including the 1,2‐functionlisation of alkenes and the unprecedented chemoselective oxidation of secondary alcohols in the presence of primary alcohols.

I'm seeing it beeing mentioned from time to time. It seems to be suitable for the separation of certain compounds from other compounds.
Could it hypothetically be utilized for the purification of a psilocybin / psilocin extract or alkaloid purification in general?
Is there a resin that will easily swap potassium for sodium?
I have a reaction producing the potassium salt of an organic species, and I'd like to get the sodium out instead.
Worst comes to worse I can just precipitate it as the silver salt and then react with NaCl to get the sodium, but if a nice resin exists, that would be ideal.
I've never used an ion exchange resin before, but I imagine it is simple to load the resin with sodium, rinse out the salts, and then stir up the sodium-loaded resin with the potassium salt and then filter the resin leaving me with a solution of sodium salt. Is that correct or is my assumption faulty?
For those of you familiar with ion exchange resins, need some help.
I just started familiarizing myself with these concepts for my next project at work and am having a hard time remembering the type of ions being exchanged for each resin.
From what I've read,
There are 4 types of resins (other one is just a specialty resin):
- SAC - Strong acid cation (used to exchange cations like H+)
- WAC - Weak Acid cation
- SBA - Strong Base Anion (used to exchange OH- ions)
- WBA - Weak Base Anion
I know acids are positively charged and bases are negatively charged and thats how I remember which ions are being exchanged. I'm wondering what you guys think are easy ways to remember the types of ions being exchanged for each resin and when to use a strong or weak version of each.
When shopping for replacement water filters for my Breville Barista Express, I noticed there are two types ... Charcoal (which is what I've been using), and Ion-Exchange Resin. Some sites even sell them together as a package: https://www.amazon.com/Charcoal-filters-Ion-Exchange-Replacement-Breville/dp/B01HGIPM60
Should I have a preference for one over the other? Water quality is decent in my area, and to my knowledge not particularly hard.
