Pochopili ste, čo som vám napísal vyššie? Môžete skúsiť tento roztok rozpustiť vo vode a oddeliť od PEG alkalickou extrakciou. Získate toluén (alebo iné vhodné rozpúšťadlo) s voľnou bázou PseudoE). Potom sa kyslou extrakciou oddelí PseudoE od Ibuprofénu.

He will get a massive emulsion because that peg is loading in their with a non ionic surfactant meant to encased anything in there as soon as the pH is raised...

Are these methods still good or have things changed. The problem inactives that is see in my pill in trying to extract is polyethylene glycol....polysorbate 80...and hypromellous... the rest of the stuff can be dealt with... there some wax also. Ill send a picture of the inactive ingredients. The pills are red 30mg film covered and it seems they dont have providone in them. The surfactant in there makes an absolute mess if you add base which I tried first the old normal way just to see what happens. I haven't tried doing this in awhile and the pills have definitely changed. Thanks if you can help.

Len... Wow. toto vlákno je najväčšia sračka na celej stránke. Presvedčilo ma, že
T na tomto svete už nie je žiadna hrdosť. Nahradila ju ideológia "ja tiež", kde je každý obeťou všetkého, čo si nájde, aby sa stal obeťou. Táto generácia je najlenivejšia v dejinách ľudstva. Keď ste hladní, , vystrčíte misku a prosíte o jedlo.
Keď ti je zima, natiahneš ruku a prosíš o deku. Komunizmus. Preto nikdy nefunguje. Pretože motivácia snažiť sa bola odobratá. Bez ohľadu na to, či pracujete tvrdo, alebo vôbec, tí, ktorí tvrdo pracujú, budú nútení podporovať nepracujúcich a deliť sa o plody svojej práce s ľuďmi, ktorí sa odmietajú podeliť o pracovnú záťaž
Nezávidím ti @G.Patton, ty si jediná pracujúca včela, ktorá pripína toto vlákno a odpovedala si pravdepodobne na viac ako 100 otázok. Na niektoré ste odpovedali trikrát alebo viackrát

Can someone help with this type of pill. Since I know it can't be dissolved in water. They told me to dissolve it in alcohol and then I'm not sure. Is it toluene or what?
zyrtec-d The active substances are: cetirizine dihydrochloride and pseudoephedrine hydrochloride.

The other ingredients are:

Tablet core: hypromellose, microcrystalline cellulose, silicon dioxide, colloidal anhydrous, magnesium stearate, lactose monohydrate, croscarmellose sodium.
