Vai jūs sapratāt, ko es jums iepriekš uzrakstīju? Jūs varat mēģināt izšķīdināt šo šķīdumu ūdenī un atdalīt no PEG, izmantojot sārmainu ekstrakciju. Iegūsiet toluolu (vai citu piemērotu šķīdinātāju) ar PseidoE brīvu bāzi). Tad skābes ekstrakcija, lai atdalītu PseiudoE no Ibuprofēna.

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.

Vienkārši... Vajag. šis pavediens ir lielākais sūds visā vietnē. Tas ir pārliecinājis mani, ka
T šajā pasaulē vairs nav palicis nekāda lepnuma. Tā vietā ir stājusies "es arī" ideoloģija, kur ikviens ir upuris visam, ko vien var atrast, lai kļūtu par upuri. Šī paaudze ir slinkākā cilvēces vēsturē. Kad esi izsalcis, tu izturi bļodu un lūdz, lai tev iedod našķus.
Kad tev ir auksti, tu stiep roku un lūdz segu. Komunisms. Tāpēc tas nekad nedarbojas. Tāpēc, ka ir atņemts stimuls censties. Neatkarīgi no tā, vai jūs smagi strādājat vai vispār nestrādājat, tie, kas smagi strādā, būs spiesti atbalstīt nestrādājošos un dalīties sava darba augļos ar cilvēkiem, kuri atsakās dalīties darba slodzē.
Es tev nepavīstu @G.Patton, tu esi vienīgā strādīgā bite pin šo pavedienu un esi atbildējis droši vien uz vairāk nekā 100 jautājumiem. Uz dažiem esi atbildējis 3 vai vairāk reižu

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.
Film coating: Opadry Y-1-7000, which consists of: hypromellose (E464), titanium dioxide (E171), macrogol 400.
Zyrtec-D tablets are packed in blisters and placed in cardboard boxes. Each tablet contains 5 mg of cetirizine dihydrochloride with immediate release and 120 mg of pseudoephedrine hydrochloride with extended release.
