Tak, trzeba to zrobić w pierwszej kolejności. Nie wiem, w czym tkwi problem. Nie mogę zgadnąć i odpowiedzieć bez szczegółowego wyjaśnienia procedury.
Ok, google: vm&p naphtha composition
następnie musisz wybrać ten sam lub podobny. Myślę, że kerozyna jest najlepsza. Czy widzisz, że wystarczy użyć google i zapytać? To naprawdę działa dobrze w przypadku prostych pytań, takich jak twoje.

Czy mogę wziąć to za lekki eter naftowy (25C do 80C)? zamiast ciężkiego.

Rgr That!
Nigdy nie znam odpowiedniego odpowiednika naphty, gdy mówi się "bez zamiennika"
naphta= eter naftowy

hey, how can I extract 40mg ephedrine HCl from 50mg tablets? the tablets also contain Gelatin
Solani amylum
Lactosum monohydricum
Talcum
Cellulosum microcristallinum (E 460)
Glycerolum 85% (E422) is it enough to dissolve the tablets in water and then filter them and evaporate the filtrate?

You can filter out some of the excipients by dissolving the ground up tablets in cold water. But not all of them.
please someone HELP MY PILLS CONTAIN THIS
Substances actives : paracétamol,Pseudoéphédrine chlorhydrate
Excipients : Amidon de blé, Amidon de pomme de terre, Lactose, Magnésium stéarate, Sodium carboxyméthylamidon

I would like to ask Barton Mbuye. According to the literal meaning of "Usage Method 2", I have now completed needle-shaped crystals like Pu Gongying seeds. Barton Mbuye, is it just a "semi-finished product extracted from pills"? Pseudoephedrine cannot be used Blue fire heating in entertainment? You still have to go through a very complicated reduction process. The sodium cyanoborohydride reductive amination process. Or the sodium borohydride reductive amination process. I am now stuck. Please also ask the great Master Barton to point out the inferior ones and break the process of reductive amination. Thank you!
Oh DEAR Alchemists.....
Please listen to my advice here :
--i played this video game on every pill formulations plattform in the universe..., so to speak...
SO THENI
please accept my gift of wisdom in this topic:
---------------------------------------------------
>>> SIMPLE to pull off... EXTRACTION INSTRUCTION <<<<
***************************************************************
[ "FOLLOW UP PRODUCT" will be of hi purity
& up to
QUANTITATIVE YIELDS ]
>> keep mechanical loss small and work with care !!!!!
====================================================
-- EXTENDED RELEASE -- type:
120 mg pseudoephedrine- HCL
5mg Cetirizine 2-HCL
|* anti allergic / decongestant |
should in my opinion always be prefered over other
remedies.
>>>> example, METHOD PROCESSING <<<<<<
~~~ 3 BOXes of 6 Tablets / 720 mg per single BOX ~~
Equipment:
- 250 ml Beaker
- Magnetic Stirrrer with heating/ stir bar
- 100 ml Syringe (with a large outlet Tip)
will be used as "charmin Filter" Column
- 250 ml Round-Bottom Flask with tiny am. of Ice Water
| used as Lid for the beaker, for nice Reflux- action |
- Evaping Dish for crystalization
Solvents / other Chemicals
25ml of dry Acetone (tech grade)
150 < 200ml of denatured Ethanol (94 - 96 % vol.)
20m ofl 2-Propanol (99%)
=================================
THE PROCEDURE !
First throw the WHOLE PILLS in to the Beaker,
add the ACETONE, this will break the Glue / Binders -
you`ll notice the Pills degrading to a gooey powder mass instantly.
swirl them a bit around in the Vessel,
now add the first dash of Ethanol (150ml) at Once.
Put the RBF with Cold Wather on top of Beaker,
heat your Plate up to 150*C , keep moderate constant stirring .
let the Pill -MASS dissolve completely / till Liquid looks like
Milk / all big chunks have become a fine powder, thats settling at Bottom.
Prepare the Big Food Syringe , to act as a Filtration Column:
1.) Use Charmin -like multi Layered Paper towel----> Seperate
one Layer off the single Sheet, now shred it in to a nice Pile
of fluffy little Tissue pieces by Hand...
pack those paper towel shreds in to the Syringe, after Pulling out its Plunger .
make a nice Filtration Layer ,
Compress it till the spaces are covered, but not to tight !
Solvate the Filtering Material with Ethanol generously....
NOW POUR THE HOT EXTRACTION Mass trough the
prepared filter syringe-column... ( let it suspend , clamped on to
lab -stand like you would do with common condenser etc.)
RINSE THE BEAKER with additional 50mls of EtOH
if filtering is complete --> ! USE THE SYRINGE PLUNGER
PUT IT BACK IN TO SYRINGE, where the " Pill -Mush "is now
on top of the charmin layer....
NOW PRESS EVERY LAST DROP OUT OF THE SYRINGE CONTENT
Pour the Milky X-tract in a large pyrex dish,
throw a stirbar in,
turn heat up to 250*C
keep a nice and steady but slow stirring,
let a portable strong handheld Fan blow Air over evaporating SURFACE
try to keep around 65*C temperature and gently boiling will quickly evape the Solvents
away!
<<<< VENTILATION OF WORKSPACE IS REQUIRED >>>>>>>>>>
lower the heat until you have a crude crystaline layer left in DISH
now flush WITH A GENEROUS AMOUNT OF DRY n COLD ACTEONE
USE SPATULA Scrape and finely divide de crystalline Mass in the Acetone, rinse it 2-3 times that way, COLLECT the Acetone Washings put em a side ( the antihistaminic is now outta the way....)
Now redissolve theCrude PSE HCL in a sufficient amount of isopropanol, until completely dissolved...
filter trough granulated active carbon / britta filter and fine filter paper..
let the PSE CRYSTALS SLOWLY FORM AT ROOM TEMP. , rinse them a final time with tiny bit of ACETONE.
YOU SHOULD NOW BE LEFT WITH ALMOST EVERY BIT OF SOURCE MATERIAL, IN A PERFECT
FORM OF MANY NEEDLE LIKE CRYSTALS 1
IF YOU FOLLOW MY iNSTRUCTION
i guarantee you A impressive result IN purity + quality
IMPORTANT ADVICE
AVOID PILLs THAT CONTAIN
> POVIDONE<
AT ALL COST
Because they require to much extra pre-treatment....
==============
__** NOTE **_____
> IBUPROPHENE <
separation> the
-" easy way"
----->
LIKE THIS:
in case you have to use ibuprofene containing pills, ground /mortar them as fine as possible,
Use Mineral Spirits/ lighter Fluid or absolute dry / chilled Acetone
completely cover the powder with liquid,
stir with mag strir,/
lett pill mass settle,
DISCARD THE SOLVENT / REPEAT STEP A SECOND TIME. IF YOU LET IT STAND ,
YOULL NOTICE A BIG & SPARKLING
IBUPROFENE CRYSTAL "MOUNTAIN" WILL APPEAR OUT OF THE LIQUID:
LET THE TREATED PILL POWDER DRY COMPLETELY BEFORE YOU FURTHER PROCESS:
SO THAT WOULD BE MY CONTRIBUTION IN THIS FIELD OF WORK,
I INVESTED TIME & LOVE TO THIS WRITEUP; HOPE some will enjoy it
cheers
